hey guys, after a guitar lesson today my teacer is teaching me castles made of sand by jimi hendrix, and when i come to the part with strumming like F, Am, G, etc chord, he was telling to do pinky slurs while strumming them. I know he means for me to hammer with my pinky during the strum, but i dont know which notes to hammer on. I know this is sort of a specific question but if anyone can help, that would be great. Thanks in advance.
