Tarana (Urdu: ترانہ) is a type of composition in Hindustani classical vocal music in which certain words and syllables (e.g. "odani", "todani", "tadeem" and "yalali") based on Persian and Arabic phonemes are used in a medium-paced (madhyalaya) or fast (drut laya) rendition. It was invented by Amir Khusro (1253-1325 CE), and is similar to the Qalbana form of Sufi poetry. In modern times, the tarana is most commonly associated with the singer Amir Khan, who researched its origins and the syllables used, and helped popularize it.
