I don’t normally post Dan’s weekly lessons, but this one is worth sharing IMO. I suggest signing up for his newsletter and sub’ing his YT channel, but here’s the direct link to his webpage where you can download the notation and tab for this etude that he wrote last night. He’s a gifted British bassist. His wife is French from a town 90 minutes south of me. He recently moved from Singapore to Malaysia, following his wife’s career. It’s a small world.
