I've played the guitar since... not exactly since I was born, but as near as was physically possible.

I didn't start to take it seriously until I was 15, though. My dad taught me, but I never had formal lessons. I started off learning the steel-strung acoustic, and got an electric guitar when I was 16. I play blues, ragtime, folk, rock, metal, and my own random unclassifiable invented noise.
I played the flute for 8 years and got as far as passing Grade 8 (the highest of the numbered RSM grades). As part of this, I also took Music Theory up to Grade 5 (this was compulsory before you could pass to Grade 6 of the practical exams). So although I never had formal guitar lessons, the music theory was helpful for that, as well.

I used to enter competitions as solo, duet, trio and part of an ensemble, which was really fun. On the flute I played classical, jazz and some... how do you call them? songs from the shows, and light stuff.
When I was 19 I started singing lessons which I carried on for 2 years but didn't take any grades. I've always enjoyed singing and I still love it. The lessons were really fun, and the techniques are of course still useful to me now.

My singing teacher was 'operatic', and also for fun I used to sing the alto part in a 4-part choir, which sung religious music and light songs from shows and old-fashioned popular music.
I haven't played the flute for a long time, but continue to play the guitar (electric and acoustic) and sing. I'm also teaching myself to play the keyboards (can't afford a piano, sadly). Music theory is helpful with that, too, as it means I can read the bass clef without too much effort.
I've dabbled in the recorder (descant and treble) and the Irish tin whistle, but I wouldn't exactly say I could 'play' them!
