Question

Which phrase indicates a change in mood within the excerpt?

“struck a few impressive chords”
“smiling shamefacedly at his own credulity”
“a fine crash from the piano”
“interrupted by a shuddering cry”

Answer 1

1- struck a few impressive cords

Answer 2

It would be “interrupted by a shuddering cry” because presumably, the mood of the excerpt beforehand did not express a somber or nervous feeling. To be interrupted by a cry means that the current mood has been changed
