No charisma needed to play these? (10)

I believe the answer is:

harmonicas

'these?' is the definition.
The definition suggests an adverb but the answer is not.

'no charisma needed to play' is the wordplay.
'needed' is a charade indicator (letters next to each other).
'to play' indicates anagramming the letters.
'no'+'charisma'='nocharisma'
'nocharisma' is an anagram of 'HARMONICAS'.

(Another definition for harmonicas that I've seen is " Instruments - maraschino (anag)".)

I've seen this clue in The Times.
