Using matplotlib in the interest of music.

Musical Plots

This repo uses matplotlib to plot some cool things:

• Circle of Fifths: Can specify a root to highlight it's major key and the relative minor key.
• Hexes of Tenths (a structure made up by me): Can specify a root and an array of intervals which make up a chord or a scale.
• Fretboard: Can specify a root and an array of intervals which make up a chord or a scale. Can also specify fret count and string tuning.
• Keyboard: Can specify a root and an array of intervals which make up a chord or a scale. Can also specify number of octaves to display.

There is also a chord constructor in chords.py. You can give it an input such as "1-b3-5-b7" and it will create the necessary array of intervals, which is used by the actual plots.
