attack音D is the 7th track on disc 1 of the "Attack on Titan" Season 2 Original Soundtrack. As with all the other pre-The Final Season OSTs, it was composed and arranged by Hiroyuki Sawano.
Title
音 ("on"), means "sound" in Japanese. The title is therefore homophonous with "Attack on D", "D" being a note.
Musical motifs
The track is split into 2 parts. The first part (0:00-2:33) is a remix of the first part of YouSeeBIGGIRL/T:T. The second part (2:35-4:40) incorporates Call your name's chorus motif at 3:44-4:22.
