I play guitar, bass guitar, drums and the piano.
Piano I started when I was five and stopped when I was twelve, so I'm not as good as I was but I can still learn music and play it well enough providing it's not incredibly hard.
I started teaching myself guitar when I was twelve, and about a month ago I started getting lessons, mainly because over the past six years I've been happy with my skill level (like when I'm in a band I can play what needs to be played) but now I want to start playing jazz guitar at wineries to make some extra money and I don't consider myself that good to do it yet.
Bass guitar was pretty easy to pick up after playing the guitar, because it's pretty much just the top four strings of the guitar except thicker. Again, self taught, but I don't know how to do slap bass or anything, mainly because I think the style's a bit obnoxious (I actually prefer playing bass in bands to guitar because it's in the background and subtle). To give an idea of where I'm at, the most complex thing I've played is Hysteria by Muse, so I'm definitely not amazing at bass but I can play the sort of bass lines that are in most genres.
Drum kit I started just before I turned thirteen after inheriting an old drum kit that used to belong to my uncle. I'm self taught and out of all the instruments I'm probably most confident on drums, although again there are many better players. I usually play unaware of how I'm playing if that makes sense - like a skilled drummer would know exactly which hand would be hitting which drum whenever they do a beat or a fill, whereas I just play whatever sounds good.
