I’m sure I’m not alone here, the first song I learned was Twinkle, Twinkle Little Star(who you callin’ little?). That was even before I started the Suzuki method. I’d be curious to learn what song other started out with?
Twinkle was also my first identifiable song, though I first just practiced with open strings and parts of the scale. I first started back before digital tuners were common, so I used the Twinkle interval to help me tune the strings!
