The technique

That's just the first part...

Now? Break up ever letter of every word from every line.

Mark it. Mark it. Mark it. Really. Mark the f**K out of it! (pardon my french)

Pour example - 

Mark your text for how many beats each letter gets. 

Put one line underneath a letter if it gets one drum beat, and two lines if it makes a sustainable sound. For my case, because of my computer - the letters that are underlined have one drum beat while the larger letters in bold make a sustainable sound.

Gallop apace, you fiery-footed steeds, Toward Phoebus' lodging.

Once you've done that, work on the y-buzz! It's that meditation sound in yoga that makes your whole body vibrate. Pronounce the biggest letters in italic with the same manner.

Gallop apace, you fiery-footed steeds, Toward Phoebus' lodging.

Then, put it all together: 

Gallop apace, you fiery-footed steeds, Toward Phoebus' lodging.

Now go back to the original line:

Gallop apace, you fiery-footed steeds, Toward Phoebus' lodging.

...and voila,

2 ½ lines down...29 more to go!!!
