Dear Mr. Bogatko,  when a book about mechanical _music_ has no audible
examples added, e.g., a CDROM, it lacks of an important branch of its
subject.

Did already somebody, politely, lead you to this point ?

Best regards,

Horst Mohr

 [ The publisher's claim that the CDROM is "the most complete work
 [ to date on this theme" seems grandiose, but we should ignore the
 [ exaggerations of advertising.  Certainly the Schott CDROM complements
 [ other tomes about mechanical music.  Maybe someone can make a CD of
 [ music to play while reading Bower's "Encyclopedia"!  ;)  -- Robbie
