Hearing organ finally start with melody rather low (6)
I believe the answer is:
earthy
'rather low' is the definition.
'earthy' can be an answer for 'low' (thesaurus). I'm not sure about the 'rather' bit.
'hearing organ finally start with melody' is the wordplay.
'hearing organ' becomes 'ear' (I've seen this in another clue).
'finally' indicates one should take the final letters.
The last letters of 'start with melody' are 'thy'.
'ear'+'thy'='EARTHY'
Can you help me to learn more?
(Other definitions for earthy that I've seen before include "Coarse like clay" , "Coarse like the soil" , "Crude - vulgar" , "Of the soil, lusty" , "Unenthusiastic" .)
