The next time I play with any Greek balalaika player who is over 1000 years old and we are playing dorian tunes I'll make sure we agree on whose mode we choose otherwise it might sound horrible.

In the meantime I think I'll stick to the chord set I'd go with from the modern definition that most of the people I play with would understand and expect me to play :) Thanks for the tip though it could be invaluable.

Perhaps we might be in danger of slightly over-complicating this thread rather than getting back to slightly more basic questions like 'What tune is that called?'
