The legend of the dombra
talented
giants
broke
There is an old legend about the
who lived in the Altay mountains. And there were two brothers who were very friendly and helped each other all the time. The younger brother had a dombra. He loved the music very much. He played the dombra all the time and everywhere. The elder brother was proud of his
brother. Everybody knew about the younger brother.
Then the elder brother wanted to be famous too. He decided to build the bridge over the fast and cold river. He began to gather stones for his bridge. The elder brother asked his brother for help. But the youngest brother didn’t listen to him and continued playing the dombra. Then he became very angry with him. He took his brother’s dombra and
it against the rock. The beautiful instrument was broken, and the music stopped. But there was a stamp on the stone left after the dombra hit the rock. Many years passed. People found this stamp and made a new dombra. And the music that hadn’t played for such a long time was heard once more.
