Bansuri (Bamboo Flute) is an Ancient Instrument that will require 30 to 45 mins of daily Practice.). The more you practice the faster you’ll learn the art. If you skip a day of practice, its result will reflect the next day and you personally would feel the difference. So always be in touch with this instrument. Don’t think that if you play for 5 days you can let go for 2 days and then again you’ll start practising. It will do you no good. Your learning time for the instrument will increase. 
                    In the starting days, you’ll also feel some dizziness if you practice for long periods. But it’s okay. Relax and once the dizziness gets over, start again. This happens because your body is not used to it and you don’t have the stamina. But don’t worry over time stamina will slowly increase with practice.
