Some years ago, while watching Adalat, I was struck by the interesting way in which the song Jaa jaa re jaa saajna was composed (by Madan Mohan). It begins as a plaintive, melancholic song, the singer (Nargis, lip-syncing to Lata Mangeshkar’s voice) filling her song with the emotion she feels at being betrayed. Then, just as one had settled into thinking that this was a particular type of song, the tone of the song changed. The tempo increased, and though the lyrics still conveyed the same emotion, the singer (Asha Bhonsle) made them so teasing and flirtatious that their import changed. Two songs, one slow and anguished, one fast and vibrant, but woven together into one song.
What an impressive performance, I thought: and it occurred to me that there were other songs, too, of this type, where a composer and a lyricist create two songs but weave them together. Note that I’m not talking of the back-to-back songs, like Kya se kya ho gaya/Mose chhal kiye jaaye. I mean songs where the two styles of the song alternate. Also note that I regard two tempos of the same tune as two different styles.
