Slap Tongue

What it is: Pressing the tongue firmly against the reed, building up suction, and snapping it back to release a percussive "pop." Found exclusively on single-reed instruments — saxophones (where it's a staple) and clarinets (less common but possible).

What it sounds like: A dry, woody, percussive pop — almost like a slap bass on an upright — sometimes with a faint pitch, sometimes pure attack. Bigger horns (bari sax, bass clarinet) slap harder and louder.

When to use it: Funk/jazz/Latin saxophone writing, rhythmic comping, percussive accents inside a melodic line, modernist effects. Bari sax slap-tongue is a famous sound in Latin jazz.

Notation: "+" above the note, or a footnote "slap" or "slap tongue." Some scores use an X notehead.

Tip: Slap tongue takes a strong jaw and embouchure — student players may not have it yet. It's easiest in the lower register and on the bigger horns. Don't write a fast melodic line as slap tongue; use it for individual accent notes or repeated rhythms.
