Seeing Jersey Boys on Broadway was also a formative musical experience for her, as were Adele's 19 and Amy Winehouse's Back to Black albums, which she learned to play on piano. In high school, she performed her songs at school talent shows, was in several bands (including one with classmate Blu DeTiger), and attended shows and open mics at Lower East Side clubs with the help of a fake ID.

Teitelbaum attended Dalton School for high school; she has described her high school experience as "kind of catty, intense"{{Cite magazine |last=Cirisano |first=Tatiana |date=2018-03-16 |title=Meet BAUM, The Fiery Pop Heroine Telling Coming-Of-Age Stories For 2018 |url=https://www.billboard.com/culture/pride/baum-interview-ungodly-ep-8247583/ |access-date=2023-03-06 |magazine=Billboard |language=en-US}} and said that "music was my hideaway" during that time.

Teitelbaum was inactive for much of the year that followed, in part due to personal turmoil including her mother's death, a breakup with her boyfriend, and a split with her manager. She returned in May 2019 with the single "Fuckboy",{{Cite web |last=Blair |first=Lindsay |date=2019-05-14 |title=BAUM flips the breakup narrative on new single "Fuckboy" |url=https://earmilk.com/2019/05/14/singer-songwriter-baum-flips-the-breakup-narrative-with-new-single-fuckboy/ |access-date=2023-03-14 |website=Earmilk |language=en-US}} followed in August by "Bad Kid", whose music video was filmed in Iceland.{{Cite web |last=Beer |first=Joe |date=Aug 22, 2019 |title=BAUM shows us the deepest depths of Iceland in secluded visuals for "Bad Kid" |url=https://www.thelineofbestfit.com/new-music/discovery/baum-bad-kid |access-date=2023-03-07 |website=The Line of Best Fit |language=en-US}} "Fuckboy" was intended as the lead single of a second, longer EP, entitled Curve, to be released that fall, and a music video was filmed for a planned third single, "Girls Who Like You",{{Cite magazine |last=Cirisano |first=Tatiana |date=2019-05-08 |title=Pop Rule-Breaker BAUM Returns From 'Craziest Year' of Her Life With New Track 'F—boy' & Upcoming EP |url=https://www.billboard.com/culture/pride/baum-interview-new-single-sophomore-ep-8510543/ |access-date=2023-05-02 |magazine=Billboard |language=en-US}} although neither ultimately materialized.

Teitelbaum had long been unhappy with her pop direction as Baum, later saying "I never loved the name and I never felt fully confident in the music." In early 2020, she told producer Yves Rothman (Yves Tumor, Sunflower Bean, Girlpool), who had been working with her on Curve, that she no longer wanted to release the EP. Rothman asked to hear what else she had been working on, and upon hearing her acoustic demo of the song "Olympus", encouraged her to write more songs in that vein. Teitelbaum began writing what became her debut Blondshell album in isolation during the COVID-19 pandemic. She and her sister came up with the name Blondshell over dinner.{{Cite AV media |url=https://www.youtube.com/watch?v=iNgAlVDe-BI&ab_channel=bsidestv |title=Blondshell Says It Took Getting Older To Be Able To Write Vulnerable Songs on Debut Album |date=March 26, 2023 |last=Mar |first=Pete |type=interview |publisher=B-Sides (bsidestv) |series= |time= |access-date=March 31, 2023 |via=YouTube}}

Matt Mitchell of Paste Magazine wrote of her debut album, "No two songs sound alike, yet Blondshell is not a collage of subgenres. Instead, it’s Blondshell tinkering with her own renditions of sonic palettes previously mastered by the artists she got really stoked on during the pandemic, like Hole, Nirvana and Patti Smith. It’s indie pop fused with grunge, but it also, thoroughly, rebuffs getting lost among other ’90s alternative imitations."

Regarding her singing voice, Mitchell wrote that Teitelbaum "sings like a classically trained vocalist while injecting her charisma with the bravado of Courtney Love and the pop likability of Avril Lavigne." Her voice has been described as "a cool Gen Z deadpan that occasionally spirals up to a wistful falsetto", having "a worn-out, pessimistic tone",{{Cite web |last=Sadler |first=Armon |date=2022-06-08 |title=Blondshell Confronts An Unhealthy Relationship On New Single 'Olympus' |url=https://uproxx.com/indie/blondshell-olympus/ |access-date=2023-03-31 |website=UPROXX |language=en-US}} and varying between "a raspy chest voice and a sheer falsetto at times". Willamette Week compared her stage presence to "a stoned high schooler dancing alone to their dad’s vinyl record collection" and noted that she sang with "a gentle yet raw timbre boldly contrasted against her liberated movements across the stage".{{Cite web |last=Barr |first=Alex |date=Sep 15, 2022 |title=Blondshell Brought Her Intoxicating and Confessional Music to Doug Fir Lounge |url=https://www.wweek.com/music/concert-reviews/2022/09/15/blondshell-brought-her-intoxicating-and-confessional-music-to-the-doug-fir-lounge/ |access-date=2023-04-07 |website=Willamette Week |language=en}}

As a child, Teitelbaum's father introduced her to classic rock artists including The Beatles, The Rolling Stones (she became "obsessed" with Tattoo You after seeing them live), Bob Dylan, David Bowie, Eric Clapton, Neil Young, Cher, and Janis Joplin. Other early influences included mainstream pop artists like Avril Lavigne, Ashlee Simpson, Adele, Amy Winehouse, Madonna (one of her early songs "accidentally plagiarized" Madonna's "Hung Up"), and Teenage Dream-era Katy Perry; local NYC legends like Patti Smith and The Velvet Underground; and singer-songwriters like Tracy Chapman, Elliott Smith, Feist, and PJ Harvey. As a teenager, she discovered indie rock acts like Bon Iver, Grizzly Bear, early Tame Impala, The National, Sky Ferreira, Spoon, The Strokes, and The Killers,{{Cite web |last=Schwartz |first=Jenna |date=Jan 27, 2023 |title=Blondshell Enters Her Grunge Era |url=https://districtfray.com/articles/blondshell-grunge-era/ |access-date=2023-03-16 |website=District Fray |language=en-US}} and in college she discovered Muna.

During her BAUM iteration, Teitelbaum cited influences including Frank Ocean, Bon Iver, SZA, The 1975, Tierra Whack, The Japanese House, The Twigs, and Sharon Van Etten. She was particularly influenced in this era by Frank Ocean’s Blonde and Bon Iver’s 22, A Million. For Blondshell, she drew from artists including Hole, Kathleen Hanna, PJ Harvey, Patti Smith, Nirvana, Blur, The Replacements, Mitski, The Cure, Interpol, and the Yeah Yeah Yeahs.

Across her career, Teitelbaum has praised the music of Nilüfer Yanya, Jamila Woods, Dominic Fike, Sasami, Gus Dapperton, Caroline Polachek, Joji, Daniel Caesar, Julia Michaels, Dionne Warwick, Cardi B, and Ethel Cain. At the time of the first Blondshell album's release, she had been listening to Big Thief's Dragon New Warm Mountain I Believe in You and the music of Indigo De Souza.

Teitelbaum lives in Eastside Los Angeles with her boyfriend and a pet German Shepherd named Chinchilla. Formerly pescetarian, she has been vegan since 2020. Her amateur interest in medicine partially inspired the lyrics to "Sepsis", which uses the titular condition as a relationship metaphor.

Teitelbaum is bisexual and self-identifies as queer. She first came out in high school,{{Cite web |last=Teitelbaum |first=Sabrina |date=2017-11-07 |title=How Making Music Has Helped Me To Accept Both My Body And My Sexuality |url=https://www.huffpost.com/entry/music-can-have-the-same-affect-as-being-surrounded_b_5a00b719e4b0d467d4c22734 |access-date=2023-04-07 |website=HuffPost |language=en}} an experience that inspired the BAUM song "Hot Water" and which she wrote about for HuffPost in 2017. In interviews as BAUM, she often discussed issues such as biphobia and bisexual erasure. She has voiced mixed feelings on being labeled a queer artist, telling the Los Angeles Times: "on one hand, people need to be able to go on the internet: 'OK, I'm queer and I want to see other people who are openly singing with joy about their sexuality or about the difficulties of it.' [...] But at the same time, every artist is so much more than their sexuality."

Discussing an unreleased single with The Line of Best Fit in 2019, Teitelbaum said she was "somewhere on a spectrum in terms of masculinity and femininity. I do identify as a woman, for sure, but there's a lot of masculine energy that I have. That gets in the way sometimes, when I'm interested in someone. I'll randomly be more masculine one day, and they're like, 'what the fuck?!'" She expressed similar sentiments in a 2023 interview with Crack magazine, saying, "The binary is hard for me, because how I feel about my gender changes a lot day to day", and that exploring her shifting feelings of gender had influenced the writing of her debut album.{{Cite web |last=O'Neill |first=Lauren |date=April 13, 2023 |title=Blondshell is exactly where she needs to be |url=https://crackmagazine.net/article/profiles/blondshell/ |access-date=2023-04-29 |website=Crack}}

Teitelbaum struggled with drugs and alcohol before deciding to pursue sobriety at the end of 2019; her sobriety process influenced the first Blondshell album. She has also spoken of her struggles with anxiety, particularly social and stage anxiety. She had obsessive–compulsive disorder as a child that was treated with cognitive behavioral therapy, and she began taking Adderall in high school to help her study for exams and deal with weight gain. She had anorexia and an eating disorder from the age of ten, ultimately overcoming it in college with the help of therapy and a supportive friend group.{{Cite web |last=Villa |first=Mattia |date=Feb 13, 2018 |title=BAUM – This Body |url=https://www.wearegoingsolo.com/tracks/baum-this-body |access-date=2023-03-07 |website=Going Solo}} This, as well as an incident of catcalling she experienced at USC in 2016, inspired the BAUM song "This Body". She has voiced support for the Time's Up and MeToo movements.

In 2019, Teitelbaum said, "I really care about Judaism and I really identify with it. [...] I don't know if I personally believe in God. I've talked about it with my grandparents, who are really religious, and they say it doesn't really matter as much. I perceive Judaism as a more open-minded religion where you don't really have to follow all of the rules. It's mostly about the community, traditions, and family."
