This is a shorty that I did and like - that has bosie sounds.
LINK1 - shorty
The rounded/mute bosie sound is quite nice. Need to listen through nice speakers or headphones etc though. Not through mobile/cell phone speakers.
And then can do some really basic semi-impro, and the usual - and then I listen to the semi-imp to see where I need to change things up a bit, in order to refine or whichever directions we want.
LINK2 - longer
The ending in the longer semi-imp is a bit weak hehe ... and so are various bits of it. But that's usual for some semi-imps. And of course, when there are so many tunes we like or love out there - the piano keeps us forever super busy in a very nice way, having unlimited fun/enjoyment.
