Hi, FM.
Hanneke uses these ornamentations fairly frequently, with “The Scrunch” being the least used technique. I would start with The Cut, The Hammer On and The Flick as these are simpler and other techniques point back to these.
The Waterfall is more difficult and is based on the Flick, so learn the Flick before tackling the Waterfall. Same with The Roll and The Wiggle…these are more advanced, so learn them after the others.
I would recommend reviewing all of these technique videos and then referring back to them as you work through a tune Hanneke teaches…
I’ll think about numbering these…might be a good idea to reformat them into some suggested order of learning.
Hope that helps!
