Svara or swara is a Sanskrit word that connotes simultaneously a breath, a vowel, the sound of a musical note corresponding to its name, and the successive steps of the octave or saptak. More comprehensively, it is the ancient Indian concept about the complete dimension of musical pitch. Most of the time a svara is identified as both musical note and tone, but a tone is a precise substitute for sur, related to tunefulness. Traditionally, Indians have just seven svaras/notes with short names, e.g. saa, re/ri, ga, ma, pa, dha, ni which Indian musicians collectively designate as saptak or saptaka. It is one of the reasons why svara is considered a symbolic expression for the number seven.
