The Bravura and BravuraText Music fonts provide thousands of music
symbols. BravuraText glyphs are specifically \clefGi\ designed
\clefFi\ to be used \clefCi\ inline:

clefs:~ \clefG\ \clefC\ \clefF\ ~time signatures:~
\timeC\ \timeCHalf\ ~accidentals:~ \sharp\ \flat\ \natural\
~notes:~ \wholeNote\  \halfNote\ \halfNoteDown\ \quarterNote\
~and much, much more.
