Path
What to study before Chord inversions
The same notes over a different bass: the same identity with a different weight and a different voice leading. Below, the concepts that come before, in the order in which one explains the next. Signed in, you see the same path minus what you already hold: your path.
Notes and semitones
The seven letter names, the accidentals that alter them, and the semitone as the system's smallest step.
Intervals
The distance between two notes, measured by a number taken from the letter names and a quality taken from the semitones.
Triads
Three-note chords stacked in thirds, and the four qualities that result.
