classical guitar is one of my passions. When I'm too lazy to transcribe the sheet music into playing positions, I'll search www.classtabs.org and use the tab as a guide. (mostly Tarrega's music)

The rasgueado technique is something you'll have to learn for flaminco and modern classical guitar, and for most it takes a longer time to sound competent versus learning to play standard pick strum guitar.
