Foundation degree in education and music (7)
I believe the answer is:
bedrock
'foundation' is the definition.
(I have seen 'Solid foundation' mean 'bedrock' so perhaps 'foundation' could also mean 'bedrock')
'degree in education and music' is the wordplay.
'degree in education' becomes 'bed' (I can't explain this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'music' becomes 'rock' (rock music).
'bed'+'rock'='BEDROCK'
Can you help me to learn more?
(Other definitions for bedrock that I've seen before include "Basis" , "Fundamental principles" , "Solid foundation" , "Fundamental principle" .)
