'moment of vertigo' is the definition.

'trumpeter's cardinal' is the wordplay.
'trumpeter's' becomes 'Dizzy's' (Dizzy Gillespie, US jazz musician, p9p7-p99l).
'cardinal' becomes 'pell' (I can't justify this - if you can you should give a lot more credence to this answer).
'dizzys'+'pell'='DIZZY SPELL'
