I remember during the early EMET episodes, Twinkle used to sing at her normal scale and sing very well but Vishwas used to find it difficult to adjust and loose sur.After a few episodes Vishwas started singing at his normal scale and Twinle started adjusting but the outcome for the jodi was excellent.
Vishwas in is interview to tellychakkar gave credit to Twinle for doing lot of hard work on him.
That girl is overall very talented and will go a long way.
