The solo piece, "Spring Comes to the Grassland", is quite difficult. None of the students I have can win. I myself have been chewing it for nearly a month.
As everyone knows, "Prairie Mongolian Family" can be played. Quite simple too. In Ingemar's aria, there is a note that cannot be played on high note 1, so it can be replaced by 6. Buren Bayar's arias are completely playable.
Then there is "Ulaanbaatar's Dad". But this needs to be played with the tube tone as 1.
I haven’t discovered other songs yet
