NAME
Music::Dataset::ChordProgressions - Provide access to hundreds of chord progressions
VERSION
version 0.0400
SYNOPSIS
use Music::Dataset::ChordProgressions qw(as_file as_list as_hash transpose);
my $filename = as_file();
my @data = as_list();
my %data = as_hash();
my $transposed = transpose('A', 'major', 'C-F-Am-F');DESCRIPTION
Music::Dataset::ChordProgressions provides access to hundreds of musical chord progressions in five genres: blues, country, jazz, pop and rock. Each has progressions in keys of C major and C minor.
Each of these is divided into a named type of progression. Take these types with a grain of salt. They may or may not be meaningful...
The named chords are meant to match the known chords of Music::Chord::Note (listed in the source of that module).
There are a few odd chord "progressions" like "Eb7-Eb7-Eb7-Eb7","III-III-III-III". Strange...
I stumbled across this list, saved it on my hard-drive for a long time, and then forgot where it came from! Also the documentation in the original list said nothing about who made it or how. :\

$filename = as_file();Return the chord progression data filename location.
as_list
