There is no known “Suprno” saxophone. This is most likely a misspelling of soprano saxophone, a high-pitched, B♭ woodwind instrument in the saxophone family. 

The soprano saxophone is often seen in two main forms:

• Straight: Resembles a clarinet.
• Curved: A less common miniature version of the familiar alto or tenor saxophones. 

Features of the soprano saxophone

• Pitch: Pitched in B♭, sounding an octave higher than the tenor saxophone.
• Intonation: Playing the soprano saxophone requires more skill with breath control and embouchure to produce a consistent tone and play in tune, especially compared to the larger alto or tenor models.
• Sound: Can produce a sweet, bright, or piercing tone, depending on the mouthpiece and playing style.
• Usage: While less common in large ensembles like concert bands, the soprano is a well-known solo instrument in jazz (famously played by John Coltrane and Kenny G) and is also used in some classical compositions.
