Born and raised in Omaha, Nebraska, Kate Hamann started studying the trumpet at 10 years old. As her passion for performing grew, she attended the Interlochen Arts Academy at 16 years old. There she studied classical and jazz trumpet with Ken Larson and Bill Sears (respectively), graduating with the class of 2018. Kate then attended the Frost School of Music at the University of Miami, and studied with legendary artists Brian Lynch, Etienne Charles, and John Daversa. It was also during college Kate discovered her love of singing, and decided to incorporate her voice into her musicianship.

As a 2022 graduate of the Frost School of Music, Kate is now a freelance artist based in Miami. She has played with many distinguished artists including Jennifer Hudson, Dafnis Prieto, Maria Schneider, Brian Lynch, John Daversa, Dave Liebman, and Terri Lyne Carrington. In 2020 she was named a semifinalist of the National Trumpet Competition (jazz division). In 2020 she self-released her first EP, When I Grow Up. In 2022, one of the compositions from her EP, "Her Colors", was selected for the JEN Young Composer Showcase at the JEN conference in Dallas, TX.

Kate's music is inspired by artists such as Camila Meza, Braxton Cook, Brian Blade, and Gretchen Parlato. By using her trumpet and voice in a way that can make them seem like one continuous instrument, she aims to bridge the gap between instrumental and vocal music. In doing so, she brings a fresh and inviting sound to jazz. She aspires to create music that is enjoyable by all types of listeners regardless of "genre". As an educator, Kate currently serves as adjunct professor of trumpet at Miami Arts Charter School and teaching artist at the Community Arts Program in Miami, FL.
