The pyrrhic/spondee substitution

[milo]

I saw the red kite flying high in a black sky

So you're saying an occassional line like that might fly? If a poem was full of that it seems I wouldn't notice any set meter at all.

First, you definitely would notice this if it was held continuously because it is almost impossible, I made double subs here because I was practicing my spondees too much, lets see what it looks like and what we can do to fix it:

i SAW the RED KITE flying HIGH ina a BLACK SKY

iamb iamb troche iamb pyrrhic Spondee

So I did get the spondee sub and this would actually be completely acceptable in a line of iambic HEXAMETER but that wasn't the challenge so lets fix it:

One, there are too many feet
Two, there is the trochaic sub that was not part of the challenge

I saw the sparrow fly in a black sky

iSAW theSPAR rowFLY ina BLACK SKY

iamb iamb iamb pyrrhic spondee

Good catch
