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

'big confusion' is the definition.
'maelstrom' can be an answer for 'confusion' (I've seen this before). I'm not sure about the 'big' bit.

'eminent composer accepting large maiden' is the wordplay.
'eminent composer' becomes 'maestro' (I've seen this in another clue).
'accepting' indicates putting letters inside.
'large' becomes 'L' (eg in clothes sizes).
'maiden' becomes 'm' (cricket abbreviation).
'maestro' enclosing 'l' is 'maelstro'.
'maelstro'+'m'='MAELSTROM'

'causes' is the link.

Can you help me to learn more?
