To calculate the Chord Inversion (CI):
\[ CI = (N + I) \mod 12 \]
Where:
A chord inversion is a rearrangement of the notes within a chord in which the note in the bass (the lowest note) is not the root of the chord. In other words, it is a chord that has been rearranged so that a note other than the root is the lowest note. This is typically done to create a different sound or to facilitate smoother transitions between chords. For example, in a C major chord (C-E-G), the root is C. If we rearrange the chord so that E is the lowest note (E-G-C), we have the first inversion. If we rearrange it so that G is the lowest note (G-C-E), we have the second inversion. Each inversion creates a different voicing, or arrangement of the chord’s notes, which can give the chord a different sound or character.
Let's assume the following values:
Using the formula:
\[ CI = (0 + 1) \mod 12 = 1 \]
The chord inversion value is 1, which corresponds to C#.
