traverso
A transverse flute of the Baroque period, made in three or four sections with a conical bore from the head joint down.
The historical range will be confined basically to the 17th and 18th centuries, Mr. Polisi added, because the Baroque and Classical repertory allows students to transfer their skills between instruments, with, say, conventional string players adapting to gut strings and Baroque bows, and modern flutists to wooden traversos.
Where it comes from
Borrowed from Italian traverso (or flauto traverso). Doublet of transverse.
