This is doubtless the origin of the Italian clarinetto, itself a diminutive of clarino, and as a result of the European equivalents such as clarinette in French or the German Klarinette. According to Johann Gottfried Walther, writing in 1732, the explanation for the name is that "it sounded from faraway not unlike a trumpet". The English form clarinet is found as early as 1733, and the now archaic clarionet appears from 1784 until the early years of the 20th century. The cylindrical bore is basically guilty for the clarinet's distinctive timbre, which varies between its three main registers, known as the chalumeau, clarion, and altissimo. The tone exceptional can vary enormously with the clarinetist, music, device, mouthpiece, and reed. The differences in instruments and geographical isolation of clarinetists led to the advancement from the last part of the 18th century onwards of several different schools of gambling. The most popular were the German/Viennese traditions and French school. The latter was based on the clarinetists of the Conservatoire de Paris. The proliferation of recorded music has made examples of various styles of gambling accessible. The modern clarinetist has a diverse palette of "applicable" tone features to make a choice from. Clarinets have the biggest pitch range of common woodwinds.
