What type of harmony is implied by stacked chords?

Stacked chords imply a form of harmony known as "tertian harmony," where chords are built by stacking thirds on top of each other. This structure creates a sense of tonal organization and can lead to various harmonic progressions. Additionally, stacked chords can also suggest extended harmonies, like seventh, ninth, or eleventh chords, adding complexity and richness to the sound. Overall, this method of building chords forms the basis of much Western music harmony.
