The Periwinkle of Hemp-Seeds

The Periwinkle of Hemp-seeds is a form of music used for entertainment originating in The Wavy Giant-Grouper. The rules of the form are applied by composers to produce individual pieces of music which can be performed. A chanter recites nonsensical words and sounds. The melody has phrases of varied length throughout the form. Only one pitch is ever played at a time. It is performed in the wori rhythm. Throughout, when possible, composers and performers are to play rapid runs and play staccato.

• The chanter always does the main melody and should be bright. The voice ranges from the low register to the middle register.
• The Periwinkle of Hemp-seeds has the following structure: a theme and a series of variations on the theme possibly all repeated.
• The theme accelerates as it proceeds, and it is to start loud then be immediately soft. The passage is performed using the ithi scale.
• The series of variations is at a free tempo, and it is to fade into silence. The passage is performed using the seyawi scale.
• 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 viceva (spoken vi), moro (mo), ebalo (eb), wonethu (wo), bolo (bo), ocaquica (oc) and slothepanine (slo).
• As always, the ithi heptatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named oyifolewe and ifiyo.
• The oyifolewe tetrachord is the 1st, the 4th, the 7th and the 8th degrees of the fundamental perfect fourth division.
• The ifiyo tetrachord is the 1st, the 3rd, the 5th and the 8th degrees of the fundamental perfect fourth division.
• As always, the seyawi hexatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named ucame and izeli.
• The ucame tetrachord is the 1st, the 5th, the 6th and the 8th degrees of the fundamental perfect fourth division.
• The izeli trichord is the 1st, the 5th and the 8th degrees of the fundamental perfect fourth division.
• The wori rhythm is made from two patterns: the teze (considered the primary) and the oquino. The patterns are to be played over the same period of time, concluding together regardless of beat number.
• The teze rhythm is a single line with eight beats divided into four bars in a 2-2-2-2 pattern. The beats are named oyathu (spoken oy) and slutha (slu). The beat is stressed as follows:
• | - x`| x x | x x | x x |
• where ` marks a beat as early, x is a beat, - is silent and | indicates a bar.
• The oquino rhythm is a single line with four beats divided into two bars in a 2-2 pattern. The beats are named kecace (spoken ke) and the (the). The beat is stressed as follows:
• | x - | - x |
• where x is a beat, - is silent and | indicates a bar.
