What is a chord inversion?
Unless you know chord inversions, which for this lesson I am assuming you don’t, the chords you are used to playing are all in “root position”. This means that the tonic of the chord is the lowest not (the bass note) of the chord. So, for example, in an Cmaj7 chord the bass note of the chord is C. But whenever a note other than the root (tonic) is the bass note, then the chord is an inversion. Make sense?
As you know, most chords are played with three or four notes on guitar. That means that besides the tonic, there are at least two to three other notes that can bee in the bass position. (For example a C major chord is C, E, G. Besides C there are two other notes that can be first. Cmaj7 is C, E, G, B. Besides C there are 3 other notes).
How to make chord inversions
There are three common chord inversions and they’re called first inversion, second inversion and third inversion. In first inversion the 3rd of the chord is the bass note. (It’s called first inversion because the 3rd of the chord is the first note after the tonic). In second inversion the 5th of the chord is in the bass. (Called second inversion because the 5th is the second chord tone after the tonic). And third inversion has the 7th as the bass. (Called third inversion because….well, you get the idea). Not so bad too far, is it?
The drop-two voicing
Before we look at how the three chord inversions are, this would be a good time to make sure you know what “drop-two” chord voicings are because we are going to use them to build or chord inversions to make them easy to play on guitar. So take a moment to read my post on drop-two chord voicings and them come back to this post and continue where you left of. If you already know what a drop 2 chord voicing is then just keep reading.
Playing chord inversions on guitar
Ok, back to the three Cmaj7 chord inversions. Ok. So the notes of Cmaj7 chord are C, E, G, B. So here is the standard Cmaj7 chord in root position with a drop-two voicing applied:
Now let's see the first inversion. So let’s take the root note and send it to the back of the line. So the chord spelling for first inversion would now be: E, G, B, C. But that note grouping will be hard to play on guitar, so let’s also give it the drop-two voicing. So the new note order would be E, B, C, G.
