In classical music, a gracenote takes time away from the note that follows it -- the only way that can happen is if it starts on the beat. As you say, it creates and resolves a dissonance.killthemessenger wrote:Akiba wrote:Remember they aren't grace notes, i.e. the cut occurs on the beat not before the beat like a grace note.
I may well be mistaken, but my understanding is that grace notes (whether acciaccaturas or appoggiaturas, and also more complex forms) are usually played on the beat, not before it, because they introduce and resolve a dissonance in the melody.
I've spent a bit of time trying to understand the details of the timing of embellishments in Scottish pipe music, and it's not easy to say exactly what happens. I suspect some of the same thing happens in ITM. If you really analyze what's going on you'll probably find that the exact placement of different embellishments varies by the performer, and also by the tune. Sometimes a bit of a delay for musical effect. Sometimes a substantial change from what "theory" would predict.
We all understand that intuitively though -- it's the difference between what generic music notation software produces when it plays back a score and what a musician produces.
Not that it matters, but if you google [ tin whistle ornament strike ] you find that a lot of people use the term, including Grey Larsen.
