We have only touched the tip of the iceberg on the topic of music and math. On the surface, there seems to be a perfectly harmonious relationship between these two disciplines. In fact, the reality is much more complicated. Take tone for example, usually the first harmonic is the strongest. But with the bass notes of a piano, the first harmonic is weaker than the other harmonics. We have to find a way to redefine pitch in these cases (Giordano, 2010). While timbre has a lot to do with harmonics, other factors are also involved. We know the string of a violin sounds differently when it is bowed than plucked. This is due to the result of the attack, or how the sound is produced (Parker, 2009). There is also another problem with the Pythagorean scale. The Pythagorean scale is based on octaves and fifths. If we keep multiplying fifths, we should expect to come back to C and C'. But this is not the case. The result of 1.5 x 1.5 x 1.5 x1.5 x 1.5 x ...x 1.5 will never be a multiple of 2. Then we have to either give up either pure octaves or pure fifths. Later an equal tempered scale was devised to solve this issue (Giordano, 2010).
