The Autumnal Bulb
The Autumnal Bulb is a devotional form of music directed toward the worship of The Beans of Autumn originally devised by the dwarf Atis Carriedbridged. The form guides musicians during improvised performances. The music is played on one to two sodor and a uspax. The music is melody and rhythm without harmony. The entire performance is very fast. The melody has short phrases throughout the form. Only one pitch is ever played at a time. It is performed using the sasne scale and in the osmze rhythm.
- Each sodor always does the main melody and should be fiery.
- The uspax always provides the rhythm and should be passionate.
- The Autumnal Bulb has a simple structure: a passage.
- The simple passage is to be moderately loud. The passage should be performed using trills.
- Scales are conceived of as two chords built using a division of the perfect fourth interval into eight notes. The tonic note is fixed only at the time of performance.
- As always, the sasne hexatonic scale is thought of as two disjoint chords drawn from the fundamental division of the perfect fourth. These chords are named ogo and ngub.
- The ogo tetrachord is the 1st, the 4th, the 5th and the 8th degrees of the fundamental perfect fourth division.
- The ngub trichord is the 1st, the 7th and the 8th degrees of the fundamental perfect fourth division.
- The osmze rhythm is made from three patterns: the kabu, the tuxxu and the usmdas. The patterns are to be played over the same period of time, concluding together regardless of beat number.
- The kabu rhythm is a single line with five beats. The beats are named ron (spoken ro), zudol (zu), zaxo (za), ospo (os) and strog (stro). The beat is stressed as follows:
- | - x x - - |
- where x is a beat, - is silent and | indicates a bar.
- The tuxxu rhythm is a single line with twenty-one beats divided into three bars in a 7-7-7 pattern. The beat is stressed as follows:
- | - - - x'x - x | x - x x x - - | x x - x x x - |
- where ' marks a beat as late, x is a beat, - is silent and | indicates a bar.
- The usmdas rhythm is a single line with thirty-two beats divided into four bars in a 8-8-8-8 pattern. The beats are named uto (spoken ut), nol (no), dab (da), agun (ag), ung (ung), stotho (sto), bor (bo) and osm (osm). The beat is stressed as follows:
- | - - x - - x x x`| x - - - - - x x | x - x`x'- - - x'| x - x x'x - x'- |
- where ` marks a beat as early, ' marks a beat as late, x is a beat, - is silent and | indicates a bar.
