I'm starting to study orchestral excerpts with my private teacher and a couple of them are in C (Pictures, Pines of Rome). My teacher has me playing them at sight, which I think is good for me.
As luck would have it, I'm playing at a friend's church for their Christmas Eve service (traditional carols and other fun stuff) and I'm playing the soprano line out of the hymnbook (I think) which is - you guessed it - in C.
These carols aren't that hard; standard G and A major type things, but there's one in E and one in F# which I'll probably write out as a safety net. However, I want some advice - should I try to read them at sight or should I write them out for the added security?
