Eufòria

Season 1

TV3 aired episodes, called "gala", on Fridays. The contestants were each given a solo song, as well as the background voices for two or more other participants songs. During each episode the three judges decided whether to save or send to the "danger zone (zona de perill)" each of the contestants after their performances, and at the end of the night all those nominated would be up for elimination. As well as by the judges, the contestants' harmonies were also analysed by what is called the "musical VAR", led by producer Jordi Cubino, to identify mistakes and one or more singers were nominated for elimination depending on the findings of the VAR. The coaches, on the other end, were able to "save" a participant who had been nominated for elimination by Cubino or by the judges.^[14][18] The remaining two contestants at risk of elimination were then presented to the public, who will save one via online vote, with the unsuccessful leaving the show.^[19] After the gala 6 the public was either asked to save or eliminate a contestant, depending on the episode.^[20]

On the gala 2 the "favourite" was introduced, chosen by the judges together by pressing a button (similar to the concept of the "Golden Buzzer in the Got Talent show). The favourite however could change through the night, as the judges could press the button many times and for each performer. At the end of the night, the final favourite, as well as being "safe" and automatically move to the next episode, would also be able to choose the two contestants who will be their backing singers.^[21]

During the week, the contestants would prepare and rehearse their performances with the help of various coaches: Jordi Cubino (musical director), Daniel Anglès (singing/voice), Albert Sala and Aina Casanovas (choreography) and Carol Rovira (interpretation).^[22]

During the gala 6, Marta announced that the following show would be a rematch gala, in which one of the eliminated contestants would be able to come back to the show and the public would decide by voting.^[23]

On the gala 11 (first semifinal), the contestants sang a solo song as well as a duet with a fellow contestant and their backing vocals were supported by all the eliminated participants. The most voted singer (favourite) moved directly to the final, with the last 5 singers moving to the gala 12 (second semifinal) where they sang two songs each and the two most voted by the public moved to the final, as well.

Season 2

The dynamic of the second season was similar to the first one, but the judges voted individually for each performance and, if a contestant had two or more positive votes, they were safe. For the second season, coaches Jordi Cubino (musical director), Daniel Anglès (voice) and Albert Sala and Aina Casanovas (choreography) continued to help prepare the contestants with new coach, Paula Malia, taking over as interpretation coach, replacing Carol Rovira, who became a judge. Pianist Clara Luna also coached the singers.^[10]

During the gala 3 it was announced that there would be double elimination, the first elimination would take place at the beginning and the other at the end of the episode as always. The first elimination would be put at risk the two contestants who finished in the danger zone during the second gala.^[24]

On the gala 5 the roles were reversed. The public, through voting, decided which contestants were to remain on the show and which ones went to the danger zone. The five with the most votes, would be automatically saved, the most voted would be the favourite of the night, and the remaining four contestants would go to the danger zone. On their side, the VAR was tasked with saving a contestant and the judges were the ones to choose the eliminated of the night.^[25]

During the gala 6, Marta announced that the following show would be a rematch gala, like in the previous season, and that two eliminated contestants would come back to the show.^[26]

Season 3

The first gala of the new season saw all the contestants perform in groups of four, as soloist as well as doing the background vocals for the other three. After listening to the four performances, the judges will determine who was safe and who will be sent to the "danger zone" (in this new season there was an unlimited number of contestants who could be at risk of elimination. The public will then vote for their favourites, with the last two contestant having to leave the show.

The judges for this season were Alfred Garcia, choreographer Albert Sala and Carol Rovira, returning from the previous season. The show was presented again by Marta Torné and Miki Núñez.

As in previous seasons most galas would see contestants perform their solo songs, as well as background vocals for fellow contestants. The judges would decide for each of them whether they were "the favourite", safe or in the "danger zone". Before the final votes from the public the VAR would choose if any additional contestant were to be in danger of elimination, while the coaches would be able to save their favourites. The final two contestants in danger would be voted by the public, with one staying and one leaving the show.

Galas 4 and 8 were reversed, with the public voting their favourite contestants. The six most voted would be safe (with the top one being the favourite), while the remaining ones would be at risk of elimination. The VAR would be able to save two of the bottom contestants for excelling in supporting others with background vocals.

Season 4

As during season 3, during the first gala the contestants performed in groups of four, with the judges choosing who was safe and who will be at risk of elimination. After all performances, the VAR (Cubino and Clara Luna) also sent the worst background vocalist in the "danger zone". The public was tasked with choosing their favourite, with the last two contestants leaving the show. The two additional contestants from the audition phase (Carla and Gerard) were also voted by the public, with the highest scorer, Gerard, joining the line-up for the show. During this gala it was revealed that if a contestant was episode Favourite 3 times, they will win a prize (to be revealed).

Gala 4 was reversed/backwards, with the public voting their favourite contestants as the previous year. The six most voted would be safe (with the top one being the favourite), while the remaining ones would be at risk of elimination. The VAR was able to save two of the bottom contestants for excelling in supporting others with background vocals and so were the coaches. The judges had then to decide which of the last two remaining contestants would continue and which would be eliminated from the show.
