Used by

Attribute ClassesThese class-based attributes use data.CLEFSHAPE

att.cleffing.log/@clef.shapeEncodes a value for the clef symbol.

att.clefShape/@shapeDescribes a clef’s shape.

Allowed Values

GG clef (Unicode 1D11E).

GGDouble G clef. Sounds one octave lower than G clef. (See remarks on usage below.)

FF clef (Unicode 1D122).

CC clef (Unicode 1D121).

percDrum clef (Unicode 1D125 or Unicode 1D126).

TABTablature "clef"; i.e., usually "TAB" rendered vertically.

Remarks

Double-G clefs sound one octave lower, so do not combine with @dis/ @dis.place/@clef.dis/@clef.dis.place. In some cases the double G clef may be used to indicate that two voices share one staff and does not sound one octave lower. In this case the @oct attribute may be used to clarify the sounding octave of the instruments for the clef.
