Pallavi
In Carnatic music, a Pallavi is a thematic line, usually consisting of one line or stanza of poetry (or solfege syllables), that is sung repeatedly with variations during a performance. It forms the core of the Tanam-Pallavi improvisation. The Pallavi is often the most complex and intellectually demanding part of a Carnatic music concert.
The word "Pallavi" itself is derived from the Sanskrit roots "Pada" (word, foot) and "Lava" (to seize, to grip), implying a line that is firmly grasped or held.
The Pallavi generally establishes the raga (melodic framework) and tala (rhythmic cycle) for the improvisation that follows. It serves as a constant reference point to which the musicians return after exploring various melodic and rhythmic possibilities.
The structure of a Tanam-Pallavi typically involves the Pallavi being sung in different speeds (tempos), in different ragas (a concept known as Ragamalika), and with intricate rhythmic calculations and combinations. Skilled musicians demonstrate their mastery by creating complex variations while adhering to the rhythmic framework established by the Pallavi.
