Dumb Fibonacci

This page presents a niche topic. While not arbitrary, it may contain ideas whose practical applications in music are unknown or narrow in scope. Niche topics are often developed by a single person or a small group. As such, this page may also contain idiosyncratic terms, notation, or conceptual frameworks.

The Dumb Fibonacci series is a subset of the overtone series: only the harmonics which are Fibonacci numbers. It begins:

[math]\displaystyle{ 1, 2, 3, 5, 8, 13, 21, 34, 55, 89... }[/math]

This like any harmonic series -like tuning, could be octave-reduced, and/or subsets of pitches could be taken to form scales.
