The Butterfly of Intricacy

The Butterfly of Intricacy is a form of music used for entertainment originating in The Dungeon of Verses. The form guides musicians during improvised performances. The music is played on a ostob. The entire performance should be fiery, and it is to become louder and louder. The melody has short phrases throughout the form. Only one pitch is ever played at a time. It is performed using the nuklat scale and in free rhythm.

• The ostob always does the main melody.
• The Butterfly of Intricacy has a well-defined multi-passage structure: an introduction and a brief passage and another one to two passages.
• The introduction is at a free tempo.
• The first simple passage is very slow.
• Each of the second simple passages is fast. Each passage should be performed using rapid runs and frequent modulation.
• Scales are conceived of as two chords built using a division of the perfect fourth interval into eight notes. The tonic note is a fixed tone passed from teacher to student. After a scale is constructed, notes are named according to degree. The names are uto (spoken ut), nol (no), dab (da), agun (ag), ung (ung), stotho (sto) and bor (bo).
• As always, the nuklat heptatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named lubu and ngub.
• The lubu tetrachord is the 1st, the 3rd, the 4th and the 8th degrees of the fundamental perfect fourth division.
• The ngub tetrachord is the 1st, the 3rd, the 7th and the 8th degrees of the fundamental perfect fourth division.
