I am curious and just want to know the highest trombone note you've heard or seen on sheet music. So far, the highest note I've heard is during Mood Indigo by Wycliffe Gordon, around 2:16.

I've hit and sustained a 2-octave-above-bassclef-Concert F. Never seen that in music tho

Wow. So that's a triple high F? I have hit double B b. But can regularly hit double high d Eb and F
