1.Standard Music Font Layout MusicXML community meeting 14 March 2014 Daniel Spreadbury

2. A brief history of music fonts First commercial music font was Sonata from Adobe in 1985, with 176 glyphs, organised mnemonically for a Latin keyboard Became de facto standard for mapping of most music fonts: e.g. Petrucci (Finale, 1988), Opus (Sibelius, 1993) Range of 220 musical symbols was added to Unicode in 1998; to date, no font has completely implemented this Unicode range 3. Problems to be solved Lack of a real standard makes sharing music fonts between applications difficult Sonatas 170 glyphs and Unicodes 220 glyphs are insufficiently broad in scope No agreement on how to expand beyond these initial sets 4. What is SMuFL? A standard way of mapping musical symbols to the Private Use Area of the Basic Multilingual Plane in Unicode A set of technical guidelines for how music fonts should be designed and built Simple JSON metadata formats to help applications use SMuFL fonts easily Released under MIT license, free to use/modify 5. Whats included 108 discrete sub-ranges of glyphs 2554 glyphs and counting! Includes all 220 glyphs from the Unicode Musical Symbols range Also includes recommendations for ligatures, stylistic alternates/sets, etc. 6. Whats included 7. Bravura 8. Bravura The first SMuFL font (OpenType/SVG/WOFF) Includes all SMuFL recommended glyphs, and hundreds of optional glyphs Released under the SIL Open Font License Free to use, bundle, embed, create derivative versions, etc. Only licensing restrictions are that the font cannot be sold on its own; derivative versions cannot use the same name; and derivative versions must be released under the same licensing terms 9. Current status Version 0.85; targeting 1.0 release in 1H 2014 After 1.0, existing code points/glyph names wont change Remaining milestones to 1.0 release Technical guidelines for SMuFL fonts for text- based applications Release of a version of Bravura for text-based applications 10. Current status Supported already in LilyPond by way of openLilyLib Support coming in MuseScore 2.0, Steinbergs in-development scoring app, other as-yet unannounced projects Bravura already shipping with commercial products, e.g. from Rising Software 11.
