2. Find the interval between the root and the highest note in the chord. This interval will tell you the inversion of the chord.
Here are the different inversions and their corresponding intervals:
- Root Position: The highest note in the chord is the root. (Interval: 1 octave)
- First Inversion: The highest note in the chord is the third of the chord. (Interval: 6 half steps)
- Second Inversion: The highest note in the chord is the fifth of the chord. (Interval: 4 half steps)
For example, let's find the inversion of the chord C-E-G.
1. The root of the chord is C.
2. The highest note in the chord is G.
3. The interval between C and G is 7 half steps.
Because the interval between the root and the highest note is 7 half steps, the chord is in first inversion.
