Violin musical styles may be translated as "filling" (or "stuffing" in the culinary sense), since multiple instruments "fill out" the sound. The Indian violin, while essentially the same instrument as that used in Western music, is different in some senses. The instrument is tuned so that the IV and III strings (G and D on a western-tuned violin) and the II and I (A and E) strings are sa-pa (do-sol) pairs and sound the same but are offset by an octave, resembling common "scordatura" or fiddle cross-tunings such as CGCG or AEAE. The tonic sa (do) is not fixed, but variably tuned to
Basic physics of the violin pitch, which may be described in terms of frequency. The playing tension of a violin string ranges from about to . The length of the string also influences its pitch, and is the basis for how a violin is played. Violinists "stop" a string with a left-hand fingertip, shortening its playing length. Most often the string is stopped against the violin's fingerboard, but in some cases fingertip contact alone is enough to stop the string at the desired sounding length. Stopping the string at a shorter length has the effect of raising its pitch. String material affects the quality of
