The chanter is straight bore, and usesa practice chanter reed. The tenor drones sound the same note as the chanterlow A. From the collection of Richard Mao. The newest addition to the list is pictured at right. They are a half-set of Uillean pipes, courtesy of BagpipesGalore , The Royal Mile, Edinburgh. The half-set differs from a fullset in that it does not have any keys.
Uillean pipes are native to Ireland,and are bellows blown.
A full set of uillean pipes has a two-octave range,and three drones, tenor, baritone, and bass. The drones are tuned an octaveapart, with the tenor tuned to the lowest note on the chanter. The Scottish manufacturer has thankfullygone out of business. They change octaves over a four-octave range, can switch between bagpipescale or chromatic scale, and can be played with headphones for practice. The chanter has electrical contactsin place of the holes.
