The music and background score is composed by female composer Revaa. Mughizh marks Revaa's entry into Tamil cinema. She has earlier worked on Malayalam film Mangalyam Thanthunaena, Marathi film College Diary besides composing for digital media, pilot films and more than 200 ad jingles. The entire Background score of Mughizh has a subtlety throughout that reflects the fragile storyline. The organic acoustic treatment was deliberately done to make the mood more personal and heart warming. The songs were mastered and mixed by Balu Thankachan at 20db Sound Studios.
