chordparser 0.2.0

Parse and analyse chords

A simple Python 3 package to analyse chords.

chordparser aims to parse chord notation and provide harmonic analysis of chords based on keys and scales. This helps in understanding how each chord functions, and allows for the conversion to roman numeral chord notation.

The parser can be used to analyse the following chords: diatonic chords, mode mixture/ borrowed chords (from other modes), secondary dominant chords (e.g. V/V), secondary leading tone chords.
