It all depends on if you want sex or a relationship.
I'd imagine the sex thing is easy. Especially since women are most of the time the attention-seeking whores movies/games/books/talk-shows/life/parents/friends make them out to be, so just shining a torch in their direction and talking to them like a normal person, and not like a scared virgin bastard, would most of the time get you some.
I also play a bunch of instruments and compose music, which half of the time would be 60's psychedelic pop, while the other half is jazzy dance music and females seem to fall in love by the mere mention of that fact.
Finding a long-standing relationship has been a bit harder for me though, since I've only met one girl in my life that I really loved and really admired her personality, but after a few months of hanging on for dear life (on both ends) we fell apart. Now I'm having trouble finding a girl that isn't only interested in sex and bragging about how her boyfriend plays piano/guitar or the double bass for the hipster girls and also never taking the time to think, instead of absorb bullshit from the world.
But to the heart of the question - I tend to grow and harvest my relationships, unlike the regular approach of "Enjoy it to the max for the first month, then just drift apart". I try to build up a connection, before I decide to propose a relationship. It's like testing the soil for your garden space.
That being said - I just try and start a friendship by going up and just talking to the girl, or maybe having some mutual friends get us to meet. It's a lot easier for twats (Like I used to be) when you take out the "Uhh... Umm... I just wanted... To ask if... You know, you will... Yeah... Go out with me.. I guess... If you'd like, that is..." part.
But as a general tip - just fucking go for it. The ones you like are as human as you are and want as much attention as you do, or more. Just be a bit more confident and don't be a jackass or a sweety-pie. Be kind, but think for yourself too. It is balance, that keeps the things flowing.
Sorry if I took too long, I always seem to get a bit sidetracked or explain in too much detail.
