(Sanskrit: conversation), in the art music of India and Pakistan, improvised melody structured to reveal a raga and occurring principally in the introductory section of a performance. There the alapa is performed without rhythmic accompaniment and is free and rhapsodic in character. With only a drone (sustained-tone) accompaniment, the performer of the alapa gradually introduces the essential notes and melodic turns of the raga to be performed. Only when the soloist is satisfied that he has set forth the full range of melodic possibilities of the raga and has established its unique mood and personality will he proceed, without interruption, to the metrically organized section of the piece. If a drummer is present, as is usual in formal concert, his first beats serve as a signal to the listener that the alapa is concluded.
