The instruments play between a allegro and moderato tempo which emphasize the frustration and desperation in Sun-mi's lyrics towards her ex lover. Aside from this, the rhythms of the music create an intense energy that matches the theme of the track. Furthermore, in "Gashina," Sun-mi’s vocal delivery shifts seamlessly from soft, almost vulnerable tones to commanding, powerful moments, which showcase her heartbreak audibly and helps listeners tune into the theme of the song. 

In "Siren," the song’s lyrics address holding onto a toxic relationship to the mythical allure of a siren. Along with the lyrics, the main aspect of this song are the siren sound effects which alerts the listeners to the dangers that come with gravitating towards unhealthy love. Furthermore, the song combines consonance and dissonance by using these high pitches alarms and sirens combined with layered synths and bass. In doing so, this element mirrors the theme of attraction veiling reality. Similarily, this song has conjuct melodies mixed with slight disjunct bits. As a result, this mixture brings a cool tension to the song that blends well with SUNMI's unique vocals. 

"Noir" is more of a moody, edgy song by Sun-mi. She uses similar instruments to previous songs but the bass is prominent in this track. Along with the instruments, sound effects of glass breaking are added which aids in Sun-mi's storytelling of bringing attention to the dangers of social media and what people do for likes and views. Although the music is very complex, when added with SUNMI's deep vocals, the music blends in smoothly and slightly fades into the background. As a result of this consonance, SUNMI's message is the focus of "Noir" with the music giving this track a memorable melody. 

In "Tail," SUNMI switches it up by making this track more seductive and sensuous with a flirty, darker concept. This song relies on synths, bass, and guitar riffs, and rhythmic percussion to portray this new edgy side of SUNMI. With its dramatic shifts in tempo, “Tail” showcases Sun-mi's desire for a passionate, spontaneous love. Specifically, she does this by layering these instruments at an allegro tempo before swiftly removing all of them leaving the sultry synths to play at an adagio tempo for just a quick moment. Then, just as fast as they disappeared, all the instruments play once more. Although its sudden, this change keeps the track from being repetitive and rather pulls listeners in to Sun-mi's desires portrayed in "Tail." 

This song is a dreamier, retro song from SUNMI. Her ethereal vocals combined with the band ( consisting of drums, triangles, synths, marimba/xylophone) creates a weightlessness that aligns with the metaphor of being on the moon, where gravity is reduced to one-sixth.  The melodies create consonance in "1/6" and are built on smooth rhythms, that in turn create a sense of calm throughout the song. We can also see this in the tempo of the track, there is no dramatic changes, instead maintaining a consistent, calming groove. As a result, SUNMI makes us reflect on the balance between carrying emotional burdens and letting them go, embracing the complexity of seeking lightness without losing one’s sense of self.
