Now this is really off-topic but might amuse some. If likely to disapprove, please delete now.
I was once taking a sectional rehearsal for the viola in the student orchestra at the Luxembourg conservatoire (where they use the French system) when I found myself "translating" the rehearsal marks and saying things such as "let's go from three bars before Ré" instead of "... before D". My own viola teacher in a similar situation managed to say "après soixante-neuf revenez en première position". Strangely enough, I was the only one who sniggered. BTW, the language spoken in Luxembourg is Lëtzebuergesch, not French, but the good Burgers often find themselves obliged to change into French if there is a single "quarante-quatorze" or "quarante-dix-sept" in the room. (those are the départements that the "cent-onze" come from). Csirz To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
