Title: MusicXML


1
MusicXML
Music 253 / CS 275A Stanford University Winter
2005 Craig Stuart Sapp

Purpose
  • Primary function of MusicXML is data
    interchange between programs
  • Designed for encoding common-practice western
    music notation.

3
Predecessor Data Formats
  • MIDI
  • NIFF

not designed as a notation interchange format.
  • SmartScore

http//www.musitek.com/midiedition.html
  • Originally the only way out of Finales
    proprietary format.

formats.htmlNIFF
  • Available in Sibelius and Lime Notation Programs

see http//www.visiv.co.uk/niff.htm

MusicXML Development
  • Integration of MuseData format with Finale
    Typesetting Program

We have tried to learn from the mistakes of past
music notation interchange efforts by 1) basing
the format on the two strongest academic formats
available, MuseData and Humdrum, and 2) testing
the format by writing usable software from the
beginning of the development process.

  • June 2001 Alpha version of MusicXML 0.3
    available
  • March 2002 First commercial release of MusicXML
    0.6 (Import plugin comes with Finale 2003)
  • Jan 2004 MusicXML 1.0 released
  • Currently MusicXML 2.0 under development

rtwisegt
  • partwise score most common
  • each part listed serially
  • part consists of measures
  • measures contain (1) ltnotegts (items with
    duration) and
  • (2) ltattributegts (items without duration such as
    clef, time signature, key signature, etc.)
  • (3) ltdirectiongts (dynamics)
  • (4) ltsound/gt (tempo)

MuseData vs. MusicXML
  • MusicXMLs basic structure is a
    key-parameterized version of MuseData.

Causality
  • MusicXML is not a causal encoding format

ltbackupgt and ltforwardgt commands are used to
encode single parts with multiple staves or
multiple voices.
Examples of causal music formats MIDI
(partwise encoding) Humdrum (scorewise
encoding)
