The Sensual Butterfly is a form of music used during marches and military engagements originally devised by the human Atho Dippedslipped. The form guides musicians during improvised performances. The music is played on a ime, a kise and a ini. The musical voices cover melody, harmony and rhythm. The melody has phrases of varied length throughout the form. Never more than an interval sounds at once. It is performed without preference for a scale and in free rhythm. Throughout, when possible, performers are to modulate frequently.
