Need clarification, brass instruments, pre-1900 score
I'm transcribing scores from the late 1800's. The score in question is in e-minor.
I believe the two 'corni' are NOT cornets, but french horns - is this correct? I don't understand why said FH's (which are assigned "in E" and "in C") do not show what I would have expected for key signature. Why are both shown key signature 'C'?
Also, I'm assuming 'trombe' means 'trombone'. I'm unfamiliar with trombone "in anything", but here the score wants "trombe in E". Does that jibe with the key signature of 'C' - for it? Thanks.
