The humor, weak and regrettable as it is, is based on the long, enforced silence, silence, silence of the family, lest anyone, hearing even a dropped shoe or a cough, realize there are people there. And then, "a drum kit"?

In case it still has not come through, the implication is that she practiced on the drum, thus giving them away in a big way, and thus it was the last diary entry.

But then (taste aside) you can't analyze or explain a joke. Well, you can, but it's like dissecting a bullfrog to find out what makes the typical bellowing call. You don't learn much, and the frog is dead.
