when the chord changes to F Major, the bass remains the same, resulting in a strong feeling of tension and dissonance, as the relationship between the F chord and the B note is a tritone, the most unstable interval in music. In the last verse (The Judge's verdict), a distorted electric guitar enters, playing a leitmotif from the album, a melody first heard in "Another Brick in the Wall" (and most recently reprised in the outro to "Waiting for the Worms"). Concerts and versions In the Berlin performance, before The Wall crumbles, it briefly "becomes" the Berlin Wall, building up graffiti like the actual wall until it is pulled down. In the gatefold art, when the judge looks over the crowd, it seems that the "marching hammers" of fame are all lined up in his possession. In the film version, the animation from the stage show is used, but certain shots (including the Schoolmaster turning into a hammer) were stretched from their original full-frame image to a 2.39:1 aspect ratio. The rest of the animation that was featured reused the original cels though expanded the backgrounds to fill the cinematic image. Waters used the film's anamorphic version for his 2010–13 tour of The Wall. In 2009, pianist Andreas Behrendt released an instrumental version of the song. The British rock group Church of the Cosmic Skull covered the song on the 2018 tribute album The Wall [Redux].
