The caja, a drum similar to a tambora, is one of the three main or traditional instruments of the Vallenato music. Caja, the slang word adopted to nickname this drum, means "box" in Spanish. There is a Caribbean drum called caja, used in the music of Colombia. African slaves brought by the Spanish colonizers came along with tamboras to what is now northeastern Colombia derived from the Congolese makuta drum. Tamboras were first adopted by the Cumbia musical genre and introduced to Vallenato music. With the advancement of technology new make and models developed the traditional drum into an instrument similar in make to a conga. Traditional: Elliptic cylinder made out of wood and a cow skin stretched over the top wider opening and tighten with rustic ropes 30 cm of height. Modern Version: similar in made to a congas drum but shorter in height. Made out of the same wood base but no ropes are used to stretch and hold the skin, instead a metal frame bolted to the wooden base is used to hold the animal skin or X-ray photo made skin.

Vallenato has four different rhythms to which the caja adapts to mark the base key: Rubbing and strucking with hand palms. Son Paseo Merengue Puya

Influenced by electropop musical styles, Queen of the Clouds is predominantly a concept album which divides the record into three sections: "The Sex", "The Love" and "The Pain". Similar to the theme of poisoned relationships explored on Lo's debut extended play, Truth Serum, the album centers on a breakup and provides a complete narration of her romantic struggles, she described her music as "like a therapist" where Lo could sing about things she would not feel comfortable speaking about.

Queen of the Clouds blends multiple styles of music into a "monogenre" sound, containing heavy influences of EDM, hip hop, dance-pop, new wave, R&B, combining them into a "seamless compendium". The first section, "The Sex", opens the record with four songs about the "lecherous and reckless" beginning of a relationship, are composed in a "infectious and tongue-in-cheek stampede of uptempo pop." Album opener, "My Gun", has been described as an urban-influenced pop song textured with elements of dancehall. It begins with a "mournful"-sounding choir before building to an upbeat pop groove. Lo's vocals are seductive, before gliding into her higher range; the track explores the "flirty" stage before delving into more sexual themes, found on "Talking Body", has been compared to the works of Rihanna. Lyrically, Lo compares her lover to "her gun" and sings of feeling a release of pleasure: "Boy, if you're gonna shoot me down/Do it gently"; the next track, "Like Em' Young", is driven by a tribal-influenced rhythm "coated" with a "parade" of dub-bass.

Its lyrics are satirical in nature, as she criticises other women for judging her taste in younger men: "Hey girl, why you judging me/When your, your guy is turning 53?/ I don't know what gets you more/Is it that my guy's gonna live out yours?" "Talking Body" is a sexual song described as "salivating with carnal lust", according to Ken Capobianco of The Boston Globe, evokes "the rush of early Madonna." Lyrically, the verses see Lo in a state of idée fixe towards her partner, as she finds herself revolving her life around him. The chorus is musically armed with heavy propulsion combined with rising, subdued synths and sees her "objectifying" his model physique. Rounding out the first section is "Timebomb", a frantic electronic dance piano ballad hybrid described as a "sonic bombardment" of "euphoric" chords and psychedelic synths, features an "explosive" chorus containing crashing cymbals and pounding bass. Lo's vocals in the track are sung out of time to the beat; the second section, "The Love", has been described as "a thunderous yearning through gigantic mid tempo, electronic balladry".

It opens with the "volcanic" ballad "Moments", which boasts atmospherics and influences of "trippy" samba. Lyrically, it sees Lo confessing her flaws before declaring "On good days, I am charming as fuck!". "The Way That I Am" is a dubstep song filled with "pain and passion" as Lo sings in a soulful rasp and lyrically cries out to her partner to love her as she is. "Got Love" is one of the albums "pure" pop moments, contains an unwaveringly positive attitude. Lyrically, she rejoices exultant feelings of first falling in love as she sings "Good enough to make the ocean look like it's a pond/Good enough to turn the valleys into mountain tops", discusses the theme of immortality "We live like legends now, know that would never die/Oh, we Got Love". Closing out the section is the power pop song "Not on Drugs". A guitar-driven song that explores the topic of a feeling of love so bewildering and overpowering that it affects your behavior, as if you were on drugs; the final section is "The Pain" which explores the difficulty piecing together one's life after the destruction and demise of a relationship through "distraught" lyricism and melancholic pop.

The section opens with the "thunderous" electropop power-ballad "Thousand Miles", which lyrically depicts Lo's obsession with reuniting with her lost love at all costs if it means running "a thousand miles". Musically, the mid-tempo track tells a story of a girl "strug
