George Lowen Coxhill known professionally as Lol Coxhill, was an English free improvising saxophonist. He played soprano and sopranino saxophone.

The sopranino saxophone is the second-smallest member of the saxophone family. It is tuned in the key of E♭, and sounds an octave higher than the alto saxophone. A sopranino in F was also described in Adolphe Sax's patent, an octave above an F alto (mezzo-soprano), but there are no known built instruments.
