A chord is a harmonic unit in music theory, consisting of three or more notes played simultaneously. Chords form the foundation of harmony in music and are essential for composition, performance, and analysis.
Chords are typically notated using chord symbols, such as C (C major), Cm (C minor), C7 (C dominant seventh), etc. These symbols provide a quick way to represent harmonic structures.
Triads are three-note chords consisting of a root, third, and fifth. The four main types are major, minor, diminished, and augmented triads.
Seventh chords add a fourth note to triads, creating richer harmonic textures. Common types include major seventh, minor seventh, and dominant seventh chords.
Altered chords modify standard chord structures by raising or lowering certain intervals, creating unique harmonic colors. Examples include augmented, diminished, and suspended chords.
Chord inversions rearrange the order of notes within a chord, placing notes other than the root in the bass. This technique adds variety to harmonic progressions.
