'one taking bow' is the definition.
'bass viol' can be an answer for 'bow' (thesaurus). I'm not certain of the 'one taking' bit.

'victor in lab is so composed' is the wordplay.
'victor' becomes 'V' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' indicates putting letters inside.
'composed' indicates an anagram.
'lab'+'is'+'so'='labisso'
'labisso' with letters rearranged gives 'bassiol'.
'v' placed inside 'bassiol' is 'BASS VIOL'.
