The Periwinkle of Ringing
The Periwinkle of Ringing is a devotional form of music originally devised by the elf Thone Silkglittered. The rules of the form are applied by composers to produce individual pieces of music which can be performed. The music is played on one to two efami and one to two thiliri. The musical voices bring melody and counterpoint. The entire performance is to be very loud. The melody and counterpoint both have short phrases throughout the form. It is performed in free rhythm. Throughout, when possible, composers and performers are to play staccato.
- Each efami always does the counterpoint melody.
- Each thiliri always does the main melody.
- The Periwinkle of Ringing has a well-defined multi-passage structure: a lengthy introduction and one to two brief passages and another one to two passages.
- The introduction should be made with feeling and accelerates as it proceeds. Each of the thiliri stays in the shrill high register. This passage is richly layered with full chords making use of the available range. The passage is performed using the cebela scale.
- Each of the first simple passages should be made with skill and is at a free tempo. Each of the thiliri ranges from the muddy middle register to the shrill high register. This passage features only melodic tones and intervals. Each passage is performed using the datome scale.
- Each of the second simple passages should feel heroic and is at a hurried pace. Each of the thiliri ranges from the watery low register to the muddy middle register. This passage is richly layered with full chords making use of the available range. Each passage is performed using the fena scale. Each passage should be composed and performed using arpeggios.
- Scales are constructed from twenty-four notes spaced evenly throughout the octave. The tonic note is fixed only at the time of performance.
- The cebela heptatonic scale is thought of as two disjoint chords spanning a tritone and a perfect fourth. These chords are named datha and aweme.
- The datha tetrachord is the 1st, the 8th, the 10th and the 13th degrees of the quartertone octave scale.
- The aweme tetrachord is the 15th, the 16th, the 24th and the 25th (completing the octave) degrees of the quartertone octave scale.
- The datome hexatonic scale is thought of as two disjoint chords spanning a tritone and a perfect fourth. These chords are named ifife and fela.
- The ifife tetrachord is the 1st, the 6th, the 12th and the 13th degrees of the quartertone octave scale.
- The fela trichord is the 15th, the 21st and the 25th (completing the octave) degrees of the quartertone octave scale.
- The fena hexatonic scale is thought of as two disjoint chords spanning a tritone and a perfect fourth. These chords are named datha and fathinu.
- The fathinu trichord is the 15th, the 16th and the 25th (completing the octave) degrees of the quartertone octave scale.
