Musically, "Singular: Act I" is a dance-pop album.
The album opens with lead single "Almost Love", which Mike Nied of Idolator described as an "edgy anthem." The song contains "intermittent whistles and drums" and is about a relationship ready to take the next step.
"Paris" is "an ode to the city of love" that reminds the singer of a Los Angeles lover while in Paris. "Hold Tight" is a "slinky and vaguely retro R&B" song that is the album's sole collaboration.
"Sue Me" is described as a "sassy kiss-off" that talks about the end of a relationship. Carpenter has also described the song as representing pure confidence.
"Prfct" is a song discussing the reality of love; the song's production puts Carpenter's vocals at the forefront. "Bad Time" is a "synth-driven" song.
Nied described "Mona Lisa" as "enticing" and containing "flirty and creative lines."
The album's closing track, "Diamonds Are Forever" sees Carpenter recognizing her worth. It contains soulful vocals from her. Julian de Valliere of The Line of Best Fit called the song a "theatrical belter."
Mike Nied of Idolator wrote that the album is an "eight-track collection is jam-packed with bop after bop."
He called the album "lush with potential hits" and "another near-perfect work from one of the industry’s brightest young stars."
Larisha Paul of EarMilk rated the album 9.0 out of ten, giving praise to Carpenter's vocals, writing that "her inarguable dynamic vocal performances that remain consistent in every track is what sets her apart from the rest."
Julian de Valliere, writing for The Line of Best Fit, rated the album 7.5 out of 10, stating that "it’s certainly no small triumph that Singular: Act I stands so firmly by itself – and its creation marks an exciting new phase of an artist properly coming into her own."
