AI Overview The 1940 vocal song "June on the Isle of May" (popularized by Connee Boswell) is based on the famous Andante cantabile movement from Pyotr Ilyich Tchaikovsky's String Quartet No. 1 in D major, Op. 11.[1, 2]
Tchaikovsky composed the quartet in 1871, and the melody for the Andante cantabile was originally adapted from a Ukrainian folk song he heard a gardener sing near Kamianka. [1, 2]
