Q. What is the correct ending (singular or plural) to this sentence? This moving, musical journey inspires “drummers” of all ages to follow the beat in their heart. Is it hearts? Is it beats and hearts? Is it just beat and heart? This is driving me insane! Please help!
A. Since the drummers don’t share a single heart, you’re definitely going to need a plural of that. For “beat,” the question is whether you want it to mean literal beats of the heart, or a more abstract beating akin to music. (E.g., we say “follow the beat” when teaching music, not “follow the beats.”) You could choose either. They have slightly different meanings, but I think you probably need the singular.
