C7 Chord Inversions: All Four Positions

To invert C7, move the lowest note up an octave: C E G Bb becomes E G Bb C, then G Bb C E, then Bb C E G. Learn to spot each position at a glance, then use the nearest one to move between chords.

Spot each C7 inversion in one look

One rule: find the pair of neighbouring notes. Its place tells you the inversion, and its upper note is the root.

Four notes, four fingers: 1-2-3-5 in the right hand and 5-3-2-1 in the left work in every position.

C7 in a ii-V-I with inversions: Gm7 → C7 → Fmaj7

Each chord uses the position nearest to the one before, so the hand barely moves and most notes step by one or two keys.

Fmaj7 A C E F
  • From Gm7 to C7: Bb stays, D → C, F → E, G stays.
  • From C7 to Fmaj7: Bb → A, C stays, E stays, G → F.

Common questions

How many inversions does C7 have?

Four positions in total, because it has four notes: root position plus three inversions, C7/E, C7/G and C7/Bb.

How do I recognise the 3rd inversion of C7?

The seventh, Bb, is in the bass and sits right next to the root C above it: the pair of neighbouring notes is at the bottom.

Can I practise C7 inversions with a MIDI keyboard or microphone?

Yes. ChordRunner detects a USB MIDI keyboard automatically and also hears a piano through the microphone; every inversion of C7 counts.

Your instrument is the controller.

ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
