Q.
A. You *can* hear destructive interference, if you play a minor 2nd, (for example A and A-flat.) You may also be able to hear faint beats in a major third (C, E)
Most common intervals and chords you will hear played on a piano are "consonant," meaning the frequencies tend to "line up" and not strongly interfere with each other. Two pitches are "consonant" if their frequencies form an exact ratio of whole numbers. For example, in an octave, the simplest interval, the ratio of the frequencies is 2:1
Modern pianos are tuned using "twelve tone even temperament", or "12-TET." Specifically, the ratio between the frequencies of any two keys on the piano is
f2 / f1 = 2^(n /12)
where n is how far apart the two keys are(considering both black and white keys.)
For a major third to be *exactly* consonant, it needs to have a frequency ratio of exactly 5/4 = 1.25. But using even temperament, the ratio between the notes C and E (for example) is 2^(4/12) = 1.2599, so on a piano, major thirds tend to be slightly sharp. If you listen carefully, you can hear the dissonance in thirds, even on a well tuned piano. The interference in minor seconds is simply because the notes are so close together.
Even temperament gives relatively good consonance for seconds, fourths, fifths, and sevenths, but causes thirds and sixths to be slightly out-of-tune.......a bit of a musical compromise. However, most piano music has a relatively large number of notes played at the same time, and is played quickly enough, that any dissonance is hard to distinguish from background noise. In practice, even temperament tends to sound more "harmonious" than other systems where the intervals would be exact.
Hope that's not too confusing,

Could anyone coach me through singing?
Q. Please I need someone with experience to coach me through singing. I can't afford to pay for a coach. Another thing is to me my voice does not sound good at all. Email me if you want to help. Shizu50@yahoo.com
A. I can't take the time to actually give lessons, but I can give some advice that helped me achieve a near 4 octave vocal range.
Some things are obvious..
1.Always stay well hydrated when practicing your singing.. Otherwise, you may damage your chords.
2.Don't push yourself to hard, you could damage your chords by trying to hard.
That being said, I'll get to the real advice.
Essentially, you have three voices.
Chest, mix, head.
Chest is your lower powerful voice.
Mix is the balanced voice in between chest and head.. Think of chest voice as your bass voice, mix as your mid voice, and head as your treble voice.
Head, as I just stated, is your higher voice.. Not to be confused with falsetto, which doesn't even apply to girls.
Some things that helped so much would be:
1.Always try to stay on key and sing the exact same notes as the song you listen to.
It doesn't matter if you think you sound retarded, IT HELPS... As a Baritone/Tenor (I'm both), I expanded into Soprano by constantly singing Nick Pitera's A Whole New World as a joke.
2.Go some place as private as possible, and just try to belt out as strongly as possible.
Note, I said as strongly as possible.. That doesn't mean you should push yourself too hard.
Just sing at a regular volume, and slowly start singing more and more powerfully.
3.Try to learn and instrument, I'd suggest the piano.
Learning an instrument refines your ears... But also, it allows you to learn a little music theory.
4.Range is good, but being proficient in your true vocal range (for me it's Baritone and Tenor, though even I lean toward baritone a little more). If you are a Mezzosoprano, it's awesome if you can hit C6, or A2 on the lower end, but what you need to be proficient in, is your true range. Which, if you are a Mezzo, that would be A3-A5. Or if you are a Contralto (lowest female voice) E3-G5, and Soprano (highest) C4-C6.
All that being said, I have worked my way to a range of F2-D6, and after warm-ups, I can sometimes go from E2-F6 and occasionally G6. I hope you succeed as well!
Developing a deeper voice?
Q. Hello,
A lot of the people I know tell me I have a deep voice. That's great but I kinda want it to go a little deeper as the lowest note I can hit is D#3. Is it possible to go deeper than that? Is that even considered a deep voice? If so, what are some things I can do to maybe permanently lower the pitch of my voice?
A. your lower register tends to be more fixed than you upper register so there isn't really much you can do especially when you can go pretty low anyway which it sounds like you can (I'm assuming you mean Eb2 on a piano).
you can try a few things though. you can do exercises to strengthen your neck muscles as this means you vocal chords can be more relaxed and you will be able to go deeper more easily. you can also try singing very low and eventually you might improve at it. Also I've heard that death metal screaming/growling can extend your vocal range at both ends but I haven't tried it and I don't know if it damages your voice.
but really you can't expect to be able to get much deeper. maybe a few semitones at the most. Eb2 is already pretty low for a guy. most guys struggle to go below about E2 or F2 and higher pitched guys might not even be able to go below about G2 so your voice is already pretty deep.
