The book Notes on Prosody by polyglot author Vladimir Nabokov compares differences in iambic verse in the English and Russian languages, and highlights the effect of relative word length in the two languages on rhythm. Nabokov also proposes an approach for scanning patterns of accent which interact with syllabic stress in iambic verse. Originally Appendix 2 to his Commentary accompanying his translation of Aleksandr Pushkin's Eugene Onegin, Notes on Prosody was released separately in book form. Notes on Prosody and Nabokov's translation of Eugene Onegin sparked considerable academic debate. Bely's influence Nabokov in large part follows the system described by Andrei Bely in his paper "Description of the Russian iambic tetrameter" ("Опыт характеристики русского четырехстопного ямба") published in the collection of essays Symbolism (Символизм) (Moscow, 1910). Terminology The word stress is reserved for the underlying unvarying pattern of the iambic rhythm, and the word accent is used to describe where the accent falls in speaking a line. He introduces the notion of a scud, which he defines to be an unaccented stress (page 9). He uses U shaped symbol and / to illustrate. He describes a number of types of scuds (page 18): tilted scud — an inversion, where the accent falls on the first syllable of an iambic foot, of which there are various types: split tilt — an accented monosyllable followed by an unaccented one short tilt — an accented monosyllable followed by an unaccented first syllable of a polysyllabic word duplex tilt — a disyllabic word where the accent falls on the first syllable in ordinary speech long tilt — the first two syllables of a trisyllabic word, where the first syllable is accented in ordinary speech reverse tilt — an unaccented stress followed by an accented depression (non-stress) (thereby falling across two iambic feet) the main variety of which is the: split reverse tilt — two monosyllables the first not accented and the second accented (i.e. the fairly common xx// ending to line) duplex reverse tilt — a disyllabic word accented on the second syllable 'against the grain' of stress-unstress; Nabokov somewhat misinterprets Robert Bridges discussion of "Recession of accent" in his book Milton's Prosody, claiming that Bridges 'designates' the duplex reverse tilt as 'recession of accent', whereas Bridges starts from the phenomenon of 'recession of accent' as analysed by Alexander Schmidt and proceeds to analyse possible occurrences of it in Milton's verse.
