A man was in a bar, crying after he found that his wife had been cheating on him. He starts talking to another man who is sitting right next to him. As the man was talking to the other man, the man gets a realization that the person that he is talking to is the person that his wife is secretly seeing. Enraged, the man takes a broken beer bottle and clobbers the other man to death.
Percy Grainger did an amazing job conveying this. As in the beginning, it is a sad tune. However, with the Trumpet Solo, it gives a sense of eeriness that the man felt when he found out. Towards the end with the crescendo, it is the anger that the man holds towards the other man.
