Jazz pianist reversed interminable key change (6)
I believe the answer is:
mutate
'change' is the definition.
(mutating is a kind of changing)
'jazz pianist reversed interminable key' is the wordplay.
'jazz pianist' becomes 'tatum' (I've seen this in another clue).
'reversed' shows that the letters should be reversed in order.
'interminable key' becomes 'e' (musical key. I am not sure about the 'interminable' bit.).
'tatum' in reverse letter order is 'mutat'.
'mutat'+'e'='MUTATE'
Can you help me to learn more?
(Other definitions for mutate that I've seen before include "Change in basic nature" , "Undergo change to another form" , "(In genetics) change" , "Undergo genetic change" , "Gradually change form" .)
