The sheet music collection "Ukrainian song" for accordion is the creative work of the author Kateryna Pylypenko. The collection consists of 32 songs, which include both Ukrainian folk melodies and popular songs of Ukraine. Kateryna Pylypenko is also the illustrator of the sheet music collection. She independently drew the illustrations that accompany the musical notes in the collection. This adds aesthetic and artistic value to the sheet music. The author has developed an arrangement both for a ready-made left-hand accordion keyboard and for a ready-to-select keyboard. This makes the collection accessible to both beginners and experienced musicians. "Ukrainian Song" is a valuable resource for accordionists who are interested in learning traditional and modern Ukrainian music. The collection not only provides notes for the performance of songs, but also offers original interpretations and arrangements, which add a special color and variability to the performance of Ukrainian music on the accordion.
