Overtone Scale

This category of instrument is referred to as the Overtone or Harmonic Scale.  The basis for this scale is the fundamental (lowest starting pitch) multiplied by its harmonic position out to 16 places.  For example, if the fundamental frequency is 100Hz and is multiplied by its 2nd harmonic (100 x 2) then the resulting frequency would be 200Hz.  Repeat the process by its 3rd, 4th, 5th etc. the harmonic pitches could conceivably go on out to infinity.  This means, as the pitches go higher the distance between them gets closer and closer.  

In the music scale below the starting pitch is bass or cello C (65.4Hz) and its harmonics only go out 16 places.


Note:  The "C" unisons are represented by the red circles around pitches 1, 2, 4, 8, and 16 and the marker dots in the middle of the bar.
