Shakespeare character, explorer carrying black instrument (5,2,5)
I believe the answer is:
viola da gamba
'instrument' is the definition.
(viola da gamba is a kind of instrument)
'shakespeare character explorer carrying black' is the wordplay.
I cannot really understand how this works, but
'character' could be 'viola' (I have seen 'Shakespearean character' mean 'viola' so perhaps 'character' could also mean 'viola') and 'viola' is located in the answer.
'black' could be 'b' (as in pencil classifications) and 'b' is present in the answer.
The remaining letters 'dagama' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for viola da gamba that I've seen before include "Such as was, eg, Shanghai" , "Forerunner of cello" .)
