If you wanna get better at improv go to rehearsal and practice your scenes with music underneath. I like to use soundtrack music from movies, the instrumental music. Do your scenes with that music underneath and bring that energy into your scenes. Now, when you go on stage for a show, bring a little song with you. When you step out, have a song in mind and play your scene with that character, that you’re playing with that music in your heart. And it’s gonna change the energy of your scenes, and if you can kinda have that music playing in your head as you’re doing your scene you’d be amazed at how much your energy can change and how much energy you’ll have in that scene. So bring a song with you when you go on stage.
