Installation

Install using:

pip install scales.py

Then import it like so:

from scales import Scales

Usage

Scales objects take at least the scale parameter, which should be a list of notes (the first note is treated as the root). They can be drawn using the draw function, where start and stop are the range of frets to show (defaults to showing 15 frets if not specified).

For example:

a_mixo = ['A', 'B', 'C#', 'D', 'E', 'F#', 'G']
six_string = Scales(title='A Mixolydian', scale=a_mixo)
six_string.draw(start=11, stop=15)

By default, it will assume a 6 string guitar in standard tuning, but you can specify other tunings like:

c_major = ['C', 'D', 'E', 'F', 'G', 'A', 'B']
ukulele = Scales(title='C Major on Ukulele', strings=['G', 'C', 'E', 'A'], scale=c_major)
ukulele.draw()

Scales can be drawn without making it an object:

g_chord = ['G', 'B', 'D']
Scales(title='Open G', scale=g_chord).draw(stop=3)

Other helpful uses

Scales can be used to generate blank visuals to print out. Heres a blank 6 string fretboard:

Scales([]).draw()

Or a blank open chord chart:

Scales([]).draw(stop=3)
