I wanted to talk about an aspect of guitar playing that may be a big deal to some, not so much to others. And that is playing guitar standing up. I think for electric guitar players its less of an issue, but i know alot of us acoustic players tend to play sitting down. However, if you ever plan to perform i would say spend some of your practice time playing standing up. There are a few things that are a bit different and will take some getting used to.
 
For starters you cant really hunch over the guitar and look at your fretting fingers as you are playing. I think this is probably better for ones posture, but it also forces you play more by feel than by sight. You can kind of look down at the top of the neck and reference your finger position from the fret markers on the side. So that takes some getting used to, and playing your usual tunes will be different at first, especially if they involve any hot solos.
 
I find it easiest to play standing up if my guitar is up high, pretty much where it would against my chest if i was playing sitting down. This may look a bit odd compared to alot of rockers who bang out songs with their guitar slung low, but its what works for me. Experiment and see what works for you.
 
Personally i like it when performers stand up to play. I feel it lends more energy to a show. Coming mostly for an acoustic/traditional music background, alot of performers will sit down to play. This can work ok, especially if the stage is elevated enough. But for high energy music i enjoy it more if the performers are standing. But thats just me.

If you play acoustic guitar there are two main ways to attach a strap so you can play standing up. First off you will need a strap button installed on the butt of the guitar. Its recommended to a competent repair person do this, drilling the hole wrong can split the heel block on the inside of the guitar.
 

 
Next you will need affix the strap to the other of the guitar. Some musicians will do this by just tying the other end of the strap to the peghead. I feel this works ok, but i prefer to have a stap button installed on the heel of the neck.
 

 
This lets me have more control over the angle of my guitar in relation to my body. If you get a strap button installed be sure to get it on the treble side of the neck or the bottom of the heel. Again, have a qualified repair person do it, drilling out the hole wrong can split the heel of the neck, which is no good.
 
I think playing standing up is something worth experimenting with, even if you only do it some of the time. Plus its easier to jump off stage and start crowd surfing if you are standing.
