VERSION
version 0.0200
SYNOPSIS
use Music::MelodicDevice::Ornamentation;
# Chromatic
my $md = Music::MelodicDevice::Ornamentation->new;
my $spec = $md->grace_note('qn', 'D5', 1); # [[xn D#5], [d90 D5]]
$spec = $md->turn('qn', 'D5', 1); # [[sn D#5], [sn D5], [sn C#5], [sn D5]]
$spec = $md->trill('qn', 'D5', 2, 1); # [[sn D#5], [sn D5], [sn D#5], [sn D5]]
$spec = $md->mordent('qn', 'D5', 1); # [[yn D5], [yn D#5], [den D5]]
# Diatonic
$md = Music::MelodicDevice::Ornamentation->new(scale_name => 'major');
$spec = $md->grace_note('qn', 'D5', 1); # [[xn E5], [d90 D5]]
$spec = $md->turn('qn', 'D5', 1); # [[sn E5], [sn D5], [sn C5], [sn D5]]
$spec = $md->trill('qn', 'D5', 2, 1); # [[sn E5], [sn D5], [sn E5], [sn D5]]
$spec = $md->mordent('qn', 'D5', 1); # [[yn D5], [yn E5], [den D5]]
DESCRIPTION
Music::MelodicDevice::Ornamentation
provides chromatic and diatonic musical ornamentation methods.
The duration part of the returned note specifications is actually in MIDI::Simple d###
style, even though the SYNOPSIS shows them as MIDI::Simple and Music::Durations abbreviations. This is for conceptual reasons only.
ATTRIBUTES
scale_note
Default: C
scale_name
Default: chromatic
For the chromatic scale, enharmonic notes are listed as sharps. For a scale with flats, a diatonic scale_name must be used with a flat scale_note.
Please see "SCALES" in Music::Scales for a list of valid scale names.
verbose
Default: 0
METHODS
new
$x = Music::MelodicDevice::Ornamentation->new(
scale_note => $scale_note,
scale_name => $scale_name,
verbose => $verbose,
);
Create a new Music::MelodicDevice::Ornamentation
object.
grace_note
$spec = $md->grace_note($duration, $pitch, $offset);
"Appoggiatura" means emphasis on the grace note. "Acciaccatura" means emphasis on the main note. This module doesn't accent notes. You'll have to do that bit.
turn
$spec = $md->turn($duration, $pitch, $direction);
The note Above, the Principle note (the pitch), the note Below, the Principle note again.
The default direction is 1
, but if given as -1
, the turn is "inverted" and goes: Below, Principle, Above, Principle.
trill
$spec = $md->trill($duration, $pitch, $number, $offset);
A trill is a number of pairs of notes spread over a given duration. The first of the pair being the given pitch and the second one given by the offset.
mordent
$spec = $md->mordent($duration, $pitch, $offset);
"A rapid alternation between an indicated note [the pitch], the note above or below, and the indicated note again."
So if the pitch is D5
, a diatonic upper mordent would be D5-E5-D5
. A chromatic lower mordent would be D5-C#5-D5
.
