Hi Muris!

I wanted to ask you something about left hand posture. This might seem as a stupid question but I'm a little bit confused.
When I started playing guitar I began with classic guitar. The thumb (left hand) never went over the neck, it was somewhere around the middle.
I noticed that every good player holds its thumb over the neck as much as possible.Should I try do the same? I hope you understand my dilemma I ask this because it seem to be easier to play this way when standing up.

Best regards,

Denis

Hello Denis.

I do understand your question
and the way I see things is that you should adjust your thumb
along as you play different licks or techniques on different strings and positions.
Per example, if you are playing some legato or maybe just a picking lick
using 2 whole tones near the nut you'd probably need to put
your thumb somewhere around middle of the neck or even lower,
simply because you'd feel not comfortable if it sticks over the neck.
On the other hand IMO this position with thumb at the middle of the neck (ala classical)
isn't that great for performing solid bending and applying powerful vibrato.
To do that I suggest you to move your thumb up, over the neck, to get solid grip and stand.
Bottom line, keeping it at one position all the time isn't best solution imo.

Hope this helps a little.

Tnx Murise!
Now I have an idea on what to pay attention when playing.

Pozdrav!

Anytime, pozdrav!

What about when you're doing very wide stretches? Any tip? That's a weak point for me.

As said above, wide stretched demand very low thumb position
and your wrist has to go pretty much ahead.
Now, you have to find sweet spot for your guitar, perhaps you're holding it too low?

I hold it pretty high actually, but thanks I'll have to work on that, I'm not satisfied with the stretches I can do.

Then it must have been thumb/wrist, check them out.
