Here's my work in progress on the drum kit. Completely doing my head in. That's snare and kick on the 8th notes; easy, that's a beginner exercise, rudimental paradiddle.
Add cymbal tap every 3rd 8th note; impossible. I can only do it by reading at the moment, just mindlessly cranking. Might be 100 minutes+ by now? Fortunately for the neighbours I'm on the electronic kit.
