Soprano saxophone

The soprano saxophone is a small, high-pitched member of the saxophone family of woodwind instruments invented in the 1840s by Belgian instrument maker Adolphe Sax. Built in B♭, an octave above the tenor saxophone (or rarely, slightly smaller in C), the soprano is the smallest of the four saxophones in common use (the others being the alto, tenor and baritone), although there are smaller rare instruments such as the soprillo and sopranino.
