NAME

MIDI::Bassline::Walk - Generate walking basslines

VERSION

version 0.0103

SYNOPSIS

use MIDI::Bassline::Walk;

my $bassline = MIDI::Bassline::Walk->new(verbose => 1);

my $notes = $bassline->generate('C7b5', 8);

# MIDI:
# $score->n('qn', $_) for @$notes;

DESCRIPTION

MIDI::Bassline::Walk generates randomized, walking basslines.

The logic (and music theory) implemented here, can generate some sour notes. And sometimes too much! This is an approximate composition tool, and not a drop-in bass player. Import the rendered MIDI into a DAW and alter things until they are suitable.

The chords recognized by this module, are those known by Music::Chord::Note. Please see the source of that module for the list.
