Finding a motion mechanic that is fast and relaxed is the most important thing. However, coupling that mechanic with the left hand, with a system/strategy for synchronization is the resolution of the latter!
I know that Troy has touched upon “chunking” here and there and on the forum at times, but this topic needs a section in the Primer ASAP. Honestly, I’ve always been a bit put off why this step has largely been ignored by CTC overall?
Real-world examples of getting your motion mechanic and your left-hand working together, and how slow practice works with that. Speed bursts, sequences, fragments, metronome. How does it all tie in?
I want to see the actual process of getting both hands working together over musical examples. Start with speed… great. Show me how you did it!
