Thanks Stephen. I keep meaning to post a new improved version of this video, or something better along the same lines. Watching it back there's just a few things that jump out at me I should have done differently.
Including, but not limited to:
1. The second time round with "dynamics" doesn't actually sound that different from the first time. I used too much compression on the sound recording so it all got squeezed out to a similar volume.
2. Would have been better to do right hand note lengths before dynamics.
3. When I bring in the left hand it's already pretty much the long bass and short chord that I do habitually. Should have made it all short or all long first time to show more of a difference the next time round with "left hand note lengths".
Plus the whole thing could just have been a bit tidier and more planned out. But anyway, I hope you find it useful as it is for now.
