Newspaper being able to capture one good indication of the pulse (4,9)
I believe the answer is:
time signature
'indication of the pulse' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'newspaper being able to capture one good' is the wordplay.
I cannot quite understand how this works, but
'newspaper' could be 'times' (The Times is an example) and 'times' is found in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
The remaining letters 'nature' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for time signature that I've seen before include "Mark before the first bar?" , "Musical notation - intimate urges (anag)" , "Indicator on score of musical rhythm" , "guide for players" , "Indication of musical rhythm" .)
