a moment of peace during a chaotic summer
a sense of shared responsibility and shared guilt
all of the above*** my answer

Answer 1

All of the Above. You're Right. Correct, I mean.

Answer 2

The Musical Theory basically describes two things: on the one hand, how one or another piece of music is composed; and on the other hand, how this or that attribute of a composition affects the listener, the way in which he perceives or experiences the piece.

In this last theoretical activity, in the description of how the attributes of a composition affect the listener's experience, countless verbal terms or expressions of a metaphorical nature are sown.

The answer is: None of the above.
