The mark is a sound. The mark consists of a string instruments processed with FX in the key of G Major crescendo, of which the notes are G2, A2, D3, G3, and D4, played for one second. The chord is followed by two melodic sub kicks, of which the first note is G1, played for one second, and the second note is B1, played for one second, ending with a chime run though a convolution reverb with the sound of the reverberation reversed followed by the final chime playing D5 and A5 in unison for five seconds.
