The name of the sonnet is, well, 'Sonnet' because it is about the experience of writing a sonnet. But that is like naming your dog "Dog."
How about 'Meta Sonnet'? 'Sonnet to the Second Power'? 'Shall I Compare Thee to The Words of the Bard'? I will consider any and all suggestions.
For practice, in iambic I will write;
although ‘tis foreign writing lines this long.
I do this, for I cannot sleep tonight.
These words perchance can soothe me, as a song.
Ah yes, the rhythm is a melody,
a cadence that caresses as it flows.
For in these lines there can be no spondee,
and my beloved trochees dare not show.
But music of the muse is often wild,
intense, unmetered; minor chords abound.
Then how to find true voice in form so mild,
and honor craft and meaning in the sound?
But hark! The tune emerged here from my head,
so off I go to pentametric bed.
