Many modern guitarists, especially rockers, deliberately limit their capabilities. Without paying attention to speed playing, accuracy and working with scales, they are deprived of the opportunity to use different styles, tempos and other important musical elements. A modern guitarist must have an excellent view of the fingerboard from the perspective of the fingering grids and be able to use them technically flawlessly, even when playing at speed. By the way, from this point of view it is very useful to listen to a wide variety of music, and not just the top twenty hit parade.
