The Great Highland Bagpipe (GHB) is native to Scotland and is the pipe
most people think of when bagpipes are mentioned. Main pipe components include
a bag, a blowstick, a number of single-reed drone pipes (usually three), and a
double-reed chanter. The GHB is usually played in a standing position with the
bag held between the piper's arm and side. The drones rest against the piper's
shoulder and point upward. The bag provides a constant supply of air to the
pipes, and is inflated by blowing into it through the blowstick. The piper
produces sound by inflating the bag and applying pressure to the bag with the
arm. The air escapes through the drones and chanter, via reeds placed within
each pipe. The drones produce a constant tone in accompaniment to the chanter.
The GHB usually has three drones: two tenor drones tuned an octave below the
chanter's low A, and a longer bass drone tuned one octave below the tenor
drones. The chanter usually has eight finger holes, two tone holes, and a
range of nine notes from low G to high A.
