I’ve been developing my ability to improvise counterpoint on guitar for around 20 years. It wasn’t until I took a counterpoint class in my undergrad that I started to have the breakthroughs to really be able to play convincing baroque sounding 18th century style counterpoint fluently, and this style is the base that’s I use to improvise or compose in any style. The Score/TAB to the Study I wrote to help you get started learning to understand counterpoint on guitar and start to develop your ear is free on my scores page when you sign up for my email.
If you have any issues message me on your preferred social/email to have me send you a copy. Thank you, and enjoy!
