The sistrum was occasionally revived in nineteenth century Western orchestral music, appearing most prominently in Act 1 of the opera "Les Troyens" (1856–1858) by the French composer Hector Berlioz. Nowadays, however, it is replaced by its close modern equivalent, the tambourine. The effect produced by the sistrum in music – when shaken in short, sharp, rhythmic pulses – is to arouse movement and activity. The rhythmical shaking of the sistrum, like the tambourine, is associated with religious or ecstatic events, whether shaken as a sacred rattle in the worship of Hathor of ancient Egypt, or, in the strident jangling of the tambourine in modern-day Evangelicalism, in Romani song and dance, on stage at a rock concert, or to heighten a large-scale orchestral tutti.
