Diameter is the straight line drawn through the centre of a circle, and touching the two opposite points of the circumference. It thus divides the circle into two equal parts, and is the greatest chord. The length of the diameter is to the length of the circumference of the circle as 1 to 3.14159265..., the latter number being an interminable decimal.

In music, anticipation describes the commencing of one or more tones of a chord with or during the chord preceding, forming a momentary discord.

In music, arpeggio is the production of the tones of a chord in rapid succession, as in playing the harp, and not simultaneously.

In music, cadence is the name given to the closing - usually last two - chords of a phrase. The varieties of cadence may be grouped as perfect, imperfect and interrupted. The perfect must have its last chord on the tonic. When the penultimate chord is on the subdominant it is called an 'authentic'; when on the dominant, a 'plagal' cadence. The harmony of the imperfect is often that of the perfect reversed. The interrupted is a progression of chords leading the ear to expect a tonic chord, but another is substituted for the latter; the effect is often as charming as it is unexpected.
Research Cadence
In music, a chord is the simultaneous combination of different sounds, consonant or dissonant. The common chord consists of a fundamental or bass note with its third and fifth. When the interval between the bass note and its third is two full tones the combination is a major chord; when the interval is a tone and a half the combination is termed a minor chord; when the intervals between the bass note and its third and the third and the fifth are each a tone and a half, the chord is called diminished. The tonic chord is made up of the key-note and its third and fifth; the dominant chord consists of the dominant or fifth of the scale accompanied by its third and fifth; the subdominant chord has for its root or bass the subdominant or fourth of the scale, accompanied with its third and fifth.
Research Chord
In music a close harmony is a compact harmony, in which the tones composing each chord are not widely distributed over several octaves.
Research Close Harmony
In music a common chord is a chord consisting of the fundamental tone, with its third and fifth.
