NAME

Music::PitchNum::ABC - note name and pitch number roles for ABC notation

SYNOPSIS

  package MyCleverMouse;
  use Moo;
  with('Music::PitchNum::ABC');
  ...

Then elsewhere:

  use MyCleverMouse;
  my $x = MyCleverMouse->new;

  $x->pitchname(69);    # A
  $x->pitchnum('A');    # 69

DESCRIPTION

A Music::PitchNum implementation specifically for the ABC notation, which varies from the other notation forms by using case sensitive letters to denote octave indications, otherwise falling back to the Helmholtz form outside the range around middle C (via , and ' marks). Oh, and the accidental notation is also totally different from the other forms.

This module is expected to be used as a Role from some other module; Moo::Role may be informative.

METHODS

pitchname pitchnumber

Returns the pitch name for the given integer, though will throw an exception if passed something that is not a number.

This method accepts an optional ignore_octave parameter that if true will strip the octave information from the pitch name.

pitchnum pitchname

Returns the pitch number for the given ABC note name, or undef if the note could not be parsed.
