Path

What to study before Suspended chords

The third replaced by the fourth or the second, which leaves the chord neither major nor minor. 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.

Properties of sound
The four properties every musical sound has at once: duration, intensity, pitch and timbre.

Triads
Three-note chords stacked in thirds, and the four qualities that result.
Level 2has practicelesson Three notes, four chords (First steps in theory)
Seventh chords
The fourth note stacked on the triad, and the five qualities the repertoire actually uses.

Chord symbols
The notation that names a chord by its root and quality, and how to read its extensions and alterations.
