Voice leading: the shortest path between chords

Think of a chord as several melodies

When you play four notes together, you can think of them as four voices. Each voice can continue to a new note in the next chord. A progression can therefore be heard as several small melodic lines.

Voice leading is about this continuation. It is not just about which chord symbol comes next, but how the individual notes get there.

Keep what already fits

Cmaj7 contains C, E, G and B. Am7 contains A, C, E and G. Three notes are shared: C, E and G.

One possible piano transition is C–E–G–B to C–E–G–A. The three lower voices stay while B moves down a whole tone to A. The final chord is Am7 with C in the bass, or first inversion.

The nearest path is a choice

Small movements can bring calm and continuity. Larger leaps, a change of register or a new bass note may be right when you want contrast and direction. Good voice leading does not mean every voice must always move as little as possible.

On guitar, the construction of the shapes affects what is practical. A shape may double notes or omit a perfect fifth. Consider both the voices you actually play and the musical role you want to highlight.

Try treating the highest voice as a clear melodic line. It can give your chord playing its own story even when the rest of the harmony is simple.

Follow the voice you actually hear

Play C–E–G–B followed by C–E–G–A, listening only to B–A at the top. Then play this line alone. Restore the other notes and see whether you can still hear the movement as a separate melody.

On guitar, you can choose a smaller shape that makes this voice clear. The aim here is to see common tones and movement in a concrete example, rather than cover every rule of part-writing.
