A parser and type definition set for MusicXML.

MusicXML Interfaces

musicxml-interfaces is a low-level JavaScript utility library for parsing, serializing, building, and patching MusicXML songs.

musicxml-interfaces does not provide users with utilities for rendering or analysing MusicXML songs. This project is used by Satie, which provides higher-level functionality.

Getting musicxml-interfaces

Use npm to install this package for node or browsers. For use with browsers, you'll also need to use a loader such as webpack.

npm install --save [email protected]

Usage

Example

Here is a simple example using ES6 or TypeScript:

import {parseScore, serializeScore} as MusicXML from 'musicxml-interfaces';
import 'whatwg-fetch';

fetch('/sonata.xml')
  .then(function(response) {
    return response.text()
  }).then(function(xml) {
    let document = parseScore(score);
    console.log('Converted XML to ', doc);

    let xml = serializeScore(doc);
    console.log('Converted JavaScript document to ', xml);
  });

Here is the same example, using ES5:

var MusicXML = require("musicxml-interfaces");
require("whatwg-fetch");

fetch('/sonata.xml')
  .then(function(response) {
    return response.text()
  }).then(function(xml) {
    let document = MusicXML.parseScore(score);
    console.log('Converted XML to ', doc);

    let xml = MusicXML.serializeScore(doc);
    console.log('Converted JavaScript document to ', xml);
  });

Parsing

    /**
     * Converts a MusicXML document into a MusicXML parttime-inspired JSON object.
     * See ScoreTimewise for full return type specification.
     *
     * This function will accept timepart MusicXML files, but will still return a
     * structure similar to parttime.
     */
    MusicXML.parseScore(score: string): MusicXMLScoreTimewise;

    /**
     * Reads a document, and returns header information.
     *
     * ScoreHeader is a subset of ScoreTimewise, so you can always just call MusicXML.parse.score.
     * This function is a bit faster though, if you only care about metadata.
     */
    MusicXML.paseScoreHeader(score: string): MusicXML.ScoreHeader;

    /**
     * Converts a MusicXML <measure /> from a **parttime** document into JSON.
     */
    MusicXML.parseMeasure(str: string): MusicXML.Measure;

    /**
     * These functions convert an XML string into corresponding JSON.
     */
    MusicXML.parseNote(str: string): MusicXML.Note;
    MusicXML.parseClef(str: string): MusicXML.Clef;
    MusicXML.parseTime(str: string): MusicXML.Time;
    MusicXML.parseKey(str: string): MusicXML.Key;
    MusicXML.parsePartSymbol(str: string): MusicXML.PartSymbol;
    MusicXML.parseBackup(str: string): MusicXML.Backup;
    MusicXML.parseHarmony(str: string): MusicXML.Harmony;
    MusicXML.parseForward(str: string): MusicXML.Forward;
    MusicXML.parsePrint(str: string): MusicXML.Print;
    MusicXML.parseFiguredBass(str: string): MusicXML.FiguredBass;
    MusicXML.parseDirection(str: string): MusicXML.Direction;
    MusicXML.parseAttributes(str: string): MusicXML.Attributes;
    MusicXML.parseSound(str: string): MusicXML.Sound;
    MusicXML.parseBarline(str: string): MusicXML.Barline;
    MusicXML.parseGrouping(str: string): MusicXML.Grouping;

Serializing

    /**
     * These functions convert a parsed JSON into corresponding MusicXML.
     */
    MusicXML.serializeScore(score: ScoreTimewise): string;
    MusicXML.serializeScoreHeader(scoreHeader: ScoreHeader): string;
    MusicXML.serializeMeasure(measure: Measure): string;
    MusicXML.serializeNote(note: Note): string;
    MusicXML.serializeClef(clef: Clef): string;
    MusicXML.serializeTime(time: Time): string;
    MusicXML.serializeKey(key: Key): string;
    MusicXML.serializePartSymbol(partSymbol: PartSymbol): string;
    MusicXML.serializeBackup(backup: Backup): string;
    MusicXML.serializeHarmony(harmony: Harmony): string;
    MusicXML.serializeForward(forward: Forward): string;
    MusicXML.serializePrint(print: Print): string;
    MusicXML.serializeFiguredBass(figuredBass: FiguredBass): string;
    MusicXML.serializeDirection(direction: Direction): string;
    MusicXML.serializeAttributes(attributes: Attributes): string;
    MusicXML.serializeSound(sound: Sound): string;
    MusicXML.serializeBarline(barline: Barline): string;
    MusicXML.serializeGrouping(grouping: Grouping): string;

Builders

musicxml-interfaces provides tools for building structures and JSON0 patches in musicxml-interfaces/builders. These should be considered expiremental.

Types / usage with TypeScript

There is a one-to-one mapping of MusicXML and the JSON produced by MusicXML Interfaces. The TypeScript defintion file fully documents MusicXML Interfaces types.

Contributing

Please report issues! In particular,

• If there is a discrepency between a DTD in vendor/musicxml-dtd and the TypeScript interfaces in index.d.ts, just state the discrepency.
• If the TypeScript interface definitions are correct, but there is an error in importing a file, provide a minimal MusicXML file that illustrates the issue.
• If there is an error in exporting MusicXML interfaces back to MusicXML, provide a minimal valid JSON structure that is not exported correctly.
