The Toot of Winter-melons is a form of music used to commemorate important events originating in The Obsidian of Apples. The form guides musicians during improvised performances. A singer recites nonsensical words and sounds while the music is played on a arethe, three othidala and a izecenava. The musical voices are joined in melody. The entire performance should be forceful and is at a walking pace, and it is to be moderately loud. The melody has phrases of varied length throughout the form. Pitches are densely packed in clusters as music moves from chord to chord. The music repeats for as long as necessary. It is performed without preference for a scale and in the ithi rhythm. Throughout, when possible, performers are to locally improvise.
