I'll go first. These. When I charted them for the first time I felt like a genius and I called them half-jump-trills. Then I tried to play it and some of the variations were VERY hard to play but I liked em. Basically they're just a trill but with a chord on the 1/1 beats, or for what song I was charting at the time where the accents of the song were, like the drum hits and all that. Ok, your turn.
Dense hand streams are pretty fun but are a bit hard to read. But once you get good at reading, they're fun to play and pull off.
Fast Hand Streams make my brain melt.
tbh i really like chordjacks but they get exhausting to hit after a little bit but, still they're really fun this chart has some of the best use of it for me, i can start off really good with it but then i start to fall off hard lol i've done chord jacks in my charts too, which was really fun to do because i was able to chart it so that my hands dont get hella exhausted
