Is there evidence in Imam Malik's Sharh Muwatta (Commentary on the Muwatta) regarding the prohibition of music, and if so, where can it be found?

The use of musical instruments is forbidden by agreement of the four schools of thought. Al-Baji stated in Al-Muntaqa that if a wedding contains impermissible amusement, such as the oud or tunbur, then one is not obligated to attend. As for the round drum (duff) or large drum (kubar), it is permissible at weddings for women, but not for men, and without instrumental playing or singing, except for rajaz poetry recited in a plain manner. If a walimah (wedding banquet) contains forbidden amusement, the obligation to attend it is nullified. Whoever attends and finds such amusement should return, and this is the opinion of a group of jurists. Imam Malik disliked singing and selling female singing slaves.
