She released with her debut single "Paruparo" (Butterfly), and earned her a nomination for Best New Artist at the 2020 MYX Music Awards.
In 2018, she broke into the music scene with "Tila Tila" (Like a Star). She evolved into a songwriter unafraid to showcase "unguarded moments of vulnerability with captivating rawness" through tracks such as "Ayaw" (Don't Want), "Paruparo", and "Hiwaga" (Mystery).

The EP was produced by Brian Lotho. The recording of Gabay was initially scheduled for March 2020 but was delayed for three years due to the COVID-19 pandemic and personal challenges. The tracks "Kung Nag-aatubili", "Pakay" (Purpose), and "3:15 (featuring kiyo)" were written by herself years ago during a dark period in her life, while the title track "Gabay" and "Lipad" (Fly) were composed during the pandemic.

Artistry Songwriting style and themes Hartha's music blends elements of folk and pop, often characterized by primarily acoustic instrumentation. Her debut EP Gabay, showcases this fusion, chronicling her pains, traumas, and musings as a young woman.
She is known for her delicate vocals and lyrical complexity, often exploring themes of abuse, existentialism, and self-forgiveness. Her songs serve as a medium for expressing deeply personal experiences, many of which she admits she has yet to fully heal from. In an interview with Bandwagon, she shared, "There are songs I wrote about experiences I honestly haven’t completely healed from yet and struggle to talk about, but the fact that I’m not just doing all this for myself empowers me and makes me want to fight more."
Influences Syd Hartha cites Lorde and Jhené Aiko as major influences on her music. Her music is rooted in the acoustic genre, influenced by her mother’s fondness for listening to Paramore during her childhood. She developed a passion for playing instruments, eventually learning to play the guitar and write songs. She has cited Original Pinoy Music (OPM) bands such as Spongecola and Parokya ni Edgar.
