Musical Rhythms with Math in Perl

Furnished content.

Let’s talk about music programming! There are a million aspects to this subject, but today, we’ll touch on generating rhythmic patterns with mathematical and combinatorial techniques. These include the generation of partitions, necklaces, and Euclidean patterns.Stefan and J. Richard Hollos wrote an excellent little book called “Creating Rhythms” that has been turned into C, Perl, and Python. It features a number of algorithms that produce or modify lists of numbers or bit-vectors (of ones and zeroes). These can be beat onsets (the ones) and rests (the zeroes) of a rhythm. We’ll check out these concepts with Perl.For each example, we’ll save the MIDI with the MIDI::Util module. Also, in order to actually hear the rhythms, we will need a MIDI synthesizer. For these illustrations, fluidsynth will work. Of course, any MIDI capable synth will do! I often control my eurorack analog synthesizer with code (and a MIDI interface module).Here’s how I start fluidsynth on my mac in the terminal, in a separate session. It uses a generic soundfont file (sf2) that can be downloaded here (124MB zip).

fluidsynth -a coreaudio -m coremidi -g 2.0 ~/Music/soundfont/FluidR3_GM.sf2

So, how does Perl know what output port to use? There are a few ways, but with JBARRETT’s MIDI::RtMidi::FFI::Device, you can do this:

use MIDI::RtMidi::FFI::Device ();my  = RtMidiIn->new;my  = RtMidiOut->new;print "Input devices:\n";->print_ports;print "\n";print "Output devices:\n";->print_ports;print "\n";

This shows that fluidsynth is alive and ready for interaction.Okay, on with the show!First-up, let’s look at partition algorithms. With the part() function, we can generate all partitions of n, where n is 5, and the “parts” all add up to 5. Then taking one of these (say, the third element), we convert it to a binary sequence that can be interpreted as a rhythmic phrase, and play it 4 times.

#!/usr/bin/env perluse strict;use warnings;use Music::CreatingRhythms ();my  = Music::CreatingRhythms->new;my  = ->part(5);# [ [ 1, 1, 1, 1, 1 ], [ 1, 1, 1, 2 ], [ 1, 2, 2 ], [ 1, 1, 3 ], [ 2, 3 ], [ 1, 4 ], [ 5 ] ]my $p = ->[2]; # [ 1, 2, 2 ]my  = ->int2b([$p]); # [ [ 1, 1, 0, 1, 0 ] ]

Now we render and save the rhythm:

use MIDI::Util qw(setup_score);my  = setup_score(bpm => 120, channel => 9);for (1 .. 4) {    for my  (->[0]->@*) {        if () {            ->n('en', 40);        }        else {            ->r('en');        }    }}->write_score('perldotcom-1.mid');

In order to play the MIDI file that is produced, we can use fluidsynth like this:

fluidsynth -i ~/Music/soundfont/FluidR3_GM.sf2 perldotcom-1.mid

Your browser does not support the audio element.Not terribly exciting yet.Let’s see what the “compositions” of a number reveal. According to the Music::CreatingRhythms docs, a composition of a number is “the set of combinatorial variations of the partitions of n with the duplicates removed.”Okay. Well, the 7 partitions of 5 are:

[[1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 1, 3], [1, 2, 2], [1, 4], [2, 3], [5]]

And the 16 compositions of 5 are:

[[1, 1, 1, 1, 1], [1, 1, 1, 2], [1, 1, 2, 1], [1, 1, 3], [1, 2, 1, 1], [1, 2, 2], [1, 3, 1], [1, 4], [2, 1, 1, 1], [2, 1, 2], [2, 2, 1], [2, 3], [3, 1, 1], [3, 2], [4, 1], [5]]

That is, the list of compositions has, not only the partition [1, 2, 2], but also its variations: [2, 1, 2] and [2, 2, 1]. Same with the other partitions. Selections from this list will produce possibly cool rhythms.Here are the compositions of 5 turned into sequences, played by a snare drum, and written to the disk:

use Music::CreatingRhythms ();use MIDI::Util qw(setup_score);my  = Music::CreatingRhythms->new;my  = ->compm(5, 3); # compositions of 5 with 3 elementsmy  = ->int2b();my  = setup_score(bpm => 120, channel => 9);for my  (->@*) {    for my  (@) {        if () {            ->n('en', 40); # snare patch        }        else {            ->r('en');        }    }}->write_score('perldotcom-2.mid');

Your browser does not support the audio element.A little better. Like a syncopated snare solo.Another way to play the MIDI file is to use timidity. On my mac, with the soundfont specified in the timidity.cfg configuration file, this would be:

timidity -c ~/timidity.cfg -Od perldotcom-2.mid

To convert a MIDI file to an mp3 (or other audio formats), I do this:

timidity -c ~/timidity.cfg perldotcom-2.mid -Ow -o - | ffmpeg -i - -acodec libmp3lame -ab 64k perldotcom-2.mp3

Okay. Enough technical details! What if we want a kick bass drum and hi-hat cymbals, too? Refactor time

use MIDI::Util qw(setup_score);use Music::CreatingRhythms ();my  = Music::CreatingRhythms->new;my  = ->compm(4, 2); # snaremy  = ->int2b();my  = ->compm(4, 3); # kickmy  = ->int2b();my  = setup_score(bpm => 120, channel => 9);for (1 .. 8) { # repeats    my  = ->[ int rand @ ];    my  = ->[ int rand @ ];    for my $i (0 .. $#) { # pattern position        my @notes = (42); # hi-hat every time        if (->[$i]) {            push @notes, 40;        }        if (->[$i]) {            push @notes, 36;        }        ->n('en', @notes);    }}->write_score('perldotcom-3.mid');

Your browser does not support the audio element.Here we play generated kick and snare patterns, along with a steady hi-hat.Next up, let’s look at rhythmic “necklaces.” Here we find many grooves of the world.Image from The Geometry of Musical RhythmRhythm necklaces are circular diagrams of equally spaced, connected nodes. A necklace is a lexicographical ordering with no rotational duplicates. For instance, the necklaces of 3 beats are [[1, 1, 1], [1, 1, 0], [1, 0, 0], [0, 0, 0]]. Notice that there is no [1, 0, 1] or [0, 1, 1]. Also, there are no rotated versions of [1, 0, 0], either.So, how many 16 beat rhythm necklaces are there?

my  = ->neck(16);print scalar @, "\n"; # 4116 of 'em!

Okay. Let’s generate necklaces of 8 instead, pull a random choice, and play the pattern with a percussion instrument.

use MIDI::Util qw(setup_score);use Music::CreatingRhythms ();my  = shift || 75; # clavesmy  = Music::CreatingRhythms->new;my  = ->neck(8);my  = ->[ int rand @ ];my  = setup_score(bpm => 120, channel => 9);for (1 .. 4) { # repeats    for my  (@) { # pattern position        if () {            ->n('en', );        }        else {            ->r('en');        }    }}->write_score('perldotcom-4.mid');

Your browser does not support the audio element.Here we choose from all necklaces. But note that this also includes the sequence with all ones and the sequence with all zeroes. More sophisticated code might skip these.More interesting would be playing simultaneous beats.

use MIDI::Util qw(setup_score);use Music::CreatingRhythms ();my  = Music::CreatingRhythms->new;my  = ->neck(8);my  = ->[ int rand @ ];my  = ->[ int rand @ ];my  = ->[ int rand @ ];my  = setup_score(bpm => 120, channel => 9);for (1 .. 4) { # repeats    for my $i (0 .. $#) { # pattern position        my @notes;        if (->[$i]) {            push @notes, 75; # claves        }        if (->[$i]) {            push @notes, 63; # hi_conga        }        if (->[$i]) {            push @notes, 64; # low_conga        }        ->n('en', @notes);    }}->write_score('perldotcom-5.mid');

And that sounds like: Your browser does not support the audio element.How about Euclidean patterns? What are they, and why are they named for a geometer?Euclidean patterns are a set number of positions P that are filled with a number of beats Q that is less than or equal to P. They are named for Euclid because they are generated by applying the “Euclidean algorithm,” which was originally designed to find the greatest common divisor (GCD) of two numbers, to distribute musical beats as evenly as possible.

use MIDI::Util qw(setup_score);use Music::CreatingRhythms ();my  = Music::CreatingRhythms->new;my  = 16;my  = ->rotate_n(4, ->euclid(2, )); # snaremy  = ->euclid(2, ); # kickmy  = ->euclid(11, ); # hi-hatsmy  = setup_score(bpm => 120, channel => 9);for (1 .. 4) { # repeats    for my $i (0 ..  - 1) { # pattern position        my @notes;        if (->[$i]) {            push @notes, 40; # snare        }        if (->[$i]) {            push @notes, 36; # kick        }        if (->[$i]) {            push @notes, 42; # hi-hats        }        if (@notes) {            ->n('en', @notes);        }        else {            ->r('en');        }    }}->write_score('perldotcom-6.mid');

Your browser does not support the audio element.Now we’re talkin’ - an actual drum groove! To reiterate, the euclid() method distributes a number of beats, like 2 or 11, over the number of beats, 16. The kick and snare use the same arguments, but the snare pattern is rotated by 4 beats, so that they alternate.

So what have we learned today?

That you can use mathematical functions to generate sequences to represent rhythmic patterns.
That you can play an entire sequence or simultaneous notes with MIDI.
