First inversion : ウィキペディア英語版 | First inversion
The first inversion of a chord is the voicing of a triad, seventh chord, or ninth chord with the third of the chord in the bass and the root a sixth above it.〔Walter Piston, ''Harmony'', fifth edition, revised and expanded by Mark DeVoto (New York: W. W. Norton, 1987): p. 66. ISBN 978-0-393-95480-7.〕 In the first inversion of a C-major triad , the bass is E—the third of the triad—with the fifth and the root stacked above it (the root now shifted an octave higher), forming the intervals of a third and a sixth above the inverted bass of E, respectively. File:First inversion of C major triad.svg ==History== In early music, what is today called a ''sixth chord'' or ''first inversion'' in classical music was considered an autonomous harmonic entity with the root named by the bass, while it was later simply considered an inversion of a chord with the bass being the third (not the root) and the root being the sixth (not the bass).
