A good foundation for music? (4)
I believe the answer is:
rock
This clue might be a double definition.
'a good foundation' is the first definition.
'rock' can be an answer for 'foundation' (thesaurus). I'm not sure about the 'a good' bit.
'for music?' is the second definition.
(rock is a kind of music)
Can you help me to learn more?
(Other definitions for rock that I've seen before include "to soothe baby" , "Swing" , "Lull (baby); 50s pop" , "Large stone - type of music" , "musical genre?" .)
