I'll pick up my guitar as a habit when i walk into a room. It feels comforting to have it. I do usualy have a urge or desire to play it, but i'de be unable to express myself on it unless i made myself practise to make sure i dont suck to much =P peace.
in specific...when I'm inspired by things that are so beautiful I don't know what else to do but make music...or similarily when I feel great saddness. Or hear/see amazing musicians... or breathe I guess... all the time really.
Everytime I hear a song I like, when I wake up, when I smoke, when I am tired, I play on average 4 hours a day. and that is just messing around. I break it up into four 1 hour blocks most of the time. But I still get all the practice I need to keep me where I am at. If I ever join a band I will deffinatly start practicing more. But untill then 4 hours in enough for me!
i just pick up my guitar too often, when i´m bored, when i don´t feel like doing something alse and when i feel like its time to do some guitar studying (which rarely is the case). most of the time i just make something up, i´m advanced enough to just jam the whole day and most of the time I like what i make up, but more special is that it gives me such a relaxing feeling to just jam on my own. i imagine that meditation feels like when i´m playing my guitar on my more ecstatic moments..... hmmz this sounds like i´m some kinda guitar wanker doesn´t it? mabey i sould add that i normally play the acoustic guitar...
I play piano about every other day, or sometimes if I'm real busy I might go 3 or 4, but sometimes every day for an hour or two. I play when I'm bored, sometimes I'm drawn to it and make myself late playing when I have somewhere to be. Mostly I play right before I go somewhere if I'm ready early or waiting on a ride. It's usually when I'm sitting down playing just for the fun of it that I decide to practice sometimes, but I rarely practice anymore since I quit taking lessons. I feel guilty about that sometimes. If I feel I'm in the mood to practice or that I'm sucking such ass I need to, I do. I only write when I feel the urge, which is usually when I'm sad so not as much as I used to since I've been quite happy for awhile.
when i start to think about playing and then i desire to play a lot more then when i build up the desire until i cant help it anymore i turn on my q-tron and my amp all the way up then just play aimlessly for hours or whatever i feel like but lately my dad's band has been practicing at my house and i practice with them
