To learn a certain scale may not be that difficult but then to transpose it to another key

can be a bit of a struggle; every individual tone to a new value; then find those on the

harmonica; web search; paper and pen and lost notes…

HarmonicaScaler is powerful and makes the process easier and it’s very visual as well.

The chromatic scale consists of 12 tones: C, C♯, D, E♭, E, F, F♯, G, A♭, A, B♭, B

Scales over one harmonica

Even though the diatonic harmonica is designed to play in a single key; all the twelve chromatic tones can be played; and can be used to build scales up on. In other words: One scale can be played in 12 different keys on one harmonica. HarmonicaScaler works with 22 different scales. So over twelve keys the possible number of scales that can be displayed are:

22 scales x 12 keys = 264 scales

Scales over twelve harmonicas

For every tone in the chromatic scale it exists a harmonica in that key. So over twelve harmonicas the possible number of scales that can be displayed are:

22 scales x 12 keys x 12 harmonicas = 3168 scales
