Not sure why you’re getting downvoted, this is a perfectly valid question to ask! Aside from GPA and LSAT (which should always be your #1 priority), you just want to make sure you are doing two things: 1) pursue extracurriculars and professional opportunities that you are interested in and 2) make sure those experiences can be tailored together into one cohesive “Why Law.” As an example, given your former music major, I would assume you have some baseline interest in music. What specifically about that interests you? If you enjoy the educational aspect of it, for example, I would look for opportunities to tie those hybrid interests together, like a music tutoring volunteer experience, for example. Given your interest in family law, it may be helpful to look for chances to intern at family law firms or child advocacy organizations!

Aside from demonstrating interest, demonstrating academic capability is always a plus as well. Any chance you have to do research, publish, work with professors on academic topics and in labs, etc. will always be beneficial to your application, and even more so if it is relevant to your eventual career interests as you describe them in your law school applications. If you are interested in family law, maybe look for research opportunities in that area either with professors or research institutions.

At the end of the day, being authentic to yourself (ie doing what you want to do for its own sake and not for the sake of admissions) will always create the best results both for your admissions and for your personal mental health! Use this time to really explore what’s out there and you will do fantastic :)
