regular expression with brackets / comma and space

Hello,

With the help of ​@Winfried Reng , for a text selection I could use the Find/change function with “regular expression” in order to add brackets around the text selection. 

But now, inside this “regular expression” I would like to delete also the comma before this text selection.

So, I would like to select from the comma to the text selection (by example here :  , soprano) and in a single regular expression, do  two things : delete the comma and add brackets around the text selection.

How to do it ?
