the chord quality (e.g. minor or lowercase m, or the symbols o or + for diminished and augmented chords, respectively; chord quality is usually omitted for major chords) whether the chord is a triad, seventh chord, or an extended chord (e.g. Δ 7) any altered notes (e.g. sharp five, or ♯ 5) any added tones (e.g. add2)
6 semitones (augmented fourth, tritone, or diminished fifth): Augmented-fourths tuning, 7 semitones (perfect fifth): All-fifths tuning; For the regular tunings, chords may be moved diagonally around the fretboard, as well as vertically for the repetitive regular tunings (minor thirds, major thirds, and augmented fourths). Regular tunings thus ...
In modal tunings, the strings are tuned to form a chord which is not definitively minor or major. These tunings may facilitate very easy chords and unique sounds when the open strings are used as drones. Often these tunings form a suspended chord on the open strings. A well known user of modal tunings is Sonic Youth. Asus2: E-A-B-E-A-E
This works because diminished seventh chords are structurally equivalent in all of their inversions (a stack of minor thirds), so any note in a diminished seventh chord can be seen as the root note. The most important irregular resolution is the deceptive cadence , [ 3 ] most commonly V 7 –vi in major or V 7 –VI in minor.
In dominant function, the VII half diminished chord, like its fully diminished counterpart, can take the place of the dominant V chord at a point of cadential motion. This chord, sometimes called a leading-tone diminished seventh chord , is represented by the Roman numeral notation vii ø 7 , the root of which is the leading-tone to the tonic ...
The leading-tone diminished triad and supertonic diminished triad are usually found in first inversion (vii o 6 and ii o 6, respectively) since the spelling of the chord forms a diminished fifth with the bass. [6] This differs from the fully diminished seventh chord, which commonly occurs in root position. [8]
Only the intervals of a second, third, sixth, and seventh (and the compound intervals based on them) may be major or minor (or, rarely, diminished or augmented). Unisons, fourths, fifths, and octaves and their compound interval must be perfect (or, rarely, diminished or augmented). In Western music, a minor chord "sounds darker than a major ...
However, a B diminished chord (B, D, F) may not be tonicized because "B diminished" could not be a stable key area; there is no key area in Western classical music that has B, D, & F—the pitches that make up the B diminished chord—as the first, third and fifth scale degrees, respectively. This holds true of all diminished and augmented chords.
