Here's a video of me demonstrating something I'm working on at the moment.
It follows on from this notion of "speed" I've been investigating for the last little while. My last post on this subject discussed polyrhythms expressed as ratios. This time, it's about moving between divisions of the beat to give a sense of speeding up/slowing down.
Initially I was planning on notating a bunch of figures and showing how they could put into different divisions, but I've recently been practising Ligeti's etude, 'Fem,' and using it as a vehicle to practice in beat divisions from 3 through to 9.
The excerpt I play in the above video is bars 25 to 30.
A similar thing happens in Scott Tinkler's 'Going Down'
Those are quaver triplets at the start, to give a sense of where the crotchet is......
