Bagpipe \Bag"pipe\, n.
A musical wind instrument, now used chiefly in the Highlands
of Scotland.
[1913 Webster]
Note: It consists of a leather bag, which receives the air by
a tube that is stopped by a valve; and three sounding
pipes, into which the air is pressed by the performer.
Two of these pipes produce fixed tones, namely, the
bass, or key tone, and its fifth, and form together
what is called the drone; the third, or chanter, gives
the melody.
[1913 Webster]
