Based out of Noida, Anurag Dixit’s Musicology covers it all – from drum lessons to music production to singing classes. They have more than enough teachers, and cover all aspects of music. They also offer certificate courses for vocal music. They really help boost your confidence, and help improve your singing skills over a reasonable duration of time (if you’re willing to put in that sort of effort and dedication). They’re definitely one of the best in the city that we’ve heard of so far.
