Music theory lesson
Chords and Harmony
Stack intervals, hear chord quality, then recognize how voicing and inversion change the surface.
Chords combine pitches at the same time. Begin with root-position major and minor triads, then separate chord identity from voicing, inversion, and musical function.
Choose a focused route.
Move from broad topic to one skill, then open a stable printable set.

Open section →Notes, sources, and further reading
Read the chord, not a letter list
Use engraved chord notes to locate the root and third, identify quality, and then examine the bass note for inversion. Progress to seventh chords and cadences only after triad spelling is reliable.
