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.
