One covered in scales swimming at cove (6)
I believe the answer is:
octave
'one covered in scales swimming at cove' is the definition.
I can't judge whether this defines the answer.
'swimming at cove' is the wordplay.
'swimming' indicates an anagram (letters swim around into a new order).
'at'+'cove'='atcove'
'atcove' is an anagram of 'OCTAVE'.
Can you help me to learn more?
(Other definitions for octave that I've seen before include "Span of eight notes" , "Set of eight musical notes" , "Interval from one C to the next C" , "At cove (anag.)" , "Musical interval of eight notes" .)
