Triads (or any other tertian chords) are built by superimposing every other note of a diatonic scale (e.g., standard major or minor scale). For example, a C major triad uses the notes C–E–G. This spells a triad by skipping over D and F. While the interval from each note to the one above it is a third, the quality of those thirds varies ...
Euler's Tonnetz. The Tonnetz originally appeared in Leonhard Euler's 1739 Tentamen novae theoriae musicae ex certissismis harmoniae principiis dilucide expositae.Euler's Tonnetz, pictured at left, shows the triadic relationships of the perfect fifth and the major third: at the top of the image is the note F, and to the left underneath is C (a perfect fifth above F), and to the right is A (a ...
The Harmonic Table note-layout, or tonal array, is a key layout for musical instruments that offers interesting advantages over the traditional keyboard layout. Its symmetrical, hexagonal pattern of interval sequences places the notes of the major and minor triads together.
In the lower stave the notes E ♮ and B ♭ are given. These form a tritone which defines the dominant sound, and are the major 3rd and minor 7th of the C 7 ♯ 9 chord. In the upper stave the notes E ♭, G, and B ♭ are given together: these form an E ♭ major triad.
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.
In a minor key triads i and iv are minor chords, but in chord V the leading-tone is generally raised to form a major chord. [2] For example, in A minor the primary triads are Am, Dm and E. Chord v (minor) in a minor key might be expected to be a primary triad, but its use is rare in common practice harmony.
The root position of a chord is the voicing of a triad, seventh chord, or ninth chord in which the root of the chord is the bass note and the other chord factors are above it. . In the root position, uninverted, of a C-major triad, the bass is C — the root of the triad — with the third and the fifth stacked above it, forming the intervals of a third and a fifth above the root of C, respective
A minor triad is represented by the integer notation {0, 3, 7}. A minor triad can also be described by its intervals: the interval between the bottom and middle notes is a minor third, and the interval between the middle and top notes is a major third. By contrast, a major triad has a major third on the bottom and minor third on top.
