East German Oscar frames a Turner, that's continuously repeated (8)
I believe the answer is:
ostinato
'that's continuously repeated' is the definition.
I can't tell whether this definition defines the answer.
'east german oscar frames a turner' is the wordplay.
'east german' becomes 'ost' ('east' in German).
'oscar' becomes 'O' (phonetic alphabet: alpha, bravo, charlie etc.).
'frames' indicates putting letters inside (outside letters frame the inside letters).
'a turner' becomes 'tina' (Tina Turner, famous singer).
'ost'+'o'='osto'
'osto' placed around 'tina' is 'OSTINATO'.
Can you help me to learn more?
(Other definitions for ostinato that I've seen before include "Noted phrase often repeated" , "melodic phrase" , "figure seen in bars" , "Continually repeated phrase (music)" , "Ground" .)
