The Boll of Wreathing

The Boll of Wreathing is a devotional form of music originally devised by the mer Zelu Giant-Grouperfrightful. The form guides musicians during improvised performances. The music is played on a apapa, a osani and three riraya. The musical voices cover melody, harmony and rhythm. The melody has short phrases throughout the form. It is performed using the mila scale and in free rhythm.

• The apapa always should be fiery.
• The osani always should evoke tears and uses grace notes.
• Each riraya always should be fiery and uses grace notes.
• The Boll of Wreathing has a well-defined multi-passage structure: one to two passages and an additional brief passage, a bridge-passage and a brief finale.
• Each of the first simple passages is voiced by the melody of the osani and the harmony of the apapa. Each passage is at a free tempo, and it is to become softer and softer. The apapa ranges from the slicing middle register to the floating high register. This passage is richly layered with full chords making use of the available range.
• The second simple passage is voiced by the melody of the osani, the harmony of the apapa and the rhythm of the riraya. The passage is at a hurried pace, and it is to be loud. The apapa covers its entire range from the buzzy low register to the floating high register. This passage is richly layered with full chords making use of the available range.
• The bridge-passage is voiced by the melody of the apapa, the melody of the riraya and the rhythm of the osani. The passage is slow, and it is to be very loud. The apapa ranges from the slicing middle register to the floating high register. Only one pitch is ever played at a time in this passage.
• The finale is voiced by the melody of the apapa and the melody of the osani. The passage accelerates as it proceeds, and it is to become softer and softer. The apapa stays in the slicing middle register. Chords are packed close together in dense clusters in this passage.
• Scales are constructed from twelve notes spaced evenly throughout the octave. The tonic note is a fixed tone passed from teacher to student.
• The mila pentatonic scale is thought of as two disjoint chords spanning two perfect fourths. These chords are named ipila and izeli.
• The ipila trichord is the 1st, the 3rd and the 6th degrees of the semitone octave scale.
• The izeli trichord is the 8th, the 9th and the 13th (completing the octave) degrees of the semitone octave scale.
