glyconics consist of a choriambic base (-uu-) preceeded by a trochee, spondee or iamb (a preceding pyrrhic is quite rare) and followed by an iamb: therefore u/- u/- - u u - u - (the / means not caesura here but, rather crudely, 'or'). The initial syllable, when a true long, can be resolved into a pyrrhic, giving uuu-uu-u-. there is no regular caesura.
enjoy. i have done very little in Glyconics, only composing them, in fact, in Latin.
