The Vedic meters are Gayatri, Ushnik, Anushtup, Brihati, Pankti, Trishtup, Jagati, Aticchanda, Atyashti, Atijagati and Ativirat.
The Gayatri meter has twenty-four syllables, the Ushnik twenty-eight, the Anushtup thirty-two, and so on, each meter having four more syllables than the previous one. Vedic sound is called brihati, or most expansive, and thus it is not possible for ordinary living entities to understand all the technical details in this matter.
