Fliss.Iwould suggest listening to sliabh luchra music[Imsure you do already]and purchasing the following books Munster bowing styles for the fiddle by David Lyth[ he has also produced a SLIGO style fiddle book ,ColemanKilloran Morrison].Matt Crannitch fiddle book,these give an idea on where to ornament,I adapt the ornamentation TO SUIT The English Concertina,and if I dont like something I leave it out etc.,but most of it I find I like,I also nick ideas from pipers.
