Intense musicale disrupted contemplative period (1,7,7)

I believe the answer is:

a minutes silence

'contemplative period' is the definition.
(a gesture of respect or remembrance)

'intense musicale disrupted' is the wordplay.
'disrupted' indicates anagramming the letters.
'intense'+'musicale'='intensemusicale'
'intensemusicale' with letters rearranged gives 'A MINUTES SILENCE'.
