Ugggggh the haiku/waka debate.
Short version:
YES haiku needs a kigo (seasonal indicator word) and nature imagery.
YES other labels for THAT EXACT STRUCTURE exist.
It's not a thinker. It's equivalent to calling a petrarchan sonnet a shakespearean. Are they both valid poetry? Definitely. Are they both sonnets? Yup. Are they the same? No.
Poor senryuu. And even poorer
several other 5-7-5 syllabic forms.
crying
I think I feel strongly about this because notice who has 'decided' the form can be completely warped: a culture
completely foreign to the one the form arose in. I get the whole "adapting it so it works for us" thing, but that's why we use syllables and don't worry about character count, yeah?
It's NOT why a senryuu or other form is suddenly haiku. The blanket term that CAN be applied to all styles in that form is "waka".
/rant, with apologies lol
because I can't resist
Abused senryuu
waka's red-headed stepchild
while haiku dances
(and anyone picking on the syllables in line 1
will be forced to a basic Japanese class. Yes those u's are separate syllables
wink )
