Experimenting with an Improvised Sonnet

dare I attempt this unprepared
to bring metered form to this verse
speak out each line mouth ev’ry word
without my notebook’s coarse rehearse
I risk the taste of failure’s breath
should inspiration run and hide
each line unfinished, the poet’s death
a verse rejected cast aside
but at this point that’s passed the mark
my spirits start to find their way
and each further phrase defeats the dark
I may yet see the light of day
so safely I’ve the form traveresed
to land upon this final verse
