'bloomer made by tiny' is the definition.
I can't tell whether this definition defines the answer.

'child inspiring key chamber work' is the wordplay.
'child' becomes 'mite' (mite can informally mean a small child).
'inspiring' indicates putting letters inside.
'key' becomes 'g' (musical key).
'chamber work' becomes 'nonet' (I've seen this in another clue).
'g'+'nonet'='gnonet'
'mite' going around 'gnonet' is 'MIGNONETTE'.

Can you help me to learn more?
