Syllable length

Raymond MacDonald Alden,  English Verse: Specimens Illustrating its Principles and History

“ These illustrations, then, may serve to show that while we do not coördinate our consonantal syllable-lengths as absolute "shorts" and "longs," we perceive certain degrees of length, and find these playing a part in our verse.
So much for intrinsic quantity as found in English syllables. But there is much more to be said for syllables made long or short at the will of the speaker, under certain conditions. If we address a friend in surprise, saying, "Why, John!" we not only throw a heavy stress on both the words, but also perceptibly prolong them.

Portrait of Edgar Allan Poe Edgar Allan Poe,  The Rationale of Verse

“ But if we dwell on both equally, and with a tripping voice, saying to ourselves here are two short syllables, the query might well be asked of us–"in relation to what are they short?" Shortness is but the negation of length. To say, then, that two syllables, placed independently of any other syllable, are short, is merely to say that they have no positive length, or enunciation–in other words, that they are no syllables–that they do not exist at all. ”

Clement A. Harris,  How to Write Music: Musical Orthography

“ A syllable will often require more space than a note, consequently in very simple music the words require more space than the music. In florid compositions a syllable, on the other hand, is often sung, not to several notes merely, but to several measures, and the music requires much more space than the words. In the former case the author has found it a good plan to write the words first, or at least a measure or two of them, as a guide in estimating their average length. ”
