Soprillo
The soprillo (also known as the piccolo or sopranissimo saxophone) is the smallest saxophone, developed as an extension to the saxophone family in the late 1990s by German instrument maker Benedikt Eppelsheim. It is  long including the mouthpiece, and pitched in B♭ one octave above the soprano saxophone. History

Adolphe Sax's 1846 patent for the saxophone specified a family of saxophones in several sizes and pitches, ranging from the giant subcontrabass in B♭ to the sopranino in E♭. In the late 1990s German instrument maker Benedikt Eppelsheim created a B♭ instrument pitched higher than the sopranino which he called ,  or soprillo. It is sometimes also called a sopranissimo. Construction

The soprillo is pitched in B♭ an octave above the soprano saxophone—it is half the length of a soprano, measuring  with the mouthpiece attached. Constructing such a small saxophone presents several challenges. The keywork only extends to a written E♭6 (sounding D♭7) rather than F or F♯ like most saxophones, and the upper octave key has to be placed on the mouthpiece. The very small mouthpiece requires a correspondingly small reed and a tightly focused embouchure, making the soprillo difficult to play, particularly in its upper register. There is very little demand for soprillos, reducing the economy of scale and making the soprillo more expensive than more common saxophones like the alto or tenor. The Eppelsheim soprillo is the only piccolo-sized saxophone manufactured. Performance and repertoire
There is very little music written explicitly for the soprillo, given its short history. British saxophonist Nigel Wood has written several pieces for it, and recorded Soprillogy, a CD of music performed on soprillo. Saxophonists Vinny Golia, Jay C. Easton and Berni Attilio also perform and record on soprillo. References
