Music::ChordBot - Programmatically build songs for ChordBot


Song API (simple):

  use Music::ChordBot::Song;

  # Define a song
  song "Funky Perl";
  tempo 120;

  # Define a section (song part)
  section "Funky Section";
  style "Kubiac";

  # Add chords.
  Dm7 4; Am7; Dm7; Dm7;

Song API (explicit chords):

  # Add chords.
  chord "D Min7 4";
  chord "A Min7 4";
  chord "D Min7 4";
  chord "D Min7 4";

Opus API (powerful):

  use Music::ChordBot::Opus;
  use Music::ChordBot::Opus::Section;

  # The song.
  my $song = Music::ChordBot::Opus->new(
      name => "Funky Perl", tempo => 120 );

  # One section.
  my $section = Music::ChordBot::Opus::Section->new(
      name => "Funky Section" );

  $section->set_style( "Kubiac" );
  $section->add_chord( "D Min7 4" );
  $section->add_chord( "A Min7 4" );
  $section->add_chord( "D Min7 4" );
  $section->add_chord( "D Min7 4" );

  # Add section to song.

  # Export as json.
  print $song->json, "\n";


Chordbot is a songwriting tool / electronic backup band for
iPhone/iPad and Android that lets you experiment with advanced chord
progressions and arrangements quickly and easily. You can use Chordbot
for songwriting experiments, as accompaniment when learning new songs
or for making backing tracks for your guitar / saxophone / theremin

ChordBot can import and export songs in JSON format. Music::ChordBot
provides a set of modules that can be used to programmatically
build songs and produce the JSON data suitable for import into

ChordBot web site: L<http://www.chordbot.com>.

Note that Music::ChordBot requires the full version of ChordBot since
the Lite version does not have import capabilities.

Currently there are two distinct API's as can be seen from the
SYNOPSYS. See L<Music::ChordBot::Song> and L<Music::ChordBot::Opus>
for details.
