noun
flute
FLOOT/fluːt/
A woodwind instrument played by blowing across an opening.
The musician plays the silver flute horizontally across his face.

Etymology
Fleute already named a musical pipe, so the instrument meaning is inherited. The name predates the modern transverse flute and also covered older instruments blown straight through a mouthpiece.
In context
that's really a challenge for a singer, for a flute player, because we lose so much air. We have no resistance with a small breath. We need to play for 20 seconds.
