shredderscales 1.0.4

Guitar-scales for any key and tuning

shredder-scales

shredder-scales is a python package that allows look-up of guitar scales given a key, scale, and tuning and outputs a plot showing the valid note positions on the fretboard.

The program accepts any number of guitar strings and any tuning without restriction to standard tunings. The number of guitar strings will be set based on the entered tuning.

For example:

• 'EADGBE' will set standard 6-string tuning
• 'G#D#G#C#F#A#D#' will set drop G# 7-string tuning
• 'F#BEADGBE' will set standard 8-string tuning

If a desired scale is not present in the library, custom scales can also be entered based on the intervals in the scale

Installation

Use the package manager pip for installation

pip install shredderscales
