In the black Poem workbox appears whatever text you select from the List of Poems, which is searchable by alphabetical order, by difficulty level, and by verse type.  As you move the cursor just above a line of verse in the workbox, the space above each syllable glows.  Click once in this space to mark a syllable as stressed, twice as slack, a third time to clear the space.  Once you’ve marked each syllable, click the first icon to the right (arrows).  A green, red, or yellow light will let you know you’ve scanned the line correctly, incorrectly, or somehow problematically. Moving the cursor directly across the words highlights syllables one by one.  By clicking within the text you can divide the stresses and slacks into the feet that make up a line of metered English verse: iamb, trochee, anapest, dactyl, spondee, pyrrhic.  Clicking the middle icon to your right (footprints) will show how you did with this part of the exercise.  Once you’ve gotten the green light here, click on the last  icon (triangle) to open a menu from which to identify the meter of the scanned line. In order to focus on one aspect of scansion at a time, use the Stress and Foot division checkboxes at the bottom of the workbox to toggle your markings off and on.  A third checkbox toggles occurrences of a Caesura, or strong mid-line pause, within the entire text.  (You can’t alter these caesura marks; they’re free gifts to your curiosity.) Click the Rhyme tab in the lower left corner of the workbox, and a column of highlighted squares will open.  Locate your cursor in the square beside each line of verse, type in the lowercase letter corresponding to that verse’s place in the rhyme scheme, and when you’ve marked the whole poem click the bottom checkbox to see how you did.  Next to the green stress check by certain lines a lightbulb icon will turn on.  Clicking this will open a note that discusses oddities or beauties of the line in question.  Once your scansion of the full text is correct, and only then, a Syncopation checkbox appears next to the others down below.  Clicking it brings out in new color the poem’s rhythmic discrepancies. Three tabs above the workbox are always available for navigation.  A hot-link cross-referenced Glossary provides brief definitions of prosodic terms.  The Help tab will let you consult the introductory Overview or shorter sections like this one, which are keyed to the subtitles at the top of this page.  Click the Poem tab to return to the workbox. Where 4B4V provides further resources on a given poem, you will also find a Resources tab beside the others.  Click there to find, e.g., a select bibliography of scholarship on the poem, or an audio clip that you may open to hear it read aloud.
