SIRENS (1996) for flute & alto flute (or two C flutes) by Roger C. Vogel was composed for flutist Ronald Waln. As the title suggests, the work is intended to be suggestive of the irresistible music produced the mythological Sirens, partly bird and partly human creatures. The flute is especially suited for this purpose since the Sirens were often depicted playing wind instruments as well as singing. The opening measures of the work feature in a prominent way the descending augmented second and semitones that were characteristic of the Ancient Greek chromatic scale.
