A conically shaped, keyless plastic wind instrument with eight holes, consisting of a single body and a detachable a mouthpiece. The instrument is fully chromatic and capable of playing in any of the traditional twelve keys of Western music-producing notes through a player's vibration of a single reed affixed to a soprano saxophone type mouthpiece, and through the opening or closing of a plurality of tone holes along its length by use of the fingers. The instrument is one of a family of keyless saxophones which can be pitched in the alto, soprano, and soprano range by the lengthening or shortening of the body and by changing the location of the eight finger holes. By opening or closing the finger holes, the standing sound wave-created inside the instrument by the player's vibration of the reed affixed to the mouthpiece-is intersected at locations along the length of the body producing a vibration at a determined musical pitch, the scale of which is tuned to A=440, standard concert tuning. All members of this instrument family have the same fingering patterns, which are based on recorder (or vertical flute) fingerings.
