A "krithi" is a type of classical composition in Carnatic music, primarily used in vocal performances. These pieces are often devotional in nature, expressing themes of love, devotion, and spirituality. Krithis are typically structured in three sections: pallavi, anupallavi, and charanam, allowing for improvisation and elaboration by the performer. Composed by renowned musicians like Thyagaraja, Dikshitar, and Shyama Sastri, krithis are integral to the repertoire of Carnatic music. They are usually set to specific ragas (melodic frameworks) and talas (rhythmic cycles), showcasing the intricate relationship between melody and rhythm in this traditional art form.
