Не знаю, постил ли кто-либо вот это, так что если боян, звиняйте. Это вольный пересказ метода Аллана Холдсворта со слов Пеббера Брауна, выдающегося американского педагога по джазовой импровизации, который дружен с Холдсвортом и несколько раз бывал у него дома, где и перенял его методику:
"His system of scales is based on 3 octave chromatic scales with the notes numbered 1 through 36. He thinks of scales in a minimum of 5 notes and a maximum of 10 notes per scale. He then writes out all the possible combinations of 5, 6, 7, 8, 9 and 10 note scales and throws out “any scale that’s got more than three half steps in a row,” and has created a 6 inch thick scale book he calls “The Phone Book from Hell.” His chordal concepts are similarly based and he uses 2 concepts; one to write out all the possible groups of 3, 4 5 and 6 note chords. To simplify it, in terms of a major scale he doesn’t consider the 1-3-5 triad to be the holy grail - 33 - but takes the scale 1-2-3-4-5-6-7 and then would group 3 note chords as 1-2-3, 1-2-4, 1-2-6, 1-2-7, 1-3-4, 1-3-5, 1-3-6, 1-3-7, 1-4-5, 1-4-6, 1-4-7, 1-5-6, 1-5-7, 1-6-7, etc, and write out all possible
inversions on all 3 note stringsets (similar to Pat Martino except Pat didn’t use these types of note clusters as chords). Holdsworth also does this with 4, 5 and 6 note chords and then stacks them into
mathematical polychords as his secondary method. Third, he modifies the stacked polychords by raising and lowering chord tones to obtain different colors. It can get very involved and complex very quickly and it would probably take me a life time to work it all out. He already has and uses this method in all of his
work."
