Gloomy and stressed note (8)
I believe the answer is:
downbeat
'gloomy' is the definition.
(I've seen this in another clue)
'and stressed note' is the wordplay.
I cannot quite see how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is located in the answer.
'note' could be 'do' (musical note, as in do-re-mi) and 'do' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for downbeat that I've seen before include "Pessimistic; understated" , "Depressed - relaxed" , "Gloomy; laid-back" , "Miserable; relaxed" , "Conductor is likely to make this movement" .)
