Erato was one of the nine Mousai (Muses), the goddesses of music, song and dance. In the Classical era, when the Mousai were assigned specific literary and artistic spheres, Erato was named Muse of erotic poetry and mime, and represented with a lyre. Her name means "lovely" or "beloved" from the Greek word 'eratos'.
To evoke these sensual attributes of Erato, I use the distincitvely dreamy & feminine sounding ancient Greek Hypolydian Mode - the equivalent intervals as F-F on the white notes of the piano (misnamed the 'Lydian' mode in the Middle Ages)
