ok, i just got the best gift in the world, an acoustic guitar. i've wanted to learn for a long time, so i'm really happy. but i have a few problems. like i dont know how to put on the guitar strap, lol. this must seem like a very stupid question, but how do you put a guitar strap on a guitar? i have a yamaha, if that makes any difference. thanks in advance, and do you have any tips for a 15 year old trying to learn guitar? thanks and have a good day.
