The Poetic Silkiness

The Poetic Silkiness is a form of music used to commemorate important events originally devised by the elf Rayali Swelteredroared. The rules of the form are applied by composers to produce individual pieces of music which can be performed. Three speakers recite any composition of The Smile of Tweeting while the music is played on a aritha and a darala. The musical voices join in melody, counterpoint and harmony. The entire performance is extremely fast, and it is to be very soft. The melody has mid-length phrases, while the counterpoint has long phrases throughout the form. It is performed in free rhythm. Throughout, when possible, composers and performers are to use grace notes, play rapid runs and alternate tension and repose.

• Each speaker always should be delicate.
• The aritha always should feel playful. The voice uses its entire range from the strained low register to the wavering high register.
• The darala always should be merry.
• The Poetic Silkiness has a well-defined multi-passage structure: a theme, a bridge-passage and a lengthy series of variations on the theme possibly all repeated and a coda.
• The theme is voiced by the melody of the aritha, the melody of the darala and the speakers. This passage is richly layered with full chords making use of the available range. The passage is performed using the cebela scale.
• The bridge-passage is voiced by the melody of the darala, the counterpoint of the aritha and the speakers. Only one pitch is ever played at a time in this passage. The passage is performed using the datome scale.
• The series of variations is voiced by the melody of the darala, the counterpoint of the aritha and the speakers. This passage is richly layered with full chords making use of the available range. The passage is performed using the fena scale.
• The coda is voiced by the melody of the aritha, the harmony of the darala and the speakers. This passage typically has some sparse chords. The passage is performed using the atho scale.
• Scales are conceived of as two chords built using a division of the perfect fourth interval into eleven notes. The tonic note is fixed only at the time of performance. Preferred notes in the fundamental scale are named. The names are thuna (spoken thu, 1st), arazi (ar, 4th), fidale (fi, 7th) and tarathe (ta, 9th).
• As always, the cebela heptatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named aro and fathinu.
• The aro tetrachord is the 1st, the 3rd, the 7th and the 11th degrees of the fundamental perfect fourth division.
• The fathinu tetrachord is the 1st, the 3rd, the 5th and the 11th degrees of the fundamental perfect fourth division.
• As always, the datome hexatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named datha and thili.
• The datha tetrachord is the 1st, the 4th, the 8th and the 11th degrees of the fundamental perfect fourth division.
• The thili trichord is the 1st, the 7th and the 11th degrees of the fundamental perfect fourth division.
• As always, the fena hexatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named eyo and fathinu.
• The eyo trichord is the 1st, the 5th and the 11th degrees of the fundamental perfect fourth division.
• As always, the atho hexatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named aro and thili.
