Huh! self trained? how he could self train himself with all knowledge of suur and nodes of music? Don't bent the fact just for arguing here, Amit is a trained guy, little less than Emon but far a lot more than Prashant. Remember, he helped Ankita to correct her suur and made her sing well. Ask Pooja Chatterjee, another trained one, who wished Emon and Amit to be the winner, because she believed that only trained people could perform better than untrained ones. Amit is well-educated in music unlike Prashant.
amit didn't receive any formal training, but he was into music since childhood so he knows about sur and some of the technical stuff (hence the word 'self taught'). but he's definitely not trained...read his chat transcript and interviews where he has been asked this question.
