Transposition of the seventh chord
The seventh chord is a chord formed by the superposition of four tones according to the three-dimensional relationship, which is called root tone, three tones, five tones and seven tones from bottom to top.
The seventh chord has three inversions: the fifth and sixth chords (the first inversion), the third and fourth chords (the second inversion) and the second chord (the third inversion).
The first inversion-the fifth and sixth chords
The seventh chord with three notes as the lowest note and the root as the highest note is called the first inversion, also called the fifth and sixth chord.
Just like the first inversion of a triad, it moves the root up an octave.
The second transposition-the third and fourth chords
The seventh chord with the pentatonic scale as the lowest note is called the second inversion, also called the third and fourth chords.
The second transposition, on the basis of the first transposition, moves the three tones up by an octave.
The third inversion-the second chord
The seventh chord with seven notes as the lowest note is called the third inversion, also called the second chord, and is marked with 2.
The third transposition means that the pentatonic scale moves up an octave on the basis of the second transposition.
