I agree.
There are many ways to generate emotion, or to try to...
I don't think that a sense of calm is incompatible with resources that focus on musicality and phrasing.
This is very evident in vocal music, even in the great pop performers.
A very simple and effective example from Beethoven: there is a first bar, which is isolated (by the quarter note rest), there is a second bar that is identical and works the same way. And then, the two simply appear without the pause.
Wow, a super-effective way to generate tension, dynamism, and phrasing without changing the basics.
Charles Ives' The Unanswered Question is a fantastic example. The harmony couldn't be more static, but the melody (more or less dense in texture depending on the moment) does not conform to the divisions of the harmony. In fact, the tempo of the harmonic part is fixed (Largo) and that of the other parts changes.
