In this system, notes on the page are assigned to groups of long and short values based on their context . " De mensurabili musica " describes six rhythmic modes, corresponding to poetic feet : long-short ( trochee ), short-long ( dactyl ), short-short-long ( anapest ), long-long ( spondee ), and short-short ( pyrrhic ).
22.
At the " low end " are forms such as the "'limerick "', which follows a metrical pattern of two lines of anapestic trimeter ( three anapests per line ), followed by two lines of anapestic dimeter ( two anapests per line ), followed by one line of anapestic trimeter . ( The beginning of the metrical foot does not have to coincide with the beginning of the line . ) Any poem following this metrical pattern would generally be considered a limerick, however most also follow an AABBA rhyme scheme.
