A minor triad has a minor third (m3) on the bottom, a major third (M3) on top, and a perfect fifth (P5) between the outer notes. In harmonic analysis and on lead sheets, a C minor chord can be notated as Cm, C−, Cmin, or simply the lowercase "c". A minor triad is represented by the integer notation {0, 3, 7}.
minor triads contain a minor third with a major third stacked above it, e.g., in the minor triad A–C–E (A minor), A–C is a minor third and C–E is a major third. diminished triads contain two minor thirds stacked, e.g., B–D–F (B diminished) augmented triads contain two major thirds stacked, e.g., D–F ♯ –A ♯ (D augmented).
Minor major seventh chord. A minor major seventh chord, or minor/major seventh chord (also known as the Hitchcock Chord) is a seventh chord composed of a root, minor third, perfect fifth, and major seventh (1, ♭ 3, 5, and 7). It can be viewed as a minor triad with an additional major seventh.
In music, a minor seventh chord is a seventh chord composed of a root note, a minor third, a perfect fifth, and a minor seventh (1, ♭ 3, 5, ♭ 7). In other words, one could think of it as a minor triad with a minor seventh attached to it. [2] For example, the minor seventh chord built on A, commonly written as A− 7, has pitches A-C-E-G:
Other scales with a minor third and a perfect fifth (i.e. containing a minor triad) are also commonly referred to as minor scales. Within the diatonic modes of the major scale, in addition to the Aeolian mode (which is the natural minor scale), the Dorian mode and the Phrygian mode also fall under this definition.
This triad is consequently called the supertonic diminished triad. Like the supertonic minor triad found in a major key, the supertonic diminished triad has a predominant function, almost always resolving to a dominant functioning chord. [7] If the music is in a minor key, diminished triads can also be found on the raised seventh note, ♯ vii o.
The circle of thirds is closely tied to the diatonic scale. Every note on the circle of thirds that starts a minor triad or minor 7th chord starts a sequence of 7 notes that belong to a Dorian scale. For example the sequence DFACEGB in the circle of thirds contains all the notes in D Dorian and D Dorian's associated modes.
The A minor triad is in dark blue, and the C major triad is in dark red. Interpreted as a torus, the Tonnetz has 12 nodes (pitches) and 24 triangles (triads). In musical tuning and harmony, the Tonnetz (German for 'tone net') is a conceptual lattice diagram representing tonal space first described by Leonhard Euler in 1739. [1]
