Thanks to all of you for listening!
This is the rather rough-sounding audio mock-up of the earlier version (I can't find the original score at the moment, but the changes were mostly a lot of small alterations to the orchestration, dynamics, articulations, etc.): http://hep.bu.edu/~slinden/Music/Symphony_in_C.mp3
That's right - personally, I don't see the point of adhering to artificial restrictions like using natural horns, even when writing in this style. The important thing, for me, is writing parts with the [i]character[/i] of natural horn parts, even if those parts aren't technically playable on a natural horn.
I do also take your point about the first movement being a bit too bombastic, but it is meant to be a C major "trumpet and drums" style symphony.
I thought that trumpets in C were still standard in the orchestra, while B flat trumpets predominate in wind ensembles, jazz bands, etc.?
And yeah, I'm in the habit of writing timpani rolls as trills from reading scores of classical works, though I know that's not the standard anymore, and I should probably re-train myself.
Again, thanks to everyone for your feedback!
Edit: Do these boards not use BBCode anymore? They're not parsing my [QUOTE="Name"] syntax. Oh well, I guess I can fix it.
