In music, the attendant keys the keys or scales most nearly related to, or having most in common with, the principal key; those, namely, of its fifth above, or dominant, its fifth below (fourth above), or subdominant, and its relative minor or major. Research Attendant Keys
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 tonicchord, 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.

In music, a key is a family of tones whose regular members are called diatonic tones, and named key tone (or tonic) or one (or eight), mediant or three, dominant or five, subdominant or four, submediant or six, supertonic or two, and subtonic or seven. Chromatic tones are temporary members of a
key, under such names as sharp four, flat seven, etc. Scales and tunes of every variety are made from the tones of a key. The name key is also given to the fundamental tone of a movement to which its modulations are referred, and with which it generally begins and ends. Its keynote.
In music, a Neapolitan sixth is a chord composed of the subdominant of the key, plus a minor third and a minor sixth. Harmonically it is equivalent to the first inversion of a major chord built upon the flattened supertonic. Research Neapolitan Sixth
