The trochaic inversion

[wasellajam]

But truth is, it's hard to say any one word at the same amplitude as any other. If we're going to designate
every word as either stressed or unstressed, there's a lot of rounding up or down that needs to be done.
I guess we could be more accurate by assigning an amplitude level from zero to ten.

I agree that there are varying degrees of accents. Consider this line:

A ball will bounce, but less, and less.

Though it reads as obvious iambs, the accent 'amplitude' drops off between the 'B' words, and the 'L' words. I find it interesting that it accurately describes a bouncing ball, as the bouncing amplitudes diminish.

I discovered this example in another discussion regarding accents/meters, and found it fascinating.

Great example, that's finding the poetry in meter, so effective. When I try to purposely use trochaic inversions the line never sounds right to me, this is something to consider.
