I'm not a horn player, I'm speaking as an orchestrator. I'm just wondering, how fast can a horn play a chromatic scale? Descending and ascending. For example, this passage (for 4 horns) is to be played at about 150 bpm (the beat being a quarter note). How difficult is this passage to play? (The small slur indicates the first note should be scooped).
I'm just trying to gain a better understanding of the instrument and what is possible in terms of faster playing. Thanks.
