OBS. 1.—­The word prosody, (from the Greek—­[Greek:  pros], to, and [Greek:  dae], song,) is, with regard to its derivation, exactly equivalent to accent, or the Latin accentus, which is formed from ad, to, and cantus, song:  both terms, perhaps, originally signifying a singing with, or sounding to, some instrument or voice.  PROSODIA, as a Latin word, is defined by Littleton, “Pars Grammaticae quae docet accentus, h. e. rationem atollendi et depremendi syllabas, tum quantitatem carundem.”  And in English, “The art of ACCENTING, or the rule of pronouncing syllables truly, LONG or SHORT.”—­Litt.  Dict., 4to.  This is a little varied by Ainsworth thus:  “The rule of ACCENTING, or pronouncing syllables truly, whether LONG or SHORT.”—­Ains.  Dict., 4to.  Accent, in English, belongs as much to prose as to poetry; but some deny that in Latin it belongs to either.  There is also much difficulty about the import of the word; since some prosodists identify accent with tone; some take it for the inflections of voice; some call it the pitch of vocal sounds; and some, like the authors just cited, seem to confound it with quantity,—­“LONG or SHORT.” [459]

OBS. 2.—­“Prosody,” says a late writer, “strictly denotes only that musical tone or melody which accompanies speech.  But the usage of modern grammarians justifies an extremely general application of the term.”—­Frost’s Practical Grammar, p. 160.  This remark is a note upon the following definition:  “PROSODY is that part of grammar which treats of the structure of Poetical Composition.”—­Ibid. Agreeably to this definition, Frost’s Prosody, with all the generality the author claims for it, embraces only a brief account of Versification, with a few remarks on “Poetical License.”  Of Pronunciation and the Figures of Speech, he takes no notice; and Punctuation, which some place with Orthography, and others distinguish as one of the chief parts of grammar, he exhibits as a portion of Syntax.  Not more comprehensive is this part of grammar, as exhibited in the works of several other authors; but, by Lindley Murray, R. C. Smith, and some others, both Punctuation and Pronunciation are placed here; though no mention is made of the former in their subdivision of Prosody, which, they not very aptly say, “consists of two parts, Pronunciation and Versification.”  Dr. Bullions, no less deficient in method, begins with saying, “PROSODY consists of two parts; Elocution and Versification;” (Principles of E. Gram., p. 163;) and then absurdly proceeds to treat of it under the following six principal heads:  viz., Elocution, Versification, Figures of Speech, Poetic License, Hints for Correct and Elegant Writing, and Composition.
