+Beginning in 18th century the high bass clef used in French Horn parts
+for the lowest pitches.  This usage of the F clef was then passed down
+from the French Horn to the Basset Horn and then to the Bass Clarinet.
+It looks identical to the standard bass clef, but is pitched an octave
+higher -- octavation indicators on clefs appeared at the beginning of
+the 20th Century.
+
+In LilyPond, the most straightforward way to make a high bass clef is to
+print the modern version @code{\clef "baas^8"} but without the @code{8};
