Same three notes, different bass note, completely different sound. A C major triad in root position (C-E-G) sounds grounded. Put E in the bass (first inversion) and it sounds lighter, more flowing. Put G in the bass (second inversion) and it has an open, suspended quality. Inversions are how you create smooth chord motion without jumping around the neck.
The Three Positions
| Inversion | Bass Note | Order (bottom up) |
|---|---|---|
| Root Position | Root | Root in the bass (1-3-5 from bottom). |
| 1st Inversion | 3rd | 3rd in the bass (3-5-1 from bottom). |
| 2nd Inversion | 5th | 5th in the bass (5-1-3 from bottom). |
Inversions are the foundation of voice leading. Instead of jumping to a distant fret for the next chord, you pick the inversion that keeps your hand close to where it already is. The notes move by small intervals. The music sounds connected rather than choppy.

Select a root, triad type, and inversion to see the voicing shapes. The highlighted note in the bass is the inversion's bottom note.

The Fourths Tuning Advantage
Each inversion shape is consistent across all string groups. A first-inversion major triad on strings E-A-D uses the same fingering on A-D-G, D-G-C, or G-C-F. Three shapes per triad type (root, 1st, 2nd) give you full coverage of the entire neck.
Practice
Cycle Through Inversions
Pick a root and play root position, first inversion, and second inversion on the same string group. Listen to how the bass note changes the chord's character even though the pitch content is identical.
Voice Leading Exercise
Play C major in root position. Now move to F major using the inversion that keeps your hand closest. The E (3rd of C) sits right next to F (root of F), so first inversion of F connects with minimal movement. Try the same approach for C to Am, C to G. Find the path of least resistance.
