When we study Shakespeare on the page, for academic purposes, we may require all kinds of help. Generally, we read him in modern spelling and with modern punctuation, and with notes. But any poetry that is performed - from song lyric to tragic speech - must make its point, as it were, without reference back.

I don't see that a single line can constitute a stanza, although it can constitute a whole poem.

Poetry carries its history within it, and it is oral in origin. Its transmission was oral.

Writing for the page is only one form of writing for the eye. Wherever solemn inscriptions are put up in public places, there is a sense that the site and the occasion demand a form of writing which goes beyond plain informative prose. Each word is so valued that the letters forming it are seen as objects of solemn beauty.

For poets today or in any age, the choice is not between freedom on the one hand and abstruse French forms on the other. The choice is between the nullity and vanity of our first efforts, and the developing of a sense of idiom, form, structure, metre, rhythm, line - all the fundamental characteristics of this verbal art.

An aria in an opera - Handel's 'Ombra mai fu,' for example - gets along with an incredibly small number of words and ideas and a large amount of variation and repetition. That's the beauty of it. It's not taxing to the listener's intelligence because if you haven't heard it the first time round, it'll come around again.

The basic rhymes in English are masculine, which is to say that the last syllable of the line is stressed: "lane" rhymes with "pain", but it also rhymes with "urbane" since the last syllable of "urbane" is stressed. "Lane" does not rhyme with "methane".
