Fibonacci in Music


The first numbers in the Fibonacci sequence are 1, 2, 3, 5, 8, and 13. Music often uses these numbers.n

-In music, there is a scale of 8 notes, in which the 5th and 3rd notes create a chord.

-There is also a "third" which is produced when you play 1 note and then 2 notes above it.

-To play an Octave, you play 1 note and then 8 notes above it.

-In rock music, a power chord uses Triad chords 1, 3, and 5.

So, music uses the first six numbers in the Fibonacci sequence to create musical chords. These chords have been used throughout history and in all types of music. Without the Fibonacci sequence, basic patterns in music would not exist.

The Golden Ratio

The ratios pictured above all include the first 6 numbers in the Fibonacci sequence. They slowly get closer to the golden ratio, 1.618033988750. For example, the last ratio in the sequence is 8/5, which equals 1.6.


Many instruments use proportions that follow the Fibonacci sequence. This is used to create the best sound possible and to make every violin sound the same.


In conclusion, the Fibonacci sequence is very common in music and has greatly helped composers all over the world.
