In music, a passing chord is a chord that connects, or passes between, the notes of two diatonic chords. [3] "Any chord that moves between one diatonic chord and another one nearby may be loosely termed a passing chord. A diatonic passing chord may be inserted into a pre-existing progression that moves by a major or minor third in order to ...
These chords stand in the same relationship to one another (in the relative minor key) as do the three major chords, so that they may be viewed as the first (i), fourth (iv) and fifth (v) degrees of the relative minor key. For example, the relative minor of C major is A minor, and in the key of A minor, the i, iv and v chords are A minor, D ...
In equal temperament, each semitone is the same distance apart and there are four semitones between the root and third, three between the third and fifth, and seven between the root and fifth. Another tuning system that is used is just intonation. In just intonation, a major chord is tuned to the frequency ratio 4:5:6.
Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle. If the line extensions (secant lines) of chords AB and CD intersect at a point P, then their lengths satisfy AP·PB = CP·PD (power of a point theorem).
An arpeggio for the chord of C major going up two octaves would be the notes (C, E, G, C, E, G, C). In musical notation, a very rapid arpeggiated chord may be written with a wavy vertical line in front of the chord. Typically these are read as to be played from the lowest to highest note, though composers may specify a high to low sequence by ...
In just intonation, a minor chord is often (but not exclusively) tuned in the frequency ratio 10:12:15 (play ⓘ). In 12 tone equal temperament (12 TET, at present the most common tuning system in the West) a minor chord has 3 semitones between the root and third, 4 between the third and fifth, and 7 between the root and fifth.
Not including the root motion, there is only a one-note difference between a half-diminished seventh chord and a V 7 chord with a flat ninth. Since it is built on the diatonic II chord of the minor scale, most of the time the II-V pattern resolves to a minor tonic (such as in the progression D ø 7 – G 7 ♭ 9 – Cm), but there are also ...
The chord-scale system may be compared with other common methods of improvisation, first, the older traditional chord tone/chord arpeggio method, and where one scale on one root note is used throughout all chords in a progression (for example the blues scale on A for all chords of the blues progression: A 7 E 7 D 7).
