n terms of frets, I understand you can create a tone in distance between your first and second finger of yourfretting hand, but why is it not reccomended to make a tone between the second and third if you can do it?
because you touch yourself at night
Its not completely impossible, and infact up on the high frets its easy. I think its just not so comfortable between those two fingers. But its not a rule that you can do it. Just try it and see how it feels.
Basically it's because almost everyone finds it harder to reach a tone with those two fingers than with any others.
You can, it's just not very comfortable in the lower positions.
