16 Songs: 20 Juries

Sixteen songs will participate in the first Semi-Final, and professional juries in each of the participating countries, as well as in Spain, Austria, France and Australia, voted on yesterday's dress rehearsal. They account for 50% of the overall total.

Each jury member ranks all the songs in the show by judging each song, each jury member should focus on the vocal capability of the artists, the performance on stage, the composition and originality of the song, and the overall impression by the act.

The EBU's televoting partner Digame will merge the points given by the jury and the televoters tonight per individual country. If there is a tie between two or more songs between jury votes and televotes, then the song gaining the most televotes will be ranked higher.

The live show of the first Semi-Final of the Eurovision Song Contest 2015 will take place on Tuesday 19th of May at 21:00 CET and will broadcast live on Eurovision.tv or on our YouTube.
