Instrument posh Richard played (11)

I believe the answer is:

harpsichord

'instrument' is the definition.
(harpsichord is a kind of instrument)

'posh richard played' is the wordplay.
'played' is an anagram indicator.
'posh'+'richard'='poshrichard'
'poshrichard' with letters rearranged gives 'HARPSICHORD'.

(Another definition for harpsichord that I've seen is " Early keyboard instrument".)

I've seen this clue in The Telegraph.
