Cooper Heise is an audio engineer and session bass player with a deep love for the process of making music sound perfect. Whether it’s mixing a track recorded in a bedroom or dialing in the final touches on a full ensemble production, my focus is always the same: helping artists create something that’s clean, dynamic, and true to who they are.
My approach is rooted in both technical and musical skillsets I’ve spent years developing. I use that blend to deliver mixes that feel alive, emotionally resonant, and sonically clear. No shortcuts, no templates, just honest, handcrafted sound.
Brought up in Kansas City, I was constantly surrounded by a thriving music scene, a scene that crafted my musical knowledge. I moved to Nashville to be part of a city where collaboration and creativity coexist constantly. Every project I take on is a personalized connection to the artist.
