Music::PitchNum::ASPN - note name and pitch number roles for ASPN notation
package MyCleverMod; use Moo; with('Music::PitchNum::ASPN'); ...
use MyCleverMod; my $x = MyCleverMod->new; $x->pitchname(69); # A4 $x->pitchname(70); # A#4 $x->pitchnum('A'); # 69 $x->pitchnum('A#'); # 70 $x->pitchname(69, ignore_octave => 1); # A
A Music::PitchNum implementation specifically for the American Standard Pitch Notation (ASPN), also known as the scientific notation.
This module is expected to be used as a Role from some other module; Moo::Role may be informative.
- 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 ASPN note name, or
undefif the note could not be parsed. Only the note names
A-G(and not the lower case forms), optional
#for sharp, and the octave number are parsed by this module; other forms will (or should) not match.
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:
None known for the ASPN notation support, though this is a very limited format with only one accidental style (a single
# for sharp) and a mandatory octave number.
