About

• Create Notes, Chords, Scales and more easily.
• Designed to be simple and intuitive.
• Easily integrate with other music libraries to play music in the browser - You can use libraries like ToneJS to easily play scales, chords and even scores you create with Note-Art.
• Use this library to create tools for musicians, research music theory, just create some fun music with programming and much more!

Features

1. Transpose, generate chords and scales easily, invert chords.
2. Tons of music theory utilities, e.g getting the interval between 2 notes, normalizing notes, getting the enharmonic pitch class, converting sharps to flats and a lot more.

Getting Started

Installation:

# Using npm
npm install note-art

# Using yarn
yarn add note-art

Usage

Note-art is fully written in TS and offers functions that can achieve any music theory related task you desire.

Theory Functions

• patterns are in semi-tones.

Transpose any pitch class, note or group of notes easily

import { transpose } from 'note-art'

// PitchClass

transpose('A', 5)  // 'D'

// Note

transpose('A3', 5)  // 'D4'

// Group of notes(can represent a chord, scale or anything else)

const notes = ['C3', 'E3', 'G3']

notes.map(note => transpose(note, 7)) // ['G3', 'B3', 'D4'] 

Other functions

import { noteFromFrequency, intervalsToNotes, invertChord };

noteFromFrequency(440) // A4

const majorChordPattern = [0, 4, 7];
const cMajorChord = intervalsToNotes('C3', majorChordPattern) // ['C3', 'E3', 'G3']

const cMajorFirstInversion = invertChord(cMajorChord, 1); // ['E3', 'G3', 'C4']
