A recent post here mad me think. Why not ask a mando player?
This is a copy of what I posted on the Sibelius site/
"I bought G7 so I could transcribe standard notation for classical mandolin. Any tips on how to get piano music onto the mandolin. The low note on a mando is open G so I have been trying to use that as the base, not bass, but then sometimes the notes on the highest e string get over the 12th fret. I can play the 14th but only for a short passage because the short scale length of the mandolin makes it sound tinny. I could drop that an octave, but are there some other ways, i.e. use 3rds or a fifth on harmony notes, that are above G if you know what I mean.
I have been working on the Aria from the Goldberg variations and would like to figure out a way to play the bass notes that would occur on the on the G sting somewhere else so I can strum it with the E string, again play a third or fifth instead of octave or is that cheesy?
The mandolin is tuned G D A E like a violin"
