I'm a journalist and on a recent job I was talking with the photographer and told him I'd been playing bass for 32 years. He just started last year and wants lessons. I showed a friend last year some basic arpeggios and patterns to play along with chords and how to just play one note per chord if she wasn't sure what to do, expand to Root-Fifth and then Root- Third -Fifth kind of stuff and that worked. So now the photographer wants a lesson tonight, and I don't know what to show him. I play country and classic rock and roll and he's into Lenny Kravitz and AWB and I've never listened to those bands. Ever. What do you do with a first lesson? Assess the student to see what he knows before trying to show them anything?
