I took up guitar pretty late in life, about age 38 or so. I'd strummed a few chords back in college but never took it seriously. I got an electric guitar and an amp in my late 30s and decided I wanted to see where I could go with it. There's something to be said for getting a little older - you find more focus and purpose for an interest.
What helped me a lot when I started out:
- Playing rhythm guitar against a backing track and/ or drum track. That helped me develop good time as well as endurance (it's a five-minute song? Well, you're going to play on time for five full minutes, no matter how tired or sore your hands get.)
- Playing rhythm also helps you see the chord progression and the structure of the song - here's the verse, here's the bridge, here's the chorus. Very helpful for when you start writing your own songs. You also learn to appreciate the talent of the stars who went beyond 3-chord folk or blues. ("Little Wing" is one of the most peculiar songs ever written.)
- Playing with other people who are better than you, in a semi-structured jam session. You get to hear how you sound playing with others, bass and live drums.
- Playing in a band. Showtime! Got those chord progressions memorized? We'll find out, won't we? I was asked to join a classic-rock covers band with guys who had been playing for decades. Shaped up my playing, and got me over the initial bouts of stage fright. (When I led off the opening lick of "Sunshine of Your Love," that great vibrato was my hands shaking.)
- Recording yourself. The tape doesn't lie. It shows you when your bends are flat, your rhythm time is shaky, and your solos are boring. Being honest about listening to yourself will make you get better fast.
