Chord transposition:
Besides the root sound, the D9 chord has two notes (three notes and five notes), so it can have two inversions, three notes are the lowest notes, which are called "the first inversion" and five notes are the lowest notes, which are called the second inversion. After the first transposition of the D9 chord, it has a new name, called "the sixth chord". This is because the relationship between the three lowest notes and the root note (the highest note) is six degrees at this time, so it is named "Six Chords", and the Arabic numeral 6 is still used as the mark when notation is made.
When the fifth note of the D9 chord is at the lowest pitch, it is called "double inversion", and the double inversion of the D9 chord is called "46 chord". This is because the relationship between the fifth note with the lowest pitch and the root note is four degrees, and the relationship between the third note and the root note is six degrees, so it is named "46 chord". When labeling, Arabic numerals, 4 and 6 are still used, but the writing method is 4 at the bottom and 6 at the top.
