Most fonts containing musical symbols use a glyph layout that was first introduced in 1985 with Adobe’s Sonata font, which accommodates fewer than 200 basic symbols. SMuFL is a specification that provides a standard way of mapping the thousands of musical symbols required by conventional music notation into the Private Use Area in Unicode’s Basic Multilingual Plane for a single (format-independent) font. Welcome to the web site for the Standard Music Font Layout, or SMuFL, initiated by Steinberg and now developed by the W3C Music Notation Community Group.
