CADENCE
A progression of chords giving an effect of closing a phrase

CELL (RHYTHMIC)
see Rhythmic Cell

CHORD
A vertical, simultaneous array of notes. see Triad and Tetrad, often used to represent a specific sonority rather than a tonal function.

CHORDAL FUNCTION
Each Tetrad has 4 distinct Chordal Functions, divided in 2 groups
     The Primary Notes of the FRAME (the root and the fifth)
          The COMMON TONE which is common to both chords of the progression
          The PROPER TONE, the other note of the FRAME
     The Secondary Notes
          The MEDIAN (the third) which is placed inside the FRAME
               and which determines the mode (major or minor) of the chord
          The MOTRIX (the seventh or sixth) which is placed outside of the FRAME
               and which determines the resolution-direction of the chord

CHORD PATTERNS
A rhythmically and tonally structured series of chords, essential to Melo-harmony

CHORD PROGRESSIONS
A system of numbering, cataloguing the 9 progressions of the nucleus of a mode.

CHORD SYMBOLS
A kind of shorthand extensively used in American popular music, which we have extended in view of representing the true nature of each chord (maintaining its original identity while depicting its various transformations)

CHROMATIC NOTES
All notes placed ouside of the diatonic Window

CHROMATICISM
A Transformation in Harmony in which one (or several) member(s) of a chord are chromaticized (made sharper or flatter).

CHROMINIC
Related to Chrominicism.

CHROMINIC POSITION
The position of a note or chord on the Chrominic Scale.

CHROMINIC SCALE
Measurement scale for Chrominicism, used to quantify Chrominic Positions and relative sharpness and flatness with a measurement unit of 1/84th of an octave

CHROMINICISM
Qualitative Dimension in the World of Pitch (measured in notches of 1/84 of an octave). It is also a form of mini-chromaticism, presented in Chrominicism. It is also described as a relative Temperature of notes and chords.

CLUSTERS
Chords in which the eventual disposition (after Transformations) is tighter and the sonority more discordant than in its original, basic state. see Sonorities

COLOR
Color is used extensively on this site to denote (1) smaller or larger rhythmic levels, (2) the 4 chordal functions in harmony, (3) different forms of tuning.

COMMON TONE
The note common to both chords of a progression. see Chordal Function

COMPARTMENT
See Melo-rhythmic box

COMPOSING
