"Question!" is a song by the band System of a Down. It is the second single of their fourth album Mezmerize, which focuses on life after death. The song was first premiered by the famous Los Angeles, California radio station KROQ on May 23, 2005 and was released to alternative and rock radio stations on July 12 of the same year.
"Question!" is written in the key of E minor - a somewhat unusual key for System of a Down, which normally relies heavily on Cm, C#m, and F#m. The song uses five different time signatures (5/4, 9/8, 6/4, 3/4, and 4/4). The acoustic guitar intro and part of the verse is in 9/8 (3+2+2+2, essentially 4/4 with an extra eighth note on beat 1). The verse briefly switches to 3/4 (when Serj sings "Are you dreaming?"). The guitar motif after the acoustic intro is in 5/4. This same section appears throughout the song as well. The chorus is in 6/4. The heavy tremolo-picked section towards the end underneath the vocals is in 4/4. Serj Tankian plays acoustic guitar in the intro and deeper in the background behind lead guitarist Daron Malakian.
The song is sometimes compared to one of System of a Down's other songs "Aerials," which also deals with the nature of life in the lyrics. Both are primarily sung by Serj but seem to have Daron as back-up in the chorus. Music similarities are not as easy to spot. Aerials does not have the wide variety of time signatures that Question has (a problem that allegedly makes the song difficult for even the band to play) and the bass is used more for atmosphere in Aerials, whereas in Question it only shows up separate to the guitar for a repeated riff.
