taking the lead
Trumpets can be used to play recognizeable melodies, and thus may serve as leading or solo instruments. Hence, "playing the trumpet" could be a euphemism for "taking the lead", for instance, in a group working on a project, as opposed to a lecture hall, where the lecturer has the superior role towards all attendees.
