Q. I'm pretty sure that math is related to music... I just don't know how... Please help?
A. More with Physics and Math actually.
Take the piano for example, the wavelength of each of the strings plays a different sound when it is shorten or lengthen. It uses the characteristics of fractions.
Violins, Guitars, and pretty much any string instruments.
Instruments like Flutes make use of the resonance effect of sound waves.
Also, here is a question related to yours, it is about Math and playing chords (I was chosen as Best Answer) http://ca.answers.yahoo.com/question/index;_ylt=Ardvruq0Oh2ek3A5LDe4_fnAFQx.;_ylv=3?qid=20091218225212AAMbH0A&show=7#profile-info-JQsvHyfjaa
In Physics we have a formula for calculating "Beats" in Hz. It goes as Fbeat = l f1 - f2 l. If f1 and f2 are the same, then we do not get a beat. l...l are absolute value signs
How to write an Intro for a song on piano?
Q. Okay I wrote a song on piano, and I wish I could upload it but i have no recording gear. Its just the melody, chords, and lyrics right now. I want some intro and outro music. Any advice on these?
I used F2, F, Em, and G chords.
A. if F2 is the first chord, that is your goal chord for the intro.
that means the chord before it could be something like V/F2
http://www.musictheory.halifax.ns.ca/26secondarydominants.html
before that you could have chords in the key of that dominant, or use the secondary dominant of that.
to make the intro really lead, make sure to follow the voice leading rules!

the outro, just use your ear to figure out what sounds good next, and follow the rules, or it won't be as strong.
why don't we hear beats when different keys on the piano are played at the same time?
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,
