I teach guitar, I made myself my own methods, having learned much alone after a few years of classical guitar. So, today I look for ways to enrich my classes, and it is less intuitive than I read. Nothing is left to intuition. This is the very school learning, academic. This is not an evil, but not my thing. The method focuses on reading notes (not mandatory, but interesting). By cons, reading is difficult, printing, and the characters are not terrible, when we want to play chords into notes, it gets hard. The exercises are quite basic and melodically, uninteresting. Level ranges, it seems to me that it is filling. All being transposed to guitar, why detail each tone major scale, instead of just saying that it is enough to move one space to increase the tone of half tone? Without that method would 50 pages, and could not be sold so dear. An interesting method to improve reading notes, but the author leaves fast enough for granted everything it addresses. This is challenging but yet it does not go very far nor the bottom of things, news are seen on the surface and we go immediately to another without any real explanation, like the difference between styles ... Actually all the exercises are similar, and apart from the strings breaks, it is almost all the time of consecutive notes (except for one financial year to the end).
In the end I bought methods to find new avenues for teaching my students (because everyone understands differently, and we need to find some things to help!), But this is austere, lack of clarity, which makes the main attraction of a method. If you want to learn, so much prefer the methods of Jean-Jacques RĂ©billard with the same explanations of the notes, the rhythm (much further), styles, chords, scales, and especially with optimum clarity, and j ''ve tried methods! Take complement 'Agreements for Dummies', awesome, and 'Exercises for Dummies', which despite the name, and without writing Berklee above, much better way to address ranges, with more complex fingerings. Never trust the name and fame!
