Just As Well

[ICSoria]

...Sid, I'd call the whole thing iambic tetrameter, with the first line starting on a headless iamb (acephalous). In the last line, "musical" pronounced clearly does produce a triple foot, though I would scan it as:

of MUS/ ical-CABS/ and MASQ/ uerADE
iamb/ anapaest/ iamb/ iamb

However, when it's read aloud, the last two syllables of "musical" are pretty much elided so they just slip in and it really doesn't affect the iambic tetrameter... unless you're really anal... which only a few of us are.
...don't let ANYONE tell you that scansion is an exact science...

Leanne,
I thank you for that succinct lesson. I indeed understand this is not an exact science but sincerely appreciate someone with a better perspective offering a more exact analysis of meter in a particular line.
