Opening pieces (9)

I believe the answer is:

overtures

(Other definitions for overtures that I've seen before include "Orchestral introductions to an opera etc" , "Tentative suggestions to elicit reactions" , "Attempts at seduction" , "Musical introductions" , "Diplomatic advances" .)

I've seen this clue in The Wall Street Journal.
