Thanks very much for taking the time to look through the score and for the ranges chart – I’ve saved that for future reference!
Thanks for your point about the key signatures. I’ll take the third piece down a semitone so it’s in A Minor rather than G# minor! And I hadn’t realised that one of the pieces was out of the range of even a tenor melodica, so I’ll sort that too.
Yes, the bass melodica is one of my main concerns, particularly with difficulties around control and attack around the lower range. I’ll see whether any of the notes need to be raised an octave for ease.
