Clarinets are transposing instruments, and are made in several keys, some of which are quite rare. The most common key is B♭. The B♭ clarinet is about 60cm long and has a range of three octaves. A clarinet in the key of A, slightly longer than the B♭ clarinet and pitched a half-step lower, is often used in orchestral playing. Clarinets are also made in the key of B♭, pitched a fourth higher than the common B♭ clarinet, and even in D, although this instrument has become uncommon. | Clarinets are transposing instruments, and are made in several keys, some of which are quite rare.
