But if you're secure in the accompaniment - and assuming the pro is secure in his/her playing - I don't think there's going to be much of a problem. The rehearsal is DEFINITELY NOT GOING TO GO RIGHT, but that's what rehearsals are for. Since you've been asked to do the job you must be up to it, and it won't take long for you and the pro to sort out whatever needs sorting.
Hope the gig goes well.
Spent a happy few hours putting the marimba part into Sibelius so I could play it back and practise with it. I often do this - I know it's not the same as doing it with the soloist but I get to know what I should be hearing from the soloist while I'm playing - feeling confident on that bit.
No, I didn't get asked to do it. I'm accompanying a couple of other people for the concert, the organiser somehow got the percussionist to agree to play, and then told him that I would play for him without asking me first!! So I just get told that the percussionist is going to ring me. Although I'm really cross that it's assumed I'll play for anybody the organiser chooses to get for the concert, I'm also really looking forward to playing with a professional for a change. I've done loads of accompanying so I don't think I'll let him down but I'm always on edge when the only rehearsal is immediately before the concert.
