I found many very nice apps for android using keywords "music notes" and "teach perfect pitch". Very useful applications, indeed. However, they all use "A B C" system which is not used in our region; we use only "do re mi" system. I have learned in music school for 2 years and I even do not know which letter corresponds to each note. I was not able to find any app for "do re mi" system and currently I am not able to find how this system is called and which is the right keyword.
My educated friends, can you please help me? With keyword.
