Vedic chanting is the recitation from memory of the Vedas, Hinduism's oldest scriptures, in Sanskrit. For some three thousand years chanters have kept the exact words, pitch accents and pronunciation by also reciting the words in set patterns that make any slip easy to spot.
The oldest of the four Vedas, the Rigveda, was composed roughly between 1500 and 1000 BC and was passed on by memory for many centuries before anyone wrote it down; pupils still learn it by ear from a teacher. Besides reciting a text straight through, chanters learn it in fixed rearrangements called pathas. In a simple one, the words are chanted in overlapping pairs (1-2, 2-3, 3-4); in the most complex, ghana, they run forwards and backwards in long interlocking loops. Because every version must match the others, a slip in one shows up at once. UNESCO proclaimed the tradition of Vedic chanting a Masterpiece of the Oral and Intangible Heritage of Humanity in 2003.
