Visualising Notes

AutoMuse comes with utilities that visualise notes on a fretboard. These can be found in automuse.guitar.

First, let’s draw an empty fretboard.

from automuse.guitar import draw_scale

draw_scale([], capo=0, width=13)

Then, let’s draw a fretboard with all the notes. Sorry but I have ran out of transitional words.

from automuse.guitar import draw_scale

draw_scale(list(automuse.NOTES), capo=0, width=15)

Let’s visualise some notes next. By default, the visualiser shows all notes in the same class – for example, drawing \(C_5\) draws \(C_4\) and \(C_6\) as well. You can change it with an option, but please bear with the tutorial for now.

draw_scale(chord.seventh("C5", modes.MAJOR_BLUES), 0, 20)

Try a blues triad next!

draw_scale(chord.chord("C5", modes.MAJOR_BLUES), 0, 20)

Strict Mode

To only draw notes on specific octaves, use strict=True.

Up to the 12th fret, the guitar can play notes from E4 (52 in the MIDI standard) to E7 (88 in the MIDI standard), so let’s try the \(C_5\) major.

draw_scale(chord.chord("C5", modes.MAJOR), 0, 15, strict=True)
