SYNOPSIS

  use Music::ScaleNote;
  use Music::Note;
  my $msn = Music::ScaleNote->new(
    scale_note => 'C',
    scale_name => 'pminor',
    verbose    => 1,
  );
  my $note = $msn->get_offset(
    note_name   => 'C4',
    note_format => 'ISO',
    offset      => 1,
  );
  print $note->format('ISO'), "\n"; # D#4

DESCRIPTION

A Music::ScaleNote object manipulates the position of a note in a scale.

Given a scale, a starting note, a scale note, and a scale position offset, this module computes the new note.

So for scale C D# F G A# (C pentatonic minor), note C4, and offset 1 (move one note to the right), this module will return D#4.

For offset -1, A#3 is returned.

ATTRIBUTES

Default: C

scale_name

Please see "SCALES" in Music::Scales for the possible names.

offset

The integer offset of a new scale position. If given in the constructor, this is used as the default in the get_offset method.

verbose

Show the progress of the get_offset method.

  $msn = Music::ScaleNote->new(%arguments);
