Gee thanks to glasgow, leenia and others who've replied. yes I do know what a ratchenitza is, and do play Bulgarian music. Glas, I play it on wooden flute mate ( no, not kaval).
To the people who've suggested i try the mp3 downloads, these all seem to be the Kornog version which i have already.
M Ted, if you can dig out the dots AND FWD THEM that'd be grand. I'll try to repay the favour with a nice recording. If you have luck let me know at scwells@tpg.com.au .
Glas I think I've got parts a,b,c, down. I get lost somewhere in parts d-g. Don't know which one exactly cos I can't find my bloody cassette right now !!
