What is "valaji"

Valaji or Valachi is a rāgam in Carnatic music (musical scale of South Indian classical music). It is a pentatonic scale (audava or owdava rāgam, which means "of 5"). It is a janya rāgam (derived scale), as it does not have all the seven swaras (musical notes). The equivalent of Valaji in Hindustani music is Kalāvati.
