### Clue: Composer before Liszt sounding note for Sainsbury's? (6)
### Answer: CHOPIN 
 ### Explanation: Definition: Composer
 A reverse homophone. "Chopin" **placed before**(before) "Liszt" is a **homophone of**(sounding) "shopping list"(a note of things to buy at Sainsbury's Supermarkets).
I think the homophone, with a bit of stretching, is based on the pronunciation of the answer's name in his native Polish (where the first syllable of the answer rhymes with "shore"?), or am I Baching up the wrong tree?
