For me, I was around 9 or 10 years old and my dad (who had been playing for a couple of years) signed my sister up for group lessons. Now we were not a wealthy family by any means, so my dad probably wheeled and dealed to get a little 3/4 size acoustic for my sister. No again, we were a modest family but my sister never subscribed to that and the guitar my dad got was not good enough for her, so I talked him into giving it to me. He began teaching me some chords and basic timing, he played mostly Mexican folk music so I definitely learned that Ranchera beat. So, I guess I need to thank my sister for turning up her nose at that little acoustic guitar as it was how I came to play.
