1. Versatility Many guitarists are desperate when they can not provide employment for a sufficiently long period time (for example, an hour or more daily). I often get letters from students such as' Tom, I just have to practice 20 minutes a day, and I want to play the guitar as soon as possible and as much as possible. What should I do? ". (Similarly see: Ali Partovi). In such cases, I advise you to practice exercises, which have a high level of 'universality'.
Skill is a 'universal' if you work on it simultaneously helps you to develop other methods of playing (for example, the technique of his left hand, right hand technique, the synchronization of hands, the transition between the strings, muffling the strings, the knowledge of notes on the fretboard, improvisation, etc.). If working off some skill helps more than one direction at a time, then this element has a certain degree of universality. The degree of universality of skill is determined by two main factors. The first factor – the number of tricks that he helped develop at the same time. Second – how effectively he can do it.
One example of a technology with a high degree of universality – that pass strings. It includes techniques for both hands, working out helps sihnronnoy of hands, and makes you focus on silencing unwanted sound of other strings. This technique should work, because work on it helps to improve the performance of several different technical elements. Here, for example, Legato has a much lower degree of universality.
