Keeping the guitar in place

While playing the guitar your fingers will be moving all over it, and the guitar should be in place for your fingers to map the neck right. If it makes a move from the position tha tyou expect it to, it would be playing a different song than what you want it to. Learners usually keep their guitars on their lap while sitting down, and once they have perfected it to a certain extent, they suspend the guitar with a leather guitar strap around their neck so that they can dance and sing at the same time while playing the guitar too like all rock bands do.
