Takekuni Hirayoshi's "Ballerina's Sorrow" is a work notable for its irregular meter and delicate nuances. It is written entirely in 5/4 time. The composer advises that the staccato on the fifth beat should not be played too strongly. Especially in the right hand, playing with a soft, upward wrist motion will make the staccato sound as if it gently melts into space. Similarly, the staccato in the left hand should be played while maintaining a light and soft nuance.

From measure 6 onwards, the sense of meter gradually changes. It is advisable to focus on the musical coherence, using articulation as a guide, rather than being constrained by bar lines. As the beat unit changes from five to four, and then to two beats, a sense of urgency gradually increases, and the music becomes tense. This tension then eases, and at the poco rit. in measure 9, written in 6/4 time, the music shows a brief expression of relief, as if taking a breath.

In measure 10, the opening melody reappears, returning to a calm flow for three measures. The subito f that appears at the end should conclude with an unwavering and resolute sound. Throughout the piece, it depicts an inner emotional fluctuation, and should be played with a soft tone, emphasizing the dance-like rhythm.
