I visited this museum once when I went to mysore.its the cool place in mysore.it has nicely sculped instruments which you cannot see anywhere for some moments it will feel like your eyes is fooled.Many different bands all over the world plays the musical instruments.it is not a good developed or fancy place but nicely maintained old building with good staff.here you can spend two hours at the most.the ticket fare is nominal.this is the first museum of wax.inside a room you can many sculptures made up of wax.
They also has beautiful design candles which there sells at a reasonable price.I think this place is worthy of visiting and I recommend everyone to visit if you go to mysore.
