Which word is both a drinking glass and a musical instrument?

The champagne flute is tall & slim in order to maximise the depth of a given volume of fluid. This keeps the pressure as high as possible during the drinking process. The idea is to prevent the drink from going flat.

I would like a flute of diminished 7th's and champagne please!

Lunatic, But what musical instrument is a stein?

Lunatic, Beer steins are very popular in Germany

Lunatic, I think a stein is a mug, not a glass.

A stein is a drinking glass also. Has no one else heard of a beer stein???? I take umbrage with this one.

Snance, yummy!
