If I Can Stop One Heart From Breaking for Drum Corps 

Drum Corps arrangement of If I Can Stop One Heart From Breaking from Honkai Star Rail. I transposed it to Bb so a corp could play it. Also, the Trumpet and flugelhorn can play the same part.
Because of the key change, the transposition at measure 24 goes to E major, then to Eb at 25 to move it back into Bb. It sounded weird going from Ab to Bb without any transition so hopefully this works fine.
