FEMININE RHYME
A cell possesses a Feminine Rhyme if its Beat's note-value is subdivided, usually in two equal parts.

FIFTH
Tr- Distance, in the Quantitative Dimension of Pitch (frequency), see Interval

FIFTHS (SERIES OF)
The fundamental structure of the World of Pitch in which all the notes are strung together, like a string of pearls, each at a distance of a perfect fifth from the others.

FIFTEENTH
Tr- Distance, in the Quantitative Dimension of Pitch (frequency) see Interval

FISSION
A generative procedure in Melo-rhythm in which a cell is split, producing an Off-beat identical to the Beat, with a breath between the two.

FLAT
1. A chromatic semi-tone lower. 2. Symbol which designates a chromatic semi-tone lower.

FOOTSIES
Alternating movement of the feet (and balancing of the body), at any rhythmic level, to denote the Beats (on the right foot) and the Off-beats (on the left foot). see Beat and Off-beat

FOURTH
Tr- Distance, in the Quantitative Dimension of Pitch (frequency) see Interval

FOURTEENTH
Tr- Distance, in the Quantitative Dimension of Pitch (frequency) see Interval

FRAME (OF A CHORD)
Composed of the 2 Primary Notes of the chord (the root and the fifth) in which one note will be the COMMON TONE and the other the PROPER TONE, depending on the direction of the chord's resolution.

FREQUENCY
Quantitative Dimension in the World of Pitch (measured in hertz)

FUNCTION
The role which en element plays within its immediate surroundings
     in harmony, usually a note in a chord, or a chord in a diatonic system, and
     in rhythm, the nature of Alternation at any given moment.
In a generative approach, all notes (and chords) are functional (both rhythmically and harmonically).
     see Chordal Function and Tonal Function and see Alternation
.

FUNCTIONAL TUNING
Just Intonation Tuning in which each note is tuned according to its harmonic (and possibly melodic) function -
     FRAME notes (COMMON TONE and PROPER TONE) and MOTRIXs will be tuned in Trunk Tuning
     MEDIANs (diatonic and chromatic) will be tuned in Short Branch Tuning,
          major medians one comma lower, minor medians one comma higher than Trunk Tuning
     Chromatic MOTRIXs will be tuned in Long Branch Tuning,
          diminished sevenths 2 commas higher and augmented sixths 2 commas lower than Trunk Tuning
     Melodies are usually tuned in Trunk Tuning

FUSION
A generative procedure in Melo-rhythm in which two (or more) cells are joined into one Entity.
