V7 chords can be a bit tricky for students because they are often introduced in many different ways. Most method books start with an easier first inversion of V7 chords that omits a few chord tones for easier playing.
This 7th chord poster makes it easier to spot the roots and intervals to identify 7th chords and their inversions.
Quick Tips for Identifying V7 Chords
- In first inversion the "root bump" is in 1st place.
- For 2nd inversion the "bump" falls to 2nd place.
- For 3rd inversion the "bump" is in 3rd place.
V7-Root Position 7th Chord
7th chords can also be identified by the intervals of the "bump notes."
7th chords in root position are easy to spot because they look like a tall snowman with four snowballs instead of the three you see stacked up in a triad. The root is on the bottom and with the highest note a 7th above it.
V6/5-1st Inversion 7th Chord
The root jumps up to the top of the chord in first inversion.
The resulting intervals are a 3rd, 5th and 6th.
The abbreviated chord symbol is V6/5
