Quiet a long time after championship and start of book (5,5)
I believe the answer is:
title pages
'start of book' is the definition.
'quiet a long time after championship' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'a long time' becomes 'ages' (I've seen this before).
'after' means one lot of letters go next to another.
'championship' becomes 'title' ('title' can be a synonym of 'championship').
'p'+'ages'='pages'
'pages' after 'title' is 'TITLE PAGES'.
'and' is the link.
(Another definition for title pages that I've seen is " Front part of book".)
