glossary - add 'high bass clef'

[Wendl, Arnold]

>ugly, or enhancement request

I think the "high bass clef" is an important information and should be added to 
the music glossary.

At the "vienna symphonic library" pages (http://www.vsl.co.at/en) --> vienna 
academy -->
Brass --> Horns --> Horn in F --> Notation, Section "older notation" you'll 
find some description of it.

I remember a report, Mozart did switch frequently between treble and high bass 
clef in a confusing way
in a certain basset horn part for Anton Stadler.

For my enclosed suggestion I counted the pitch usage in two sheet music prints
(also the publication years are more than a century apart) to illustrate it.


Best regards,
