"Adjutant's Call" is a bugle call indicating that the adjutant is about to form the guard, battalion, or regiment.[1]
"Assembly", "Adjutant's Call", and "First Sergeant's Call" are the three bugle calls that make up the "formation" category of bugle call.[2]

The top staff is for the bugler, while the lower staff is for the drums and the cymbals.
