There are four musical pitches or notes in the melody of this recitation. The melody is notated using three marks—an underline, an accent, or a double accent—to indicate when changes in pitch take place.
A vowel with no marks above or below is sung on a central note.
A vowel with a horizontal line beneath is sung on a note lower than the central one (for example, kavim).
A vowel with a single accent above is sung on a note higher than the central one (for example, namáste).
A vowel with a double accent above it is held for two beats and sung on a higher note on the second beat (for example, namő ).
A good way to learn the melody and pronunciation for reciting Shri Rudram is by listening to someone who knows it, or to a recording, while reading the words. Begin by reciting mentally as you listen, then gradually practice reciting aloud.
