Your replys are great! I just did a workshop with Ken Perlman and I am very excited about playing the material he gave me. It just occured to ask your opinions, and I'm glad I did.
In the material I'm learning there is a lot of melody. Fretting the 7th fret is not uncommon, and off string pull-offs help you pull it off! (Pun intended) It does take some getting used to, but the tunes are great. I'm learning "Sean Ryan's Polka", "The Duke of Perth" "Lass O Gowrie", Mrs.McCleod's reel", and "Brae Reel".
The tunings used are open G, C tuning, and mixolydian (G,D,G,C,D). I love that last one - very modal.
Uncle Jaque, vous etes tres amusant! (Sorry, don't know how to punctuate with accents and circumflex)
