Takekuni Hirayoshi's "Rusty Swing" is, as its title suggests, a work with an impressive atmosphere that is both nostalgic and melancholic. The composer states that he wishes listeners to enjoy the sounds of the suspensions and their resolutions that appear throughout the piece, thus requiring careful attention to each harmonic progression during performance.

In sections employing three-voice writing, the aim should be to create a three-dimensional sound, mindful of the differences in timbre and volume among the individual voices. Particularly, as the left hand simultaneously carries both the bass and middle voices, care must be taken to ensure the bass notes are not cut short; practicing the left hand alone is also effective. In measure 5, the tenor voice moves in parallel, closely accompanying the soprano in the right hand; this section should be played with an emphasis on smoothness, as if two people are singing together.

From measure 13, the texture reduces to two voices, expanding into a simple yet dialogic sound. In measure 17, a modulation occurs from C major to A minor, and the left hand reintroduces the opening melody. Here, the right-hand accompaniment carries a rhythm like a gentle sway; it is advisable to support this with a subtle nuance, allowing the sway to feel natural, even during the quarter rests.

From measure 25 onward, the piece builds towards its climax. In particular, the highest note, B, extended by a tie, should resonate expansively, played with a sense of inner feelings being released. Thereafter, the mood naturally returns to a calm expression, and the entire piece concludes in a gentle lingering resonance. Throughout the work, it should be performed with a nostalgic sentiment befitting the gentle swaying of a swing and the accompanying adjective "rusty."
