The show begins with the "blind auditions", where coaches form their team of artists (eight in the first season, twelve in the second, fourth and fifth, and sixteen in the third) whom they mentor through the remainder of the season. The coaches' chairs are faced towards the audience during artists' performances; those interested in an artist press their button, which turns their chair towards the artist and illuminates the bottom of the chair to read "I want you." At the conclusion of the performance, an artist either defaults to the only coach who turned around, or selects their coach if more than one coach expresses interest.
In the "battle rounds", each coach pairs two of his or her team members to perform together, then chooses one to advance in the competition. In each season, coaches are assisted by celebrity mentors that are different each season. A new element was added in season 3; coaches were given two "steals", allowing each coach to select two individuals who were eliminated during a battle round by another coach.
The knockout rounds were also introduced in season three. A pair of artists within a team are selected to sing individual performances in succession. They are not told until a few minutes prior to their performances who their partner is. The artists get to choose their own songs in this round, although they continue to get help and advice from their respective coaches. At the conclusion of the performances, coaches would decide which one of each pair gets to advance to the next round. Just like in the battle rounds, the coaches can steal one eliminated artist from another coach starting with season 5
In the final live performance phase of the competition, artists perform in weekly shows, where public voting narrows to a final group of artists and eventually declares a winner. The coaches have the power to save one artist that had not received the public's vote that week. As of season two, these artists would give a last chance performance to win their coach's save. However, in deciding who moves on to the final four phase, the television audience and the coaches have equal say 50/50. With one team member remaining for each coach, the contestants compete against each other in the finale where the outcome is decided solely by public vote. In the first two seasons, one contestant from each team would advance to the final four. Due to the possibility of having multiple potential winners on the same team, eliminations were adjusted in season three to eliminate contestants who earned the lowest number of votes, thus not guaranteeing a coach a contestant in the (reduced) final three.
Last night, I watched the first "Battle" of The Voice of Greece. While I understand the contestants' nervousness on the stage, which is like a boxing ring, I can realise how hard it is for a coach to choose one of the two performers. Although I've never been able to develop a musical ear, I can tell who sings best to my..ear! I really loved Areti Cosmidou, Demos Beke and Mary Doutsi. In Greece , most of the contestants are prefessional artists, so it's so hard to choose. I can't wait to watch the remaining battles and I am looking forward to the first live show.
