Basswood body on guitar , sucks?

First of all,the type of wood affects the tone of a guitar or bass,along with many other factors,like bridge,pickups,amp etc.Scotty Groove may say it doesn't,but ask any professional luthier and he/she will tell you otherwise.If the material wouldn't affect the tone,they could just slap some pickups on a plastic board and make a guitar/bass out of it and trust me,it's not that they didn't tried it over the last decades.The only company I know, that makes good sounding guitars,with a synthetic material is Aristides guitars,from The Netherlands.They use a material called ''Arium'' which is a super expensive mix of carbon,glas-fibres and other stuff.I've tried out one of their 6,000 euros superstrats and it sounded like my modded with S.Duncans,old Yamaha Pacifica,that I got for 200 Euros.That's why the big manufacturers stick with wood,maybe in the future,somebody will invent a cheap,good sounding,synthetic material that can replace tonewood.
Second,saying that basswood ''sucks'' it's like saying alder,mahagony,ash,koa or any other tonewood ''sucks''.Some musicians prefer it,like the ones I mentioned,some others don't.Like I said,I like mahagony more,put that's just personal preference.I hardly doubt,on the other hand, that guys like Satriani,EVH or even Guthrie Govan(his new Charvel sign. model has a basswood body) are ''tonedeaf''.Also John Suhr,likes basswood and makes some super expensive boutique guitars out of it,but hey what the hell does he know,right?It's more cheap then other tonewoods,because the damn tree,grows everywhere unlike mahagony,swamp ash or koa,who are tropical trees.There are also different quality grades of basswood,just like with the other woods.I highly doubt though that this one here is made out of the low grade quality basswood,they use on the cheapo chinese guitars.

Eddie used basswood for as he puts it for "tone with a maple cap to give it bite " This configuration was used with Peavey "
Joe Satriani is using guitars with basswood bodies for nearly 30 years,John Petrucci's MusicMan JP & Majesty models are also made of basswood,because it's extremely light weight and has a ''neutral'' tone in between mahagony & alder..

 I remember an interview with Angel Vivaldi,he also uses basswood guitars,where he explainend why he likes that particular tonewood.He said,it has a ''neutral'' tone,unlike the ''bright'' tone of Alder, which is great when you play with lots of gain & various effects.Personally,I prefer mahagony guitars,because I like their ''chunky'' tone but if even somebody like Petrucci has basswood in his super high-tech MusicMan guitars,it can't be that bad.

Confessions Of A Shredder: Music, a Career Choice, by Chris Gordon

Many of my students have asked my advice about becoming a full time musician and my answer is usually don't do it!Stay in school,get your degree and a consistent well paying job that will offer you decent security for you and your family. Once that is in place pursue music with no worries or headaches. If, however you feel in your heart that pursuing music full time is your calling then put your seat belt on, open your mind, increase your tolerance for bullshit, and be ready for anything!

I feel incredibly lucky to do what I do. Music has been a full time gig for me since I was a teenager and I truly love what I do. That's not to say that it's easy and every day is a walk in the park. I am constantly having to stay on top of my playing, teaching, and scheduling not to mention juggling multiple projects and maintaining my income and expenses on a daily basis.

This is not a regular job, there is no 401K (the closest thing I get to anything with a K in it is my 500K potentiometer on my guitar), no Health Care to speak of (well OK, there is beer), No vacation (unless you have some decent downtime while on tour and can go sightseeing or even hang out at a local bar), no sick days ( I have performed while burning up with a 103 temp and hallucinating!), no personal days (I have a personal hour at the bar before the show). If you are going to have any of those perks you will have to be pulling in some serious cash flow from your gigs. this most difficult thing about being a full time play is when your not working there is NO money coming in! It is also important to know that it does not pay all that well, so remember you had better love what you do because financially it is not that rewarding!  However that does not mean that it's a glorified hobby, though it is often perceived as such by the general public. The truth is that being a full time musician can be a 12 to 14 hour day that includes a multitude of tasks that include emailing, phone calls, confirmations, gig itineraries, contract faxing, show promotion, gear repair, gig research, gig bookings, financials, paying band-mates, hiring and firing band-mates, auditioning, dealing with club owners/managers, quarterly taxes, car maintenance, and if you are teaching then you must contend with student scheduling, billing, having your materials together, and of course getting paid in a timely and consistent manner. Somewhere in all of this the hope is to get a bit of time on your instrument!

Once you are full time, unless you have a personal manager, which is a big expense, you will be doing this all yourself. To get things started, it's probably a good idea to know what you will and won't do as a full time musician. Some musicians won't do weddings, pit orchestra's, or lounge gigs. I can understand this because the dress code sucks! I avoided these gigs myself for a long time unless I was performing at a friend's or student's wedding. However these gigs are a great source of income and keep the old electric twanger in your hands so it doesn't hurt to put a few of these under your belt.I recently did a Pit Orchestra gig and it was really fun! I had to brush up on my sight-reading chops and that is always a good thing. Plus I met some great musicians that I was able to network with and procure a few extra gigs!  Keep in mind that gigs like this will cost some upfront money such as a Tux, or a decent suit. Remember to write it off when you do your taxes, so keep all of your receipts! Speaking of that, once you are out there and making the money you will now be able to write almost everything you do. Guitar strings, Picks, Cables, Amps, Guitars, Guitar Straps, Clothing, Gas Mileage, Car Maintenance, etc, so keep every receipt and shop around for a good accountant that you can deal with, he or she will be an important player in your career!

Ok, so let's have a look at some avenues for income as a musician. I am going to draw from my personal experiences here so I may overlook a couple of avenues, however I would rather speak on what I know. My personal list is as follows:

1 .Performance -This includes any live performance show in any capacity: Club dates, Theater shows, Weddings, Casinos, Cooperate Events, Private Parties, Bars, Coffee Shops, Cafe's, Restaurants, Carnivals, Arenas, etc etc.

2. Instruction- Any kind of teaching of music including teaching privately, for a retail guitar outlet, at a school, or even on video,etc.

3. Session Work-Any kind of recording medium in witch you are paid for your performance on the recording. This can include performing on other artists' albums, recording and distributing your own music, commercial jingles, music production, audio engineering, audio mixing, etc.

Ultimatley, you may doing all three of these avenues to keep a steady flow coming onto your bank account. It's no secret that the industry is always in a state of flux, often changing on a daily basis so be creative, stay hungry and keep pushing the envelope. This business can be feast or famine so be prepared for both, stay humble but confident, mind open and aware, continuie to study and perfect your craft, and above all be a reliable member of the team. I have made the most advances by being a decent person and making friends so stay genuine!

Another thing, and this has been a hot topic on the web as of late, you are always responsible for your succsess, not the club owners. They have a business to run and loads to worry about, your job is you and your vision so take care of your store and promote accordingly. The bottom line with that whole isssue is that if you are good and are effecting listeners and stay consistent you will build an audience and a following. This is a business, treat it like another serious business that depends on success to thrive and stay alive. Market, brand, and aof course deliver every single night!

All the best!
Cheers!
Chris

Cubase - como apagar fragmentos audio inuteis

Outra coisa, uma "dica": faz sempre uma pasta nova para cada música que gravares.
Assim, todos os ficheiros de audio de cada música ficam guardados na sua pasta exclusiva.
Depois, quando tiveres um trabalho a avançar e já com várias pistas gravadas, vais a > Project > Pool e abres as pastas que lá estão dentro. Geralmente é uma "Audio", uma "Video" e uma "Trash".
Na janela Audio podes ver todos os fragmentos de Audio que gravaste e sob re essa zona clicas com o botão direito do rato (em PC é o botão direito) e escolhes a opção "Remove Unused Media". Seleccionas a opção de enviar para "Trash".
Depois, quando tiveres um projecto finalizado podes seleccionar, também com o botão do lado direito, a opção "Empty Trash".

Isto porque os projectos que me enviaste passaram a ocupar menos de metade do espaço de disco duro depois de ter despejado todo o "lixo" que lá estava, de ficheiros gravados e não usados.
É uma maneira de poupar espaço de disco e manter os projectos organizados.

Limpeza/manutenção da Guitarra

De tempos a tempos preciso de fazer manutenção das minhas guitarras, e como muitos sabem, as cordas custam dinheiro... ter muitas guitarras implica um investimento jeitoso de stock de cordas!!! Stock que é necessário quando se está activo profissionalmente. Conheço muitos guitarristas que deixam as cordas na guitarra para além da morte anunciada das mesmas. Isto serve para vocês também
Para estender a vida útil das cordas, convém fazer alguma manutenção das mesmas e é possível mantê-las praticamente como novas ao toque até perderem eventualmente as suas características e afinação. Comprem uma folha de lixa da mais fina que existe, pode ser uma 1000 que serve para polir metais e acabamentos de madeira. Cortem um pequeno pedaço para manusear facilmente e enrolem por baixo da corda. Vão polindo a corda suavemente ao longo da mesma até ficar livre dos detritos e de qualquer resistência que possam sentir de ferrugem. Repitam nas cordas lisas. Nas cordas enroladas, basta passar uma ou 2 vezes para limpar apenas, visto que não convém desgastar o enrolamento. Vão notar de imediato que a corda ganha o seu brilho e estalo no fretboard novamente.
Para manutenção do fretboard, usem um bom óleo de cedro e uma trincha pequena para chegarem bem a todas as zonas de braço, mesmo com as cordas postas. Deixem a madeira absorver o óleo e depois passem um pano (de micro fibras por ex.) para absorver o excesso. Podem até untar a guitarra toda com óleo, pickups, partes do hardware, parafusos, etc...A guitarra vai agradecer o óleo de cedro e não faz mal nenhum  Limpem o excesso, eventualmente vai secar e podem puxar o brilho novamente.
Daqui a uns tempos explico o que faço cada vez que meto cordas novas e quero limpar os trastes até ficarem brilhantes e sem atrito, removendo a oxidação que vai aparecendo nas zonas do braço onde menos tocamos, tipo a partir do traste XX na zona das cordas mais grossas. Garanto que o instrumento fica em perfeitas condições.

25 Things Every Guitarist Should Know...

01. Nobody likes an a-hole ...Reality check:
Most musicians don't give a damn whether you're the second coming of Jimi, Eddie or Buck Dharma. They just want someone with a good attitude who will play the parts correctly. And since most of your time is spent offstage, relating with the other musicians on a personal level becomes as important as relating to them musically. Remember-no one is indispensable. Just ask David Lee Roth.

02. Having a great feel is your most important musical asset.
 No one will want to play with you if you have bad time. You must have a great feel-it's that simple. By "great feel" I mean the ability to lock in with the rhythm section and produce a track that grooves. If there's one thing I would recommend you to constantly work on, it's developing your groove. Listen to the greats to learn how grooves should be played: from rock (Led Zeppelin's "Whole Lotta Love" to 16th-note funk (James Brown's "Sex Machine") to blues shuffle ("Pride and Joy" by Stevie Ray Vaughan). Tape yourself (with a metronome) playing them-you'll be able to isolate and work on your problem areas. Or pick up the excellent JamTrax series (Music Sales), a series of play-along tapes covering everything from blues to alternative to metal, to stay in shape. This is the one area where you should be most brutal in your self-assessment. You'll be a much better player for it.

03. Develop your own sound
There's no better way to learn how to play than to cop licks from your favorite guitarists. The problem to watch out for is when you start sounding too much like your favorite player. Remember, rules, especially musical rules, are made to be broken.

04. Be on time
You wouldn't believe how many musicians don't believe that punctuality is important. It is crucial.

05. Listen, listen, listen!
When you're on stage or in the studio, don't be in your own world-listen and interact with the other musicians you're working with. React to what they're playing. Don't play too loud or get in the way when someone else is soloing. Put their egos ahead of yours-your number will always be called if the other musicians feel that you made them sound better.

06. Know what you want to be
 The most successful people in the music business are totally focused-they have specific goals in mind and do whatever is necessary to achieve them. The simple realization that you don't have to be a musician to be a rock star and don't have to be a rock star to be a musician can spare you years of cynicism and bitterness.

 07. Play for the song, not for yourself
It's imperative to play what's idiomatically correct. For example, don't play Yngwie licks on Bush's "Glycerine" or a noodly jazz solo on Soundgarden's "Outshined," no matter how much it impresses you. I learned this the hard way while auditioning for a punk singer. I thought I'd show her what a good, well-rounded musician I was and ended a thrash song in A with an Am(add9) chord, instead of a more appropriate A5. I was promptly shown the door.

08. Play with musicians who are better (and better known) than you
There's no faster way to improve and jump up to the next level than to play with great musicians. You'll learn the tricks of the trade, and pick up on their years of experience in the trenches, as well. But if you want to be a star, there's no better way to kick-start your career than by ingratiating yourself with someone famous and be seen sycophantically swilling drinks with him or her at the coolest bar in town.

09. Less is more
Most players you hear or read about pay lip service to what has become the guitardom's ultimate cliché. The fact is, though, what's glibly easy to say is not necessarily easy to do. I learned this on a gig backing up a singer on a cruise ship (It was the actual "Love Boat!"). Back then, I couldn't read music or play over changes very well, so during the first show, in abject fear, I played very sparsely-only what I was sure would work. After the show, the singer told me she had never worked with so sensitive an accompanist.


10. Image does matter This is one of the sad truths about the music business. The good news, however, is that not every musical situation calls for the same image. So use some common sense-if you're going to be auditioning for a wimpy jangle band, don't come dressed like a Marilyn Manson cast-off.

11. It's essential to have a great touch, or vibrato
There are players who say it took them 10-15 years to develop a great vibrato. They're the lucky ones-most never find it. Your touch is like your fingerprints-it's what distinguishes your blues playing, for instance, from that of countless other guitarists. Think of B.B. King or Jimi Hendrix-they are instantly recognizable. There are two main types of vibrato: one generated by the wrist (a la Hendrix and B.B. King) and the other from the fingers (favored more by classical guitarists). To determine which type works for you, check out your favorite guitarists' vibratos and try to imitate them. You can also pick up B.B. King's video Bluesmaster (Volume 1) to see his unique "bee-sting" vibrato demonstrated in-depth.

12. Get your sound/tone together
I can't emphasize enough how important this is. Know your gear well enough so that it works for you, not against you. For example, if you're looking for a Stevie Ray tone, you won't get it with a Les Paul going through a Marshall. You'll need a Strat running through a Fender Bassman (with an Ibanez Tube Screamer for extra punch). Unless you're a studio tech-head, a great guitar and amp (with an overdrive or chorus pedal) will probably sound 10 times better than a refrigerator full of rack-mounted shit (believe me, I've been there).

13. Practice what you don't know, not what you do know
In order to improve, you must practice. That sounds frightening, but let me reassure you that good practicing doesn't necessarily entail sitting grimly in a basement (while the other kids are outside playing), mindlessly running scales and arpeggios-you can get all the technique you need by learning licks from your favorite guitarists. For example, Eric Johnson's intro to "Cliffs of Dover" is a veritable lexicon of minor-pentatonic ideas. Here are the three axioms of good practicing:
A. Master small bits of music first (no more than four to eight notes at a time), then connect them to form longer passages.
B. Start out playing new ideas at a slow tempo (this builds muscle memory), then gradually work up to speed. It's much better to play slow and clean than fast and sloppy.
C. Always practice with a metronome

14. Get your business chops together
Business chops are just as important as musical ones, if not more so. If you want to make money as a musician, you have to start seeing yourself as a business and your music as a product. Acting against the stereotype of a musician (you know — stupid, drunk and gullible), as hard as that may be, will show club owners and record execs that you're not a pushover.

15. Be fluent with both major and minor pentatonic scales
In rock, pop, blues or country situations, knowing these scales will enable you to get by 80 percent of the time. I heartily recommend my book Practical Pentatonics (Music Sales)-a nifty little volume that covers just about all you need to know to be comfortable using the pentatonic scale in real-life gigging situations.

16. As soon as you learn something cool, apply it immediately to a real-life musical situation
Many guitarists learn tons of licks that sound great when played in the practice room. But the minute they get on stage, they have a hard time integrating this new material into their playing. Before you learn something new, you should have an idea where you could fit it in.

17. Learn as many melodies as you can
Not only does learning melodies to tunes (any tunes) increase your repertoire, it also (subconsciously) gives you an incredibly distinct edge in developing your phrasing. Ideally, you should be able to duplicate any melody you hear.
A. Listen to how singers interpret melodies and try to mimic their phrasing on the guitar.
B. Try to play back any, and I mean any, melody you hear-be it a TV commercial, nursery rhyme or the Mister Softee ice cream truck theme.
C. Always learn a melody on more than one place on the guitar neck. You want to play the melody, not have the melody play you.

18. Know your place
When a bandleader asks you to play something a certain way, smile and do it! Don't argue. Don't pout. Don't think you know better. Don't be an asshole. You'll have plenty of time to be in charge when your three-disk epic rock opera adaptation of The Jeffersons gets picked up.

19. Contrary to popular belief, taking lessons and listening to other styles of music doesn't hurt
It never hurts to broaden your scope, no matter how great a player you already are or how much you think you've already learned all there is to know. Opening your mind to other styles and techniques makes you a better, more well-rounded musician. Period. A great teacher can inspire and enable you to develop as a creative, exciting player.

20. Learn as many tunes as possible, from start to finish
It doesn't matter what style you like to play in, the more tunes you know, the easier it is to get a gig or kick ass on a jam session. And there's no excuse for not doing it-even if you're not at the point where you can learn tunes off the recording, you can avail yourself of the hundreds of transcription books out there. Heck, you can learn five new tunes a month just by reading Guitar World!

21. Develop authority as a player
You have to get to the point where you feel as creatively comfortable in front of hundreds of people as you do in front of your sister and the dog. And the only way you can attain that authority is by putting in the time. Playing at home only gets you so far-it's imperative that you play out as soon as you can. Attend jam sessions. Take less-than-ideal gigs, just for the experience. Take any gigs, for that matter-it's the experience that counts!

22. Hang out with other musicians
The best way to get contacts and gigs is to be seen and heard. How can anyone recommend you if they don't know who you are? As unpleasant and greasy as this may sound, do your best to befriend other guitarists. Though there's intense competition amongst players, most of your work will come as a result of recommendations made by other guitarists.

23. Know the fundamentals
Being able to hear common chord changes will help you learn tunes off the radio faster. Knowing a little basic theory will help you with your songwriting and your ability to intuitively come up with rhythm parts. For example, knowing that the harmonic structure of most blues tunes is I-IV-V (C-F-G) and that early rock ballads were usually built on I-vi-IV-V progressions (C-Am-F-G) will help you to play just about any tune in those genres or compose one of your own. One more plug: you also might want to check out my book The Advanced Guitar Case Chord Book (Music Sales) to get an idea of how to apply cool chord voicings to common progressions in all types of music.

24. Be careful out there
As soon as you or your band become somewhat popular, all sorts of characters are going to start crawling out of the gutter with designs on you. Have fun, but don't go overboard. And always keep an eye on your equipment-it's your life's blood. And try to save some cash.

25. Don't s#!t where you eat
Don't f*** the singer. Don't fuck the drummer's girlfriend. Don't f*** the drummer's dog. Don't f*** the drummer. Don't backstab your bandmates. Don't pocket tips. Don't be an a-hole!

17 Ways to Kill a Music Career...

(1) Having a shitty, entitled attitude.
If you’re showing up late for gigs, not rehearsing, not supporting your scene, being a dick to your band-mates, and not working slavishly to cultivate your audience online and off, you’re doing a great job of killing your potential career. Now more than ever, the future doesn’t belong to bands that have crappy work ethics.

(2) Being addicted to any substance.
Everyone makes their own choices about drugs, including alcohol. But when those choices downwardly spiral into full-blown addiction, it can quickly threaten the survival of a band. Irritability, missed appointments, detachment, and unexplained absences are the better outcomes; problems with the law, missed shows, stealing from bandmates, violence and death are where things inevitably end if left unchecked.

(3) Relying on a label, manager or anyone besides yourself to build your career.
Even with a label deal, bands can find themselves de-prioritized, or flat-out ignored. But these days labels rarely sign bands that aren’t successfully working and developing their audiences to begin with. Which means that DIY isn’t some alternative approach, it’s essential for the survival, breakthrough, and growth of any artist.

(4) Choosing a name that another band is using.
The costs of picking a name that is already being used include fan confusion, extreme difficulty growing your brand, and lawsuits. So before you pick a name, Google it, check ReverbNation, even check on MySpace. After that, do a trademark search.

(5) Not having a serious web presence.
It’s impossible to be everywhere, but you need to try. That not only means hitting all the usual (and massive) suspects like Facebook, Twitter, and YouTube, but infiltrating sites that attract your target demographic. It also means interacting with the non-stop flow of fans, as much as you possibly can.

Because if you’re not there, eventually they won’t be, either.



(6) Not selling merchandise.
If you’re not setting up a stand at all shows possible with a full range of merchandise, you’re missing out on income that could fill your gas tank and pay for meals (i.e., stuff you need to survive). And if you’re not working the crowd (on-stage and off) and putting the stand in a prominent, well-lit place with credit card processing capabilities, you’re missing out on even more money.

(7) Not touring.
Some artists, like Zoe Keating, make a bulk of their earnings from recordings. But that is getting harder and harder to do, especially as the recording continues to devaluate. Which means if you can’t tour, you’re probably cutting off a huge revenue source.

(8) Making music that sucks.
Forget about sucking: if your music isn’t outrageously great in the eyes of a significant fan base, major changes need to be made. That includes scrapping the band and starting another one.

(9) Choosing band-mates that don’t share your work ethic, goals, or long-term vision.
A band is like a family, except that you can choose the members. If your bandmates aren’t working as hard as you are, aren’t as dedicated or simply aren’t team players, they will distract and drag down your chances of success in an extremely demanding and competitive environment.

(10) Not being completely available.
A good manager will feed you opportunities, online and off, because that’s what you paid him to do. You need to show up to them, and feed the momentum.

The era of the distanced, untouchable rock star has ended.

(11) Being in it ONLY for the money.
You’re delusional and will probably make more money working at McDonald’s. The reality of this business is that an extremely large percentage of artists are poor, and most of the successful ones were poor at one time. Which means if you’re not motivated by the the music, the passion to create and play, and the cameraderie of it all, you should honestly be doing something else.

(12) Paying to inflate; Twitter followers, Facebook likes, and YouTube views.
Labels, venues, and potential managers are all-too-familiar with these scams. But more importantly, paying for fake followers distracts precious resources away from developing organic fans, the lifeblood of any successful artist.

Without real fans, you don’t have a real band, period.



(13) Insisting on recording drunk or seriously high.
It takes twice as long and twice as much to record that way, and the results are half as good. Remember: a recording (whether a single, EP, album, or video) is a permanent record of your artistic accomplishment that can convert millions of fans for decades to come. A crappy recording rarely has the same power. Don't get stoned or drunk to record, ever!

(14) Giving away way too much free music.
This is an error that rappers frequently make, especially when it comes to mixtapes. Because not all of your music has to be free, at least the part that you control. Ultimately, rappers that fail the strategically use mixtapes to promote paid, more structured releases fail to;

(a) generate any meaningful income from their recordings;

(b) encourage their fan bases to pay (or at least give them the opportunity to pay); and

(c) create any meaningful sales record for prospective investors (like labels).

(15) Delivering crappy press-kits.
Venues and festivals typically have tens of thousands of applicants to sift through, and just a few slots to award. A powerful, well-crafted press kit dramatically increases the chances of getting the gig and catapulting a career; a mediocre kit almost guarantees a quick delete.

(16a) Paying to play shows.
This seems to be mostly happening in hip-hop, where shady promoters actually charge a rapper to open for a larger act or participate in a showcase. But this is absolutely the wrong direction to go, especially since it sacrifices real revenue for ‘exposure’ that they typically can’t afford, while the promoter reaps all the upside.

Avoid these deals at all cost, whatever that cost may be.

(16b) Paying to be mentioned on a show flyer.
Why would you do that? Stop the madness. Right now.

(17) Having a violent audience.
It’s hard enough to attract dedicated fans; it’s almost impossible to choose the fans you have. But fans that routinely start fights, incite violence, or bring weapons to shows can seriously threaten the survival of an artist, simply because venue owners and promoters will avoid this artist at all costs. Which means, effectively, you can’t show up for work.

You must develop a strategy to deal with this problem, or risk choking off a critical revenue source.

Inversão de fase na gravação

A inversão de fase significa que (no caso das guitarras desta produção) a soma do som do canal esquerdo ao som do canal direito, resulta em silêncio.
Isso acontece porque enquanto de um lado sucede uma onda positiva, o mesmo som no lado oposto, apresenta uma onda negativa.
Quando se somam, cancelam-se.
Pode suceder por vários motivos:
. Os cabos de sinal (de efeitos das guitarras ou de microfones) à esquerda e à direita estão com ligações invertidas.
. Os microfones usados na gravação das guitarras foram colocados numa posição tal que o sinal que chegava a um se apresentava na fase oposta da onda que se apresentava no outro microfone.
