"A Certain Someone" is an original composition by Caity Gyorgy from her 2020 debut album No Bounds, featuring vocal and guitar solos over a 36-bar ABAC form in D-flat. Gyorgy's one-chorus vocal improvisation at 152 BPM demonstrates her ability to write compositions that serve as effective vehicles for her own scatting, with the melody and changes designed to inspire creative improvisation. Guitarist Jocelyn Gould follows with one chorus of electric guitar at 154 BPM, her solo navigating the original chord changes with the same fluency she brings to standards. The composition reveals Gyorgy's talent for writing tunes that sound as natural and inevitable as classic standards while bearing a distinctly contemporary harmonic sensibility. The ABAC form provides structural variety that keeps both soloists engaged, with the contrasting B and C sections offering different harmonic environments to explore. The interplay between voice and guitar throughout the album suggests a musical partnership built on deep mutual understanding, with Gould's accompaniment and solo work consistently complementing Gyorgy's vocal conception. The track is a highlight of the album's original material.
