The Azure Glimmer is a form of music used during marches and military engagements originally devised by the human Emoth Whisperedfog. 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 umon and a sina. The musical voices are joined in melody. The entire performance should evoke tears and accelerates as it proceeds. The melody has short phrases throughout the form. Only one pitch is ever played at a time. It is performed without preference for a scale and in free rhythm.
