Thanks for the links, Jeri.

SPB-Cooperator, Bošilecký zvony is a beautiful tune and I can understand what you are saying about playing a wind instrument and trying to play an emotionally charged tune. As an example, I would have trouble playing Whispering Hope on my flute because a musician played it at my Mum's funeral 18 years ago. (Note: I'm not a good flute player anyway.)

If I'm practising the tune on my harp at home alone, no problems, but as soon as we start playing it in our session group, I get halfway through and start tearing up.

I don't know if this helps, but when I was learning piano for a couple of years my piano teacher suggested learning the pieces by playing the last few bars, getting that worked out, then back up a few more bars and play that bit to the end, and keeping progressing backwards until you get to the beginning of the piece and have ironed out the technicalities. I'm guessing that then you could start working on the emotional nuances. It might sidetrack your subconscious long enough to work out the technical performance aspects.
