Apsaras and Gandharvas

In the Vedas, the apsaras are water nymphs, often married to the gandharvas. By the time the Puranas and the two epics were composed, the apsaras and gandharvas had become performing artists to the gods; the apsaras are singers, dancers, and courtesans, while the gandharvas are musicians. They are somewhat semi-divine; we do not see them as being able to curse humans (except on one occasion) or grant them boons as gods can, but we do see them as adept in magic and knowledgeable in all of the 64 performing arts; additionally, we see many gandharvas skilled in warfare.
