Chord Inversion Calculator
Calculate chord inversions by rearranging the order of notes. Understand how inversions change the bass note and chord voicing.
Root Position
C - E - G
Bass Note: C
Notes: CEG
How to Use This Calculator
- Select the root note of the chord.
- Select the chord type (Major, Minor, 7th, etc.).
- Choose the inversion (Root Position, 1st, 2nd, or 3rd Inversion).
- The calculator displays the inverted chord with the new bass note and note order.
Chord Inversion Formula
Inversions rearrange chord notes by moving the lowest note up an octave:
1st Inversion: 3rd - 5th - Root (e.g., E-G-C)
2nd Inversion: 5th - Root - 3rd (e.g., G-C-E)
3rd Inversion: 7th - Root - 3rd - 5th (e.g., B-C-E-G for C7)
Example: C Major in root position is C-E-G. In 1st inversion, it becomes E-G-C (E in the bass).
Full Description
Chord inversions are a fundamental concept in music theory and composition. An inversion rearranges the order of notes in a chord, putting a different note in the bass (lowest position). This changes the chord\'s sound and harmonic function while keeping the same chord name and quality.
Inversions are created by taking the lowest note and moving it up an octave. Root position has the root in the bass, 1st inversion has the 3rd in the bass, 2nd inversion has the 5th in the bass, and 3rd inversion (for 7th chords) has the 7th in the bass. Each inversion has a distinct sound and is used for different musical purposes.
This calculator helps you understand and calculate chord inversions. Select a chord and inversion, and it shows you the note order and bass note. Use it to learn music theory, create smoother chord progressions, or understand how inversions affect the sound of chords. Inversions are essential for creating professional, flowing chord progressions.
Frequently Asked Questions
What is a chord inversion?
A chord inversion rearranges the order of notes in a chord, putting a different note in the bass (lowest note). Root position has the root in the bass, 1st inversion has the 3rd in the bass, 2nd inversion has the 5th in the bass.
Why use chord inversions?
Inversions create smoother voice leading between chords, add variety to chord progressions, and create different harmonic colors. They're essential for creating flowing, professional-sounding chord progressions.
How do I notate chord inversions?
Root position: C (or C/E for slash chords). 1st inversion: C/E (C chord with E in bass). 2nd inversion: C/G (C chord with G in bass). 3rd inversion: C7/Bb (C7 chord with Bb in bass).
Do inversions change the chord name?
No, inversions don't change the chord name—C Major is still C Major whether it's root position or inverted. However, the bass note changes, which affects the chord's sound and function in a progression.
