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. ”
