Fibonacci being represented in music is mostly shown in scales. Octave is made of 12 chromatic tones. Plus, one the octave. A scale is composed of eight notes. The fifth and third notes create a basic fondation of chords, based off of the whole tones that is two steps above root tones, which is the first note of the scale. Fibonacci is related to music because as Pythagoras stated the ratio portrayed is most pleasing to the ear. The numbers of Fibonacci when divided show frequency that most notes and octaves are based off. A more clear demonstration is shown on the design of a piano.
