About this fingering
This is the standard fingering for written B♭4 on alto, soprano and tenor saxophone. All three use the same keys, but they sound at different pitches: alto (E♭ instrument) sounds D♭4, soprano (B♭ instrument) sounds A♭4, tenor (B♭ instrument) sounds A♭3. In the diagram a filled circle is a key you press and an open circle is one you leave up. The small shapes around the main holes are the octave, palm, pinky, side and bis keys.
Fingerings can differ slightly between saxophone models, and altissimo notes vary most. If something looks wrong, tell us and we will check it.
