Hi Amergin. I've always found Grey Larsen's approach to ornamentation very helpful. It's a more analytical approach than many. It really made sense to me and allowed me to get my mind around what was happening with ornamentation. He has several different books where he outlines this approach (https://greylarsen.com/webstore/books).Amergin wrote: Does anyone have any tips for how to get good at ornamentation or any resources/tutorials that you particularly recommend?
The key point for me (others have mentioned it in this thread) was that ornamentation's main role is to articulate consecutive notes of the same pitch. I assume this developed at least in part on the uilleann pipes where there's not an easy way to articulate consecutive notes of the same pitch. On the whistle you could just tongue each note to get the job done, but this doesn't sound very Irish, but I do think judicious use of tonguing sounds quite good.
