I have gone through many website to learn the finger technique for harmonium. But all they mention is the technique same as keyboard.
e.g. start from c -1 d -2 e -3 f- 1 g- 2 a- 3 b 4- c-5 , 1 is thumb and so on. But I know the difference. In harmonium, they don't use pinky finger. Please if any one know the answer, please share it. It will be helpful for everyone.
