Devotional recitals performed on sopana (steps in front of the sanctum sanctorum) came to be known as Sopana Sangeetham. It is a very ancient form of Kerala
's indigenous music. The musical notes of Sopana Sangeetham are of an ascending or descending nature. The music is accompanied by edakka
. The song varies according to the time of performance and the deity. Musicians stand on the left side of the sopana and the singing stops once the temple opens.
