Practicing in modern times is much more complex than in previous eras due to our many technological distractions. As a result, concentration is constantly being pulled from the present. 

The problem with so many distractions is that the human mind is not multitasking. We throw the term multi-taking around in modern times in the way of handling a lot at once. 

But, the reality is our minds don't adapt to multi-taking when trying to study information or practice. Our minds don't multitask as much as they switch channels. But, when switching channels, it takes a second or two to adjust to the change. We can only do one thing at a time and focus on each independently. 

At some point, almost every guitar player asks how to play the blues scale. Discussing the notes of the scale is easy, but the fingering and position can become a point of contention for many guitarists.

Why is the position and fingering of the blues scale so controversial? Part of the problem lies in the design of the instrument. The guitar can play the same pitch in different neck positions, making learning music more challenging. Finding the pitch, listening to phrasing, and considering positioning is necessary when learning music for the guitar.
