Forbidding daughter to join quartet with no following (4)

Ross

I believe the answer is:

dour

I'm a little stuck... Click here to teach me more about this clue!

'forbidding' is the definition.
(I've seen this before)

'daughter to join quartet with no following' is the wordplay.
'daughter' becomes 'd'.
'to join quartet' becomes 'ur' (I can't justify this - if you can you should believe this answer much more).
'with' says to put letters next to each other.
'no' becomes 'o' (resembles 0 - 'no' can mean 'zero').
'following' is a charade indicator (letters next to each other).
'ur' after 'o' is 'our'.
'd'+'our'='DOUR'

Can you help me to learn more?

(Other definitions for dour that I've seen before include "Obstinate - grim" , "Stern, humourless" , "Gloomy-looking, stern" , "Grim and gloomy-looking" , "Severe, stern, gloomy" .)
