A Certain Someone is an original composition by Caity Gyorgy, first recorded for her debut album No Bounds in 2020. The tune is a medium-up swinger in Db major built on a 36-bar ABAC form, giving it a slightly asymmetrical structure that extends beyond the standard 32-bar template. The extra four bars in the final C section allow the melody to develop a bit further before resolving, lending the form a natural sense of narrative arc well suited to a vocal lyric. On the No Bounds recording, the arrangement features Gyorgy's voice alongside Jocelyn Gould on electric guitar, with both musicians taking improvised solos over the changes. Gould's presence gives the track a warm, rounded tone that complements Gyorgy's clear vocal delivery. Like much of Gyorgy's original writing, the composition reflects her affinity for the classic swing-era songwriting tradition while incorporating her own melodic and harmonic sensibility, fitting comfortably alongside the mix of originals and standards that make up the album.
