Using a guitar strap is a must if you plan to play standing up. While many instruments have pegs on either end for attaching a guitar strap, some models only have a peg at one end. In this case, you will need to tie your strap onto the other end. It's important to attach your guitar strap properly so that you don't accidentally send your instrument crashing to the floor!
Slip the leather laces on the upper end of the strap underneath your strings at the bottom of the headstock. Make sure you don't thread the laces underneath the strings on any part of the neck, as this will cause the strings to buzz and possibly not vibrate very much at all.
Tie the laces in a double knot on the backside of the guitar.
Drape the strap over the shoulder of your fretting hand.
Pull the strap back around to your front, underneath your picking hand.
Push the peg at the base of your guitar through the hole at the base of the strap.
Hold the guitar in both hands and tug on it a few times to make sure that your strap is secure.
Adjust the length of your strap either by placing the peg at the base of the guitar in a different hole at the end of the strap, or by sliding the adjustable clip located on your strap. Your strap should have at least one of these accommodations!
