I've been arranging The Nutcracker Suite for Piano Duet over the past several days and I've reached a dilemma in my arrangement. To 8va or not to 8va for Dance of the Sugar Plum Fairy? I mean, with 8va, it does sound more like the celesta since it is an octave transposing instrument(the Celesta is), but it makes the already existing dynamic difference even more pronounced(which I made it piano dynamic in Piano Primo instead of the notated mf because I know the Celesta is quiet) and it's way up high towards the limit of the piano's range. Plus, I'm not sure I'll be able to get every note the Celesta plays in this movement if I use the 8va. And it's cumbersome to have to notate 8va in 2 staves for over 12 bars.
I know I use the very low bass in this piece, like E1, but that's because I have to when the cellos and double basses are in octaves as they are a lot of the time(plus, octaves sound good and give that more orchestral sound to the piano). With this 8va, I don't have to do it, it's a question of whether I should or not. I'm leaning towards the no 8va option, but I want some input from others before I go any further with this. The PDF shows the no 8va option. The movement I'm asking about starts at Page 28 of the PDF.
