I found about Sangeet Sadhana 4 months back when I was looking for a good Hindustani classical coach for my 7 year old daughter. I have seen a lot of improvement in my daughter's voice and rhythm in this short span. Sangeet Sadhana is about serious learning and the teachers out there give utmost attention to the progress of each kid.
Recently they organised a musical concert Udaan where all the kids performed. Some of the musicals played on this evening really gave goosebumps since we do not get to hear these classical melodies live these days.
In all I think Sangeet Sadhana is a perfect choice for Hindustani classical music in Bangalore for kids and adults.
