TABLES
Mostly used in Just Intonation to give accurate tunings listed (a) construction of the harmonic system, (b) placed in order of pitch (ascending or descending), and (c) the natural harmonics.

TAIL

TEMPERATURE
seeChrominicism

TEMPERED TUNING
seeIntonation

TENANT CHORDS
One of thetransformationsin Melo-Harmony.

TENDENCY
The "desire" of a note to rise or to fall to the following note: (a) on a large level (that of the Window of the diatonic system), according to its Chrominicism, and (b) on a smaller level (that of the chord involved), according to the Voice-leading of its specific Orbit. See theComments and Questionspage.

TENTH

TERNARY

TIMBRE
Qualitative Dimension in the World of Energy, proportion of the volume of the natural harmonics to that of the fundamental tone

TIME
One of the 3 Worlds of Music - its Quantitative Dimension is Duration of a note (or chord) and its Qualitative Dimension (at any specific moment) is found in the Alternation of Beat and Offbeat at all levels of Duration.

TONIC
The chord in the center of the nucleus (the group of 3 similar-mode chords, of the same mode as that of the tonality)

TONAL FUNCTON
Each Tonal System (within a Window) contains seven chords with distinct Tonal Functions
     Within the nucleus of the Tonal System (the three chords of the same mode as that of the system)
          The TONIC chord in the center of the three
          The DOMINANT chord beside the TONIC, at the center of the Window
          The COUNTER (Subdominant) chord on the other side of the TONIC, at the extremity of the Window
     Within the Tail of the Tonal System (the three chords of opposite mode to that of the system
          The ANTE-1 placed next to the DOMINANT
          The ANTE-2 placed next to the ANTE-1
          The ANTE-3 placed next to the ANTE-2, at the extremity of the Window
     Joining both extremities of the Window to complete the Circle
          The "Buckle" chord which has a smaller FRAME
               (a diminished fifth, between the sharpest and flattest notes of the system)
