Enharmonic accuracy or ... ?
I'm writing a quartet for classical guitar in C#m containing arpeggiations of these held chords: C#m, E/B, G#m/B, D#/A#.
The final chord currently contains Fx. This makes harmonic sense as it keeps the intervals correct, and therefore identifies the chord correctly, but I feel like I'm being fussy writing the arpeggio as A# Fx D# A# rather than A# G D# A#.
This is especially because I don't need to distinguish between different types of F or G in the chord (ie the music is firmly diatonic so I'm not using the double sharp to limit unnecessary accidentals) and so having the double sharp in there feels like I'm being technically correct but a bit fastidious.
What should I do?
Do I stick with harmonic accuracy or give the musician the more familiar spelling even though that obscures the harmonic intention (and makes me look harmonically illiterate!)?
I would never write a D major chord as D Gb A so why am I getting worked up about D# major as D# Fx A#?
Any advice greatly received!
