Double double toil and trouble....okay you Shakespeare buffs - help me out here

[NKF]

The witches' spell
Eye of newt etc. Is the rhyme scheme trochaic or something else?
Any help out there on the bard wise MN?

1 WITCH. Thrice the brinded cat hath mew'd.
2 WITCH. Thrice and once, the hedge-pig whin'd.
3 WITCH. Harpier cries:?'tis time! 'tis time!
1 WITCH. Round about the caldron go;
In the poison'd entrails throw.?
Toad, that under cold stone,
Days and nights has thirty-one;
Swelter'd venom sleeping got,
Boil thou first i' the charmed pot!
ALL. Double, double toil and trouble;
Fire burn, and caldron bubble.
2 WITCH. Fillet of a fenny snake,
In the caldron boil and bake;
Eye of newt, and toe of frog,
Wool of bat, and tongue of dog,
Adder's fork, and blind-worm's sting,
Lizard's leg, and owlet's wing,?
For a charm of powerful trouble,
Like a hell-broth boil and bubble.
ALL. Double, double toil and trouble;
Fire burn, and caldron bubble.
3 WITCH. Scale of dragon; tooth of wolf;
Witches' mummy; maw and gulf
Of the ravin'd salt-sea shark;
Root of hemlock digg'd i the dark;
Liver of blaspheming Jew;
Gall of goat, and slips of yew
Sliver'd in the moon's eclipse;
Nose of Turk, and Tartar's lips;
Finger of birth-strangled babe
Ditch-deliver'd by a drab,?
Make the gruel thick and slab:
Add thereto a tiger's chaudron,
For the ingrediants of our caldron.
ALL. Double, double toil and trouble;
Fire burn, and caldron bubble.
2 WITCH. Cool it with a baboon's blood,
Then the charm is firm and good.

Oh go on, someone, please.

Do you mean a "rhyme" scheme? - or meter, ie rhythm?

Trochaic is the opposite of iambic: iambic goes de-DUM de-DUM de-DUM, trochaic goes DUM-de DUM-de DUM-de ("London Bridge is falling down" is trochaic - note extra stressed half-foot at the end - witches' spell does same thing.)

Anyway, trochaic is accurate description of scansion for witches' spell. It's same as for "Fear no more the heat o'the sun ..."

Sorry, I meant metre.

So it's stress on eye and then on new and then on toe and then a half trochaic foot with the stress on frog?

Thanks Bink.

Absolutely. Imagine them taking a breath, or doing a weird sinister flick of finger, at the end of each line to fill in the little gap (you can sense it) left to complete the last foot.

While I'm about it, the first & third lines below are complete trochaic tetrameter; the second & fourth have that fabulous little meaningful gap:

Loosened from the minor's tether
Free to mortgage or to sell
Wild as wind, and light as feather
Bid the slaves of thrift farewell

Bink, you're good. You're very good. Thank you.
