Note: You'll gain the most from this article if you have a basic understanding of major and minor chords and seventh chords. If you aren't familiar with these concepts, take a look at our guides to major and minor chords and seventh chords.Chord inversions appear in practically every genre of music. They allow songwriters and composers to make a chord progression flow naturally and feel unique. In this article we'll explain what inversions are, plus concepts like the root note and root position. You'll learn when, why and how to play chord inversions on the piano. We'll also illustrate how inversions are used, with some examples from various types of music.
What are chord inversions?
A chord inversion, or simply "an inversion," is a chord whose notes have shifted around so that the lowest note — called the bass note — is no longer the root note.The root note is the primary note that a chord is built upon and named after. It feels natural, whereas inverted chords often evoke a sense of tension or movement. As an example, here is a C major chord, with the root note (C) highlighted:In this example, the C major chord is in its root position. This means that the lowest note of the chord is also its root note.
How do you form and play chord inversions?
When you take the root of a chord and shift it up an octave, this gives you a new order of notes for the chord, called the first inversion. To form the first inversion of a C major chord, you shift the C up an octave so that E becomes the new bass note. Now the note order is E, G, C.You can repeat this process to create yet another arrangement of the notes. If you shift the E up an octave so that G becomes the new bass note, this gives you the second inversion of the C major chord. Now the note order is G, C, E.
The number of possible inversions a chord has depends on how many notes it contains: There is one possible inversion for each note that is not the root note. So, the C major triad (three notes) has two inversions besides the root position, while an A7 chord (four notes) has three inversions, and a G9 chord (five notes) has four inversions.Why does the C major triad only have two inversions? It's best to explain this by trying to form the third inversion and seeing what happens. Following the pattern above to form the third inversion, we take the bottom note of the second inversion and shift it up an octave:
Now we've ended up with C major in its root position again, only an octave higher. So for triads, there is no third inversion.In popular music, an inversion is most commonly written as the name of the root chord followed by a forward slash (/), then the bass note in that inversion. So C major first inversion is C/E and C major second inversion is C/G.If you were to say this out loud — for example during band practice — you would say "C over E" or "C over G."
