 A knock-out system will be introduced whereby each of the eight artists are split into four groups of two, and the voters can vote for their favourite in each pair.The four winners go through to a second round, where they will be paired off again, with the winners of each pairing going through to the final.The first semifinal of Melodifestivalen 2007 took place in Kinnarps Arena in Jönköping on 3 February 2007.
