NAME

POE::Framework::MIDI::Key

DESCRIPTION

This package provides a lexicon of key types (major, minor, etc) and an interval key for building them from a root note. For example: consider a piano keyboard. The space from any note to its next nearest neighbour might be a black key or a white key. That's a semitone. Two semitones, or the key next to the key's nearest neighbour is a Tone (or ``Full Tone''). If you start on any key, and count up one semitone at a time, you get an ascending chromatic (play every semitone) scale. If you count ``Tone, Tone, Semitone, Tone, Tone, Tone, Semitone'' from the starting note, you get a major scale. This module aims to provide easy calculations for things like ``What's the third note in a major scale starting with C#?''

USAGE

my $key = new POE::Framework::MIDI::Key({ name => 'maj', root => 'E4' }); print ``The third of that scale is '', ${$key->numeric_scale}[2],``\n'';
