Standard Music Font Layout

  1. 1. Standard Music Font LayoutMusic Encoding Conference23 May 2013Daniel Spreadbury
  2. 2. A brief history of music fonts• First commercial music font was Sonata from Adobe in1985• Features 176 glyphs• Organised mnemonically on a Latin keyboard (e.g. q =quarter note)• Became de facto standard for mapping of music fonts• Most music fonts since have used largely Sonata-compatible layouts, e.g. Petrucci (Finale, 1988), Opus(Sibelius, 1993)
  3. 3. A brief history of music fonts• Perry Roland proposed range of musicalsymbols for Unicode in 1998• Range was approved, with 220 glyphs• To date, no font has completely implementedthe range• Only commercial font with a partialimplementation is Adobe Sonata Std,OpenType update to original Sonata font
  4. 4. Problems to be solved• Sonata’s 170 glyphs are insufficient for thebreadth of symbols used in CMN• No agreement on how to expand beyondSonata’s initial set, hence rapiddivergence…
  5. 5. Sonata: a standard?Sonata
  6. 6. Sonata: a standard?Petrucci
  7. 7. Sonata: a standard?Opus
  8. 8. Sonata: a standard?Sonata, compared with Opus and Petrucci (all agree; S & P agree; O & P agree)
  9. 9. Problems to be solved• Existing Unicode Musical Symbols rangeis also insufficiently broad• Some scoring applications cannot in anycase access code points beyond UnicodePlane 0• Lack of a real standard makes sharingmusic fonts between applications difficult
  10. 10. So… what is SMuFL?• A standard way of mapping musicalsymbols to the Private Use Area of theBasic Multilingual Plane in Unicode• A set of technical guidelines for how musicfonts should be built
  11. 11. Goals• ExtensibleProvide a framework that makes itconvenient for additional characters to beadded• Build a communityDraw on scholarly expertise to minimiseerrors and omissions
  12. 12. Goals• Open licenseRemove any impediments to fontdevelopers and application vendorsadopting SMuFL• Practical and usefulDesigned with real-world use in mind
  13. 13. Non-goals• Not currently targeting ratification by the UnicodeConsortium– What to do with the existing Musical Symbols range?– Some characters are duplicated from other ranges forconvenience; unlikely to be accepted by theConsortium• Not targeting use in text-based applications– Although many characters could be usefully used, it’simpractical for end users to type characters from thePUA anyway
  14. 14. What’s included• 59 discrete sub-ranges of symbols• 808 symbols and counting!• Includes all 220 glyphs from the UnicodeMusical Symbols range• Room for expansion by leaving emptycode points between ranges
  15. 15. What’s included
  16. 16. Methodology• Started with Unicode Musical Symbols range• Reviewed existing fonts (Sonata, Opus, Petrucci,Emmentaler, etc.) and categorised additional sub-ranges andsymbols• Reviewed the standard music notation texts (Gould, Read,Stone, etc.)• Reviewed specialist literature (e.g. Ghent conference forpercussion, Salzedo for harp, handbells, accordion, functionsymbols, etc.)• Shared proposals with small group of expert music engraversand editors
  17. 17. Open license• Released under MIT license• Steinberg retains copyright, but free foranybody to use, modify, create derivativeversions, sell, etc.• ...but we hope to build a communityfocused around contributing todevelopment of SMuFL rather than to seeefforts splinter
  18. 18. Next steps• Establish a governance model to manageproposed changes and additions• Fill any identified gaps• Define mappings for common music fonts toSMuFL to determine coverage in existingfonts• Encourage the development of furtherSMuFL-compliant fonts
  19. 19. Bravura
  20. 20. Bravura• The first SMuFL-compliant font• Includes all SMuFL characters, and (almost) allUnicode Musical Symbols characters• Released under the SIL Open Font License– Free to use, bundle, embed, create derivativeversions, etc.– Only licensing restrictions are that the font cannot besold on its own; derivative versions cannot use thesame name; and derivative versions must bereleased under the same licensing terms
