and the Italian clarino are all derived from the medieval term claro which noted an early variety of trumpet. This is likely the origin of the Italian clarinetto, itself a diminutive of clarino, and consequently of the European equivalents reminiscent of clarinette in French or the German Klarinette. According to Johann Gottfried Walther, writing in 1732, the reason for the name is that "it sounded from faraway not unlike a trumpet". The English form clarinet is located as early as 1733, and the now archaic clarionet appears from 1784 until the early years of the twentieth century. The cylindrical bore is essentially responsible for the clarinet's exceptional timbre, which varies between its three main registers, referred to as the chalumeau, clarion, and altissimo. The tone pleasant can vary
vastly with the clarinetist, music, instrument, mouthpiece, and reed.
