Because were making iPod speakers in class, I decided to figure out the physics of music. First off, frequency is the amount of vibrations per second. Vibrations create sound. A through G are letters that are assigned to exact frequencies. For example, the note C has a wave length of 1.301. The reason there is no "H" note is because when frequencies double they sound similar due to the wave structure. When the notes repeat its called an octave. The black keys on the piano are notes that musicians had to make using relationship between frequency and vibrations per second. With the relationships from that equations, you can also discover the cords. The video on youtube "The Basic Physics of Music" goes into this with further detail. :-)
