It's decidedly non-standard. I'd call it a curiosity or an oddity, but someone might punch me in the nose.Originally Posted by gravehill
I'd not use them in lieu of french horns, but certainly as an ADDITION...Stravinsky does that in Rite of Spring. Here's a foto. Note that the instrument is played left-handed. By a horn player (not shown). Using a horn mouthpiece (present, but if you can see it I worry about you)
It is less mellow and more "present" than a regular horn. Note also that the horn points its bell to the back of the stage, whereas this thing points to the side. It's also a bit wider-bored than a horn, which also helps to impart the extra presence.
I don't have the score in front of me, but Rite of Spring uses at the max 4 or 6 horns and at least a couple Wagner Tubas.
The consensus use of the thing seems to be as horns 5-6-7-8 or as a bridge between the horns and the tuba.
As little as this instrument is used, notating it causes more problems than allother instruments combined.

EGAD...the thing has its own website
