Answer:
Yes and No. And it really depends whether you want to strum chords or be the next Hendrix. If you practice playing a few basic chords first, you could be playing your first song in a couple of hours, but it may take longer. I was a relatively fast learner, and began playing blues solos on the electric guitar about a year after I first began lessons on an acoustic at the age of 14. I also knew many people who'd started on guitar earlier than I had but been satisfied only with knowing how to play power chords and the odd solo or fill. What it really takes is dedication. Anyone can become good at guitar if they have music they love, friends they want to play with and heroes they want to emulate.
