NAME

Music::PitchNum::German - note name and pitch number roles for BACH

SYNOPSIS

  package MyCleverMozart;
  use Moo;
  with('Music::PitchNum::German');
  ...

Then elsewhere:

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

  $x->pitchname(70);      # b'
  $x->pitchname(69);      # a'
  $x->pitchname(72);      # c''
  $x->pitchname(71);      # h'

  $x->pitchnum(q{aes'});  # 68
  $x->pitchnum(q{g'});    # 67
  $x->pitchnum(q{b'});    # 70
  $x->pitchnum(q{a'});    # 69

  $x->ignore_octaves(1);
  $x->pitchname(72);      # c
  $x->pitchname(71);      # h

DESCRIPTION

A Music::PitchNum implementation specifically for BACH, whereby H represents what other systems term B natural and B represents B flat. Otherwise, the implementation is Helmholtz-based, or the one typically seen in lilypond, with accidentals in the Dutch or German style (es, is), and octave indications using , and '.

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

ATTRIBUTES

Just one, ignore_octave which if true (false by default) will cause calls to pitchname to omit the octave indication and return just a plain note.

METHODS

pitchname pitchnumber

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

pitchnum pitchname

Returns the pitch number for the given note name, or undef if the note could not be parsed. Note that the parser is quite permissive, see "Known Issues".

BUGS

Reporting Bugs

Please report any bugs or feature requests to bug-music-pitchnum at rt.cpan.org, or through the web interface at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Music-PitchNum.

Patches might best be applied towards:

https://github.com/thrig/Music-PitchNum

Known Issues

The parser is too lax, in that it will parse invalid input such as cses''' as pitch number 48 on account of the leading c.
