The festival Melodies of the Sea and Sun [Melodije morja in sonca] was launched in 1978 in the coastal town of Piran. Set up as a competition of newly composed pop music, it was similar to the Slovenska popevka Festival and when the latter was put to a stop, it overtook its role in regularly providing popular hit songs and putting quite a few of them into the evergreens repository. The songs were - and still are - lyrically and musically focused on the themes of summer, the sea and other related topics.
The festival has been almost continuously running since the start and has been for most of the years broadcast live on Televizija Slovenija. While the first edition was held in Piran, later it was more or less staged at the Portorož Auditorium, which is currently co-organising the festival together with Radio-Television Slovenia (RTV Slovenia).
