Check out samples from books: http: //osos.sweb.cz/preview-ukulele.pdf Czech musicologist and esthetician Otakar Hostinsky (1847-1910) published in 1892 a collection of folk songs from the Czech Renaissance. This collection contains only the melody, so I created two versions of the song for everyone. The first one is just a melody, the second one is my proposal for harmonization added by me. Have a nice time with melodies examined by time."
