Did you get it right?
Compare panel A with panel B from left to right. The five changes are intentionally small.

The Answer
The correct answer is: Five changes: baton direction, music-sheet count, bunting stripe color, clock time, and trumpet-valve count..
Here is why
- The conductor’s baton points in the opposite direction.
- One music stand has a different number of visible sheets.
- A bunting stripe changes color.
- The clock hands show a different time.
- The trumpet has a different number of visible valves.
Why people miss it
The crowd, flowers, and band uniforms repeat across both panels and pull attention away from the small edits.
