Abstract: The present invention is a hand-held musical pipe wind instrument in which sound is produced by the vibration of a single reed and which replicates the relative scales and tone-hole arrangement employed on the Scottish Highland bagpipe chanter. In its most basic embodiment, this wind instrument consists of a saxophone reed and mouthpiece attached to the upper end of a tube and a flaring bell or sole attached to the lower end of the same tube. In this basic embodiment, the tube comprises a plurality of holes, known as tone-holes, disposed at locations along the length of the tube, which in playing are opened and closed successively in predetermined configurations to achieve changes in musical pitch.
