Rāgas that have four swaras are called "" (सुरतर) rāgas; those with five swaras are called "audava" (औडव) rāgas; those with six, "shaadava" (षाडव); and with seven, "sampurna" (संपूर्ण, Sanskrit for 'complete'). The number of swaras may differ in the ascending and descending like rāga Bhimpalasi which has five notes in the ascending and seven notes in descending or Khamaj with six notes in the ascending and seven in the descending. Rāgas differ in their ascending or descending movements. Those that do not follow the strict ascending or descending order of swaras are called "vakra" (वक्र) ('crooked') rāgas.
