Smooth limb before tattoo oddly removed (6)
I believe the answer is:
legato
'smooth' is the definition.
(musical term)
'limb before tattoo oddly removed' is the wordplay.
'limb' becomes 'leg' (leg is a kind of limb).
'before' says to put letters next to each other.
'oddly removed' indicates alternate letters (letters in odd-numbered positions removed).
The alternate letters of 'tattoo' are 'ato'.
'leg'+'ato'='LEGATO'
(Other definitions for legato that I've seen before include "Smoothly flowing in style" , "(Music) without breaks between notes" , "Smoothly (musical)" , "Smoothly flowing (music)" , "Smooth, flowing (mus.)" .)
