This sequence is the number of semitones away from the root tone on a ten-hole diatonic harmonica in standard Richter tone layout. On each hole the player can blow or draw air. Here n=1 is hole 1 blow, n=2 is hole 1 draw, n=3 is hole 2 blow, n=4 is hole 2 draw, ...

The sequence does not account for tones that can be produced by the bending technique.

The sequence can be used to compute the tone layout of a ten-hole diatonic harmonica in standard Richter tone layout in different keys, i.e., with different root tone.


Table of n, a(n) for n=1..20.
