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

'disturbed very' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Maybe they are linked in a way I don't understand?

'loudly elephant's head moved about' is the wordplay.
'loudly' becomes 'ff' (short for fortissimo - 'very loud' in music).
'head' says to take the initial letters.
'moved' becomes 'acted' ('act' can be a synonym of 'move').
'about' indicates putting letters inside.
The first letter of 'elephants' is 'e'.
'ff'+'e'='ffe'
'ffe' put within 'acted' is 'AFFECTED'.
