Обращение аккордов: подскажите пожалуйста Опции

Чувки, давно и безутешно ищу эту схему.. помогите плиз

Олдос Хаксли "А меня вот ... Долой терцию!" Это наверно вот почему: "The G (and B) string drives people crazy on the guitar. They tune it, then play a C chord or A minor chord, but the G string sounds wrong. Fuzz and distortion makes the wrongness even more apparent. So they tune the G string by ear so that chord is in tune... and then all the other chords they play sound wrong. Way down there at the first fret, all your intonation acrobatics (which mostly affect the other end of the string!) will be of little use, so what do you do? Sigh wearily... and look for another guitar, which might fix the problem... sorta. The explanation won't make you happy. In the "first position," meaning for chord shapes that are mostly on the first couple frets on the guitar, the G string is often used for the upper part of a musical interval called a "third," either major or minor third. (This musical term is not to be confused with "third harmonics;" it's a totally different thing.) In an ideal world, a "major third" is two notes (a "diad") whose frequencies are in a ratio of 5 to 4, or 1.25, while a "minor third" is in a ratio of 6 to 5, or 1.2. If those ratios are true, these diads (note pairs) sound wonderfully in tune and harmonious. Here's where it gets hairy. In our 12-tone Western scale, where all the notes are equally spaced, no pair of them are exactly in a 1.2 or 1.25 ratio. If you pull out your calculator and multiply 1.05946 by itself a few times, you'll land on 1.189 and, next, 1.2599! The first one is actually 15 cents flat from where your ears will want a minor third to be, and the second is 14 cents sharp from where a major third should be! So if you tune a chord that includes a major third "by ear" until it sounds perfect, that same chord with a minor third substituted in it will be 29 cents out of tune... almost a third of a half-step. (Cue: wailing and gnashing of teeth.) For comparison, a "fourth," the frequency span from A down to E, should be in a ratio of 4 to 3, or 1.3333... but in our Western scale, it lands on 1.3348. Damn close... but still 2 cents sharp. A "fifth" (E to B, the ultimate punk rock interval; one string over, 2 frets up) should be 3 to 2, or 1.5000, but it lands on 1.4983 in our scale... 2 cents flat. (Yeah, close enough for rock and roll.) But... pile on a bunch of fuzz/distortion (which nakedly reveals tuning problems) and place those "third" notes right on the pesky first fret of the guitar, and you can have the ultimate homicidal-suicidal tuning nightmare. There's not much you can do. When a musician with a song including lots of first position complex chords notices this problem, he (and you) can go nuts trying to get his guitar in tune. There are actually chord progressions that simply cannot be played completely in tune on some guitars, period; you have to tune by ear for part of the chord progression, record it, then retune for the other part of the chord progression, and punch all those parts in... with very fast fingers. Or get another guitar... and hope!" полная статья здесь: http://www.endino.com/archive/tuningnightmares.html . Очень советую всем к прочтению.
