Chords

Beginner

  1. The Major Chord

    What a major triad is, how to build one from any root note, and how to hear its bright, stable sound.

  2. The Minor Chord

    How the minor triad is built, why it sounds darker than the major chord, and the one-semitone change that makes all the difference.

Intermediate

  1. Diminished and Augmented Chords

    How diminished and augmented triads are built from stacked thirds, why both sound unstable, and where they show up in real music.

  2. Chord Inversions

    What a chord inversion is, how to recognize the same triad with a different note in the bass, and why musicians use inversions at all.
