harptool

Harptool is a simple CLI tool that prints note layouts for diatonic harmonicas in a variety of tunings, in any key. You can easily add your own tunings if you're missing any.

Harptool defaults to richter tuning and key of C if you do not specify.

features

print scale degrees instead of note names

harptool --degrees

specify harmonica key

harptool --key Bb

specify a different tuning

harptool --tuning wilde

colorize notes belonging to a scale

harptool --scale minor_pentatonic

specify a different position (1st position is default). Affects scale notes (--scale) and scale degrees (--degrees).

# highlight the 2nd position blues scale (C harp played in G)
harptool --scale blues --position 2

adding a custom tuning

Simply add a file in ~/.config/harptool/ with the note layout for your tuning. Separate notes by spaces, use capitals for notes and do not mix sharps and flats. You can use any key for this (it does not need to be C).

example for natural minor tuning:

C Eb G C Eb G C Eb G C
D G Bb D F A Bb D F A
