A thread from one of the other gypsy guitar lists was on 'Tremelo' technique and it was great. A few contributors laid out their practice and development techniques and the combination provided a better treatise on the topic than has ever been covered in any books I've seen.
How about Octaves??
Robin Nolan had a Octaves page in one of his books but I'm looking for more help and more practice methods in developing clarity, smooth changes and good tone.
Any thoughts out there??
