Hi. I taught myself to play when I was a youth who knew everything. I had fun, but eventually stopped, and took 15 years with my guitar locked in its case. I'm starting again now, with a little more humility.

I've started watching the 'fundamentals 1' videos, and I notice a few areas in which the way I feel comfortable is different to the technique demonstrated. If it makes a difference at all, I'm on an electric.

1) left thumb position. Lisa talks about using the strength of the opposable thumb. I do this, but the pad of my thumb is pressing more in line with the centre of the back of the neck, not peeping (or even wrapping) over the top as it is in the videos.

If I try and match this position, I find my fingers feel a lot less mobile around the fretboard, and the geometry of my hand just doesn't create a firm bar (it's hard to get my index finger straight and across all 6 strings with my thumb in that position).

2) Pick grip. In addition to holding it between my thumb and 1st finger, I've been putting my 2nd finger on the side of the pick. Just feel a little more control.

3) I can't get comfortable playing sitting down. With my right leg nested into the curve of the guitar, it feels like the guitar is too far to the right, and I'm stretching my right arm out to play? (this one isn't too big an issue as I'm comfortable standing for long periods)

4) Instead of keeping my right wrist rigid and pivoting off the top of the guitar, I've been allowing a little wrist movement, and letting my forearm just above my wrist rest lightly against the guitar, somewhere near the bridge. There's still more pressure in the 'correct' pivot point closer to my elbow, and the bit nearer the wrist that rests on the guitar isn't stationary, but it's not quite as described. I'd say that for strumming, about 65% of my motion comes from the elbot pivot, 35% from the wrist movement. For anything more detailed (lead melodies, picking), the balance moves more towards wrist movement.

Am I good to carry on with these quirks, or do I need to break myself out of it now? And if I need to change number 1, I'll need some tips on that - the videos I've reached so far don't seem to cover it, or my hand just don't fit on a guitar the same way the same as most.
