Hi Rit Until u try u will never get to know. Give a try, u never know. All the best! Regards

if a teacher has more than 4 ways to explain you one thing and knows what is passagio , stops you from pushy and throaty singing and if can relate the technique with many styles and genre then he/she can be a good choice.

As the age is tender the vocal chord is less stressed but also untrained. So in such cases emphasis should be given upon each standing notes in perfect tune so that the musical base is strong whole through...

Depends on what you are interested in learning. To play an instrument or singing. Indian classical, Carnatic, or Western. You can narrow down your search for a tutor accordingly.
