I'm an amateur guitar player in Brazil and I wrote a song for my girlfriend for our 2 year anniversary, which is coming in May. It's a simple love song, which runs for 2:47 minutes at 110 beats per minute. I'm recording it with GarageBand for iPhone (I wasn't kidding when I said I was an amateur) and I'd love to add drums and bass to it. You should feel free to record whatever you thinks sounds nice with it. I'll add the Portuguese lyrics later, and if you wish to help, I'll be glad to send you the final version once it's done.
