Swara () or svara is an Indian classical music term that connotes simultaneously a breath, a vowel, a note, the sound of a musical note corresponding to its name, and the successive steps of the octave, or saptanka. More comprehensively, it is the ancient Indian concept of the complete dimension of musical pitch. At its most basic comparison to western music, a swara is, essentially, a "note" of a given scale.
