質問: An interesting three-note chord is the following on guitar (in standard tuning): ``` ╫───╫───╫───╫───╫───╢ E ╫───╫───╫───╫───╫───╢ A ╫─G─╫───╫───╫───╫───╢ D ╫───╫─B─╫───╫───╫───╢ G ╫─E─╫───╫───╫───╫───╢ B ╫───╫───╫───╫───╫───╢ e As a Gmaj6 (no 5) interpretation: ╫───╫───╫───╫───╫───╢ E ╫───╫───╫───╫───╫───╢ A ╫─1─╫───╫───╫───╫───╢ D ╫───╫─3─╫───╫───╫───╢ G ╫─6─╫───╫───╫───╫───╢ B ╫───╫───╫───╫───╫───╢ e As an Emin (first inversion) interpretation: ╫───╫───╫───╫───╫───╢ E ╫───╫───╫───╫───╫───╢ A ╫♭3─╫───╫───╫───╫───╢ D ╫───╫─5─╫───╫───╫───╢ G ╫─1─╫───╫───╫───╫───╢ B ╫───╫───╫───╫───╫───╢ e ``` This seems chameleon-like in that it appears to be both major and minor at the same time. Is one of these interpretations wrong, or does it simply depend upon the context? EDIT: My graphics above are intended to represent a six-string fretboard, with the strings labelled to the far right. The numbers represent my interpretation of the notes. Let's suppose that the notes, in ascending order, are G, B, and E. The top graphic illustrates the named notes. The middle graphic illustrates those notes as the root (1), the major third (3), and the sixth (6) which together yield what I am calling a Gmaj6 (with the 5 omitted). The bottom graphic illustrates the same notes as a minor third (b3), fifth (5), and root (1) of a Emin triad in the first inversion.
回答: althought the chord starts with a G note, the result has got a minor quality, so I would say it's a minor triad inversion. Also because it's easier to understand music if you "feel" the sound instead of trying to rationalize everything- the sixth of the G (E) , here, is virtually useless, from the G Major 's point of view (if chords could talk, I mean...)
