what key is mirrors by justin timberlake in
Mirrors (Justin Timberlake song) "Mirrors" is a mid-tempo[4] progressive pop[5] and R&B[6] ballad[4] with an approximate length of eight minutes and five seconds. It is composed in the key of E♭ major, set in common time and has a moderately slow groove of 77 beats per minute.[7] Timberlake's vocals span from the low note of E♭3 to the high note of C5 (sheet music commonly prints the notes of a melody an octave higher to keep it within the staff).[7] The original mix has an instrumentation of emo power ballad guitar strobes, hand-claps, orchestral flares, electro blips and chipmunk synth chirps accompanied with "vocoder-squawk backing vocals",[8] and the orchestra has a noticeable much-lower volume than the percussion and electric guitars.[9]
