Claire Rosinkranz (born January 2, 2004) is an American singer-songwriter from Southern California. She has been making music with her father since her youth.

Early life Rosinkranz grew up in Agoura and Malibu. She was homeschooled in a musical family: both of her parents and her grandmothers are involved in the music industry. Her father, Regnar Rosinkranz, is an Icelandic composer, producer, and violinist. She used to help him with ideas for songs he was writing for various television shows and commercials. He would later become her closest collaborator when she started making her own music. She has spoken about growing up with synesthesia, which is when stimulation in one physical sense causes a response from another. This caused her to envision shapes and colors in response to auditory input. Billboard News. “Claire Rosinkranz On “Chronic” Video & Making ‘My Lover’ with Synesthesia | Music You Should Know”.

Rosinkranz has been making music since she was eight years old. At the same time, she has been practicing ballet since she was three years old, which she considered her "first love". By the time she turned 11, she decided to focus more on her music career. She described herself as a perfectionist, stating that ballet's "heavily disciplined environment" had played an important role in her musical development.

Career Rosinkranz came to wide recognition when her song "Backyard Boy" went viral on the video-sharing app TikTok. The song was included on her first extended play (EP), Beverly Hills Boyfriend, which was released in 2020. A year later, Rosinkranz released her second EP, 6 of a Billion.

Artistry

Musical style and songwriting Rosinkranz's music has generally been described as indie pop, electropop, and alt-pop, with some inspirations from pop punk and funk.

Rosinkranz and her father works together to finish a song. She usually starts off by writing the whole song first, before coming into the studio and describe the song ideas to him so that he can begin working on the production. They would continue to exchange each other's ideas throughout the rest of the process. According to Rosinkranz, her father only focuses on the instrumental aspect of the music, while she would pay full attention to the lyrics. She added: "It’s nice on that level that if I’m signing about boys or whatever, he’s only looking at the music."

Influences Rosinkranz has considered her father to be the biggest influence on her artistry. She said most of her inspiration came from watching him making music. In addition, she has cited Michael Jackson, Norah Jones, Amy Whitehouse, Sufjan Stevens, Jack Johnson, The Beatles, Frank Ocean, and Daniel Caesar as her influences, alongside her home state of California. She has expressed her love for classic songwriting, particularly from Fleetwood Mac and ABBA, where "melody carries as much weight as confession". She has also taken inspiration from classical music, which has been the soundtracks to her ballet practice sessions. In addition, she is inspired by contemporary artists such as Benee and Still Woozy.

Personal life Rosinkranz lives in Agoura Hills, California as of 2021.
