The Bloom of Rhythms is a form of music used for entertainment originally devised by the goblin Muspoxostrog Gratuitousspun. The form guides musicians during improvised performances. The music is played on one to five urogugsmanga, a san and a laxsat. The musical voices bring melody, counterpoint and rhythm. The entire performance should be energetic and is fast. The melody has mid-length phrases, while the counterpoint has short phrases 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 free rhythm. Throughout, when possible, performers are to use grace notes.
