Hi, is there any app that helps to know how the sur is on bansuri. Initially, I used to practice sa from tanpura and now Shruti box. I want to know if there is an app to know whether my sur is correctly going or not. I am using tuner app but it might not be the best for such aspect.

So its been around 1.5 months I have been learning flute. I have radhe flutes C natural PVC. but i was thinking to get a bamboo base flute. yesterday randomly met a flute seller asked if he had G base. He had a G middle. he said he gets base if someone asks. I tried g middle i never heard the g middle so dont really know how was it. He said it comes from barieley, UP. Made from some shimla side ki bamboo. Niether I had the money at that time nor i wanted g middle. he was looking very weak. He said "bhaiya boni nhi hui subah se"it was around 7pm. it was clear from his eyes. I want to help him. Thinking to get a C sharp bamboo. But don't really know how to check quality and stuff. Since it was just 250. I think can take a chance.

tell me if you have any from these flute seller.
