euclidean-rhythms

A micro-library in javascript that calculates the rhythmical patterns of equally distributed pulses in available steps. It implements the bjorklund's algorithm that is described by Godfried Toussaint in The Euclidean algorithm generates traditional musical rhythms

Purpose

I made this library in 2016; I couldn't find an implementation that yields to the expected results as described on the paper above and also being well tested with unit tests and code coverage.

The current solution is a javascript / typescript interpretation of the python code that is retrieved from atonalmicroshores.com

Usage

Node.js

Run npm install euclidean-rhythms

Then in your javascript / typescript code:

const er = require('euclidean-rhythms');

or in es6

import {getPattern} from 'euclidean-rhythms';

let cumbia = getPattern(3, 4);
cumbia should be [ 1, 0, 1, 1 ]

let cinquillo = getPattern(5, 8);
cinquillo should be [ 1, 0, 1, 1, 0, 1, 1, 0 ]

etc ...

Browser

** There is currently no umd bundle support from tsup, will be added as long as there is need for it; in the meantime you can use the older pre-typescript version of it.

Use one of the prepared browser bundles from unpkg.com
https://unpkg.com/euclidean-rhythms@2.0.1/dist/bundle.umd.js
https://unpkg.com/euclidean-rhythms@2.0.1/dist/bundle.umd.min.js

Then in your javascript code:

var pattern = euclideanRhythms.getPattern(5, 13);
pattern should be : [ 1, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 0, 0 ]

Develop

Clone the git repository and cd into it. Run npm run test for executing the unit tests and npm run build to build the ems, commonjs and iife bundles and the type definitions.
