如歌的行板其實是柴可夫斯基String Quartet No. 1 in D major 一個樂章. It was the first of Pyotr Ilyich Tchaikovsky's three string quartets, and his Opus 11. The quartet has 4 movements:
The melancholic Andante cantabile movement has become famous, and was founded on a folk-song the composer heard whistled by a house painter. When the quartet was performed at a tribute concert to Leo Tolstoy, the author was said to have been brought to tears by this movement.
這個四人演奏也不錯
