The "bol banao" style has a slow tempo and is concluded by a "laggi", a faster phase where the tabla player has some freedom of improvisation. Another stalwart in the genre of thumri was Naina Devi (1917–1993), who was married to a royal family but later devoted her life to the singing of the song of Tawaifs. For a member of the royal family to take such a step in those days meant fighting countless social stigmas that had enough power to totally alienate someone from the society, but she had the support of her husband. Some khyal singers took an interest in thumrī and sang it their own way, as in the case of Abdul Karim Khan, Faiyaz Khan, Bade Ghulam Ali Khan, Bhimsen Joshi, Madhav Gudi, Rajan and Sajan Mishra, Barkat Ali Khan, Jagdish Prasad and Prabha Atre. Today thumrī is sometimes sung at the end of khyal concerts as a concluding item. Besides the tabla and the tanpura, other typical instruments in thumri are sarangi, harmonium and swarmandal. Thumrī singers pay considerable attention to the lyrics, though they may be difficult to follow in the ornamented enunciation. This is especially where the focus is on love, and many lyrics deal with separation or "viraha". Krishna's "ras leela" or love play with Radha and other gopis of Vrindavan appear frequently. As an example, here are the lyrics of a thumrī composed by the medieval poet Lalan, celebrating Krishna's flute – how its tunes are driving Radha mad. Braj or Vrindavan is where Krishna is indulging in this love play; Radha is the "girl of Braj".
