The String-bean of Humming is a devotional form of music originating in The Freeman of Supplying. The rules of the form are applied by composers to produce individual pieces of music which can be performed. The music is played on a vus. The entire performance should be melancholic. Only one pitch is ever played at a time. It is performed without preference for a scale and in free rhythm. Throughout, when possible, composers and performers are to syncopate and alternate tension and repose.
