Here's a quick whistle (caution: I'm often sharp)

Anyone know the name of it?

Oops, forgot to add email notifications...

So, I'll add that I think it's a French Horn Concerto.

Based on the rhythmic pattern, I'm going to make this a little less vague and say that it's probably one of Mozart's four horn concerti. For some reason, Haydn comes to mind, but I'm not sure if he even wrote a horn concerto. Could you tell us something more about the rest of it, or maybe something of the ensemble?

Just checked these out:

It sounds a lot like the 3rd movement of Mozart's 4th horn concerto, but not quite that.

I heard it on the plane... United's XM satellite radio. I don't have any more info on it :-\

Ahh, you were right! It's Movement 3 of Haydn's trumpet concerto:

Sounded a lot on the French Horn, though.

Thanks

Good work on tracking it down! I'll have to look into this piece more.
