"Oberon" opera (London, 1826) second act opens, in a magnificent salon in the palace of Haroun al Rachid, with a chorus of praise, 'Glory to the caliph', to which Weber, using bold orchestral unisons, gives an exotic flavour. After Reiza is brought in for her marriage to Babekan, to the accompaniment of woodwind, triangle and tambourine, Huon and Sherasmin rush in. (Clive Brown, 2009: 444)
