A nonchord tone (NCTs), nonharmonic tone, or embellishing tone is a note in a piece of music that is not part of the implied chord within the harmonic framework. Similarly, a chord tone is a note that is a part of the functional chord (see: factor (chord)). Nonchord tones are most often discussed in the context of the common practice period, but can be used in analysis of other types of tonal music as well.Chord and nonchord tones are defined by their membership in a chord: "The pitches which make up a chord are called ''chord-tones'': any other pitches are called ''non-chord-tones''."Kroepel, Bob (1993). ''Mel Bay Creative Keyboard's Deluxe Encyclopedia of Piano Chords: A Complete Study of Chords and How to Use Them'', p.8. ISBN 978-0-87166-579-9. Emphasis original. They are also defined by the time at which they sound: "''Nonharmonic tones'' are pitches that sound along with a chord but are not chord pitches."Benward & Saker (2003). ''Music: In Theory and Practice'', Vol. I, p.92. Seventh Edition. ISBN 978-0-07-294262-0.For example, if a piece of music implies a C Major chord, then notes CEG are members of that chord, while any other note played at that time is a nonchord tone. Such tones are most obvious in homophonic music but occur at least just as frequently in contrapuntal music."Most nonharmonic tones are dissonant and create intervals of a second, fourth or seventh", which are required to resolve to a chord tone in conventional ways. If the note fails to resolve until the next change of harmony, it may instead create a seventh chord or extended chord. While it is theoretically possible that for a three-note chord there are (in equal temperament) nine possible nonchord tones, nonchord tones are usually in the prevailing key. Augmented and diminished intervals are also considered dissonant, and all nonharmonic tones are measured from the bass, or lowest note sounding in the chord except in the case of nonharmonic bass tones.Nonharmonic tones generally occur in a pattern of three pitches, of which the nonharmonic tone is the center:1 - 2 - 3Preceding tone - Nonharmonic tone - Following tone(chord tone) - - (chord tone)Preparation - Dissonance - ResolutionNonchord tones are distinguished through how they are used. The most important distinction is whether they occur on a strong or weak beat and are thus accented or unaccented. They are also distinguished by their direction of approach and departure and the voice or voices in which they occur, and the number of notes they contain.Over time some nonchord tones supposedly became chord tones, such as the seventh in a seventh chord. In European classical music "The greater use of dissonance from period to period as a result of the dialectic of linear/vertical forces led to gradual normalization of ninth, eleventh, and thirteenth chords(analysis and theory ); each additional non-chord tone above the foundational triad became frozen into the chordal mass.""Debussy and the Crisis of Tonality", p.72.
