inversion of seven chords

Seven chords are chords in which four tones are superimposed according to a three-dimensional relationship, and are called root, tri-tone, pentatonic and heptatonic from bottom to top.

the seventh chord has three inversions: the fifth and sixth chord (the first inversion), the third and fourth chord (the second inversion) and the second chord (the third inversion).

the first inversion-the fifth and sixth chords

a seventh chord with three notes as the lowest and the root as the highest note is called the first inversion, which is also called the fifth and sixth chord.

just like the first inversion of a triad, the root sound is moved up by an octave.

the second inversion-the third and fourth chords

the seventh chord with five notes as the lowest tone is called the second inversion, which is also called the third and fourth chord.

in the second inversion, on the basis of the first inversion, the three tones move 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 moves up by an octave on the basis of the second transposition.
