Four.

Ok, this may have been a bit much for me, seeing as how out of practice I feel, but what the heck. French horn trio. I was trying to do a short fanfare, then got tired very quickly and the whole thing just seemed to slow down a bit.

For those of you who try playing this on some instrument and notice the pitches don't match up, remember that the French horn is a transposing instrument. This is written for a horn in F: in a sense, a written "C" is a sounding "F." (One of these days I'll explain some reasons for transposing instruments ... just not today.)
