Eighteen songs will participate in the second Semi-Final, and professional juries in each of the participating countries, as well as in Germany, Italy and United Kingdom, will be voting on tonight's show. They will account for 50% of the overall total.
Each jury will be comprised of five members, (including a chairperson) who will be the same jurors who will also be voting in the Final. They will monitored by an independent notary in each country. The jury consists of a variety of members in terms of age, gender, and background. They are all citizens of the country they are representing.
The juries vote tonight, so that the EBU has a valid voting result before tomorrow's live show. Should any unexpected problems occur in the televoting, the jury votes can be used as back-ups. This setup also allows the EBU and PwC, who carefully monitor the voting, to assure the validity of the jury voting before the live show. In case of apparent irregularities, a national jury vote may be discarded.
None of the jury members are connected with any of the participating songs or artists, in order that they can vote independently. All jury members have made signed declarations stating that they will vote independently.
You can find out who is in each national jury below.
Each jury member will rank all the songs in the show by judging each song, each jury member will 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.
You can see a further explanation of the voting in the short video below.
