The first single and music video from Tool’s third full-length album, Lateralus, “Schism” won the Grammy Award for Best Metal Performance for the song. “Schism” is renowned for its use of uncommon time signatures and the frequency of its meter changes – in one analysis of the song, the song alters meter 47 times. According to Wiki, the song begins with two bars of 5/4, followed by one bar of 4/4, followed by bars of alternating 5/8 and 7/8, until the first interlude, which consists of alternating bars of 6/8 and 7/8.
The following verse exhibits a similar pattern to the first, alternating bars of 5/8 and 7/8. The next section is bars of 6/4 followed by one bar of 11/8. This takes the song back into alternating 5/8 and 7/8. Another 6/8 and 7/8 section follows, and after this the song goes into repeating 7/8 bars.
The middle section is subsequently introduced, consisting of three bars of 6/8, one bar of 3/8, and one bar of 3/4 repeating several times. At one point it interrupts with two bars of 6/8 followed by a bar of 4/8, twice. A bar of 5/8 is played before the meter switches back to 6/8 for two bars and 2/4 for one bar. This repeats, setting up another section: two bars of 9/8 followed by a bar of 10/8, that pattern again, and then a single bar of 9/8 followed by alternating bars of 6/8 and 7/8. The outro has alternating bars of 5/8 and 7/8, ending with alternating 6/8, 2/8 that one could interpret as pulsing with a 4/4 feel.
So, take that.
