Keyboard instrument Melba and co recollected (7)

I believe the answer is:

cembalo

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

'keyboard instrument' is the definition.
(I know this)

'melba and co recollected' is the wordplay.
'and' is a charade indicator (letters next to each other).
'recollected' is an anagram indicator (letters recollected and rearranged).
'melba'+'co'='melbaco'
'melbaco' with letters rearranged gives 'CEMBALO'.

Can you help me to learn more?

(Other definitions for cembalo that I've seen before include "Old instrument" , "It is instrumental" , "Dulcimer" , "Harpsichord" .)

I've seen this clue in The Times.
