Do you know the magic L ?
Do you know why some chords sound better together than others ?
I didn't & I've been playing for over 20 years.
my naivity was to skip GF 1&2 , so glad I decided to start at the beginning.
I've picked up things from Lisa that every guitarist should know imo.
The lessons are easy to follow & if you know your chords etc already than great, watch the video & play with the band & move on.
