 Petko Staynov's choral songs reveal features of the Bulgarian people's character ("A Fir Tree Is Bending"; "A Bright Sun Has Risen"; "Hey, Ivan"; "Play a Tune, Dimo"; "Oh, That Man Dimo"; "Hey, Dimo").Till the early 1930s, he followed the traditions of choral art laid by the first composers in the genre, introducing at the same time elements of his own style.With his choral ballads Staynov laid the foundation of a whole new field in Bulgarian music.
