How do you pronounce Erik Satie's "Gymnopedies"?
I have a student playing the first one in a recital and she has to announce it.

Satie was French so the original pronunciation
was most likely French: zheem-no-ped-ee
(with no real stress on any syllable).
Another possibility, less likely, is a
Latin type pronunciation: gim-no-PED-ee-ess.

But in English-speaking countries words
like this are usually adapted to an
English-style pronunciation, which, based
strictly on the spelling, should
be: JIM-no-ped-eez. But this sounds rather odd,
so maybe a more conservative
English-style pronunciation might be
simply: JIM-no-peeds (rhymes with
centipedes, a word everyone
would be familiar with).

I was looking on some forums on the web and
someone said the way to pronounce it
is: GIM-no-ped-eez, a combination
of the English and Latin
pronunciations.

And what does it mean...?

I have been trying that piece, how long has your student been studying ?

The "gymno" part is definitely Greek = "naked".
