Three Tones, Not Two
Most people who encounter Vedic Sanskrit for the first time assume the pitch accent works like musical stress, one syllable louder, the rest quieter. It does not. Classical Sanskrit dropped pitch accent entirely and moved to a stress system. Vedic Sanskrit, the older layer, carries three distinct tonal positions: the udātta, the anudātta, and the svarita. The udātta is the raised syllable. The anudātta is the syllable that falls below the neutral pitch and typically precedes the udātta, functioning as its shadow. The svarita is a falling tone, a glide from high to neutral, and it almost always follows the udātta directly. What this means in practice is that pitch in a Vedic verse is never isolated to one syllable. It moves in a contour, a dip, a peak, a fall, and that contour is as much a part of the verse as the words themselves.
