Voted yes. Played saxophone for 3 years in middle-school, and thats the only formal music education I've ever had. Since then, I've picked up (in order): guitar, a little bass, piano. I'm still best at saxophone but don't play it nearly enough. I've been having a lot of fun lately playing piano and teaching myself some basic music theory: dunno why but its just easier for me to grasp the concepts learning them on the piano.
