Dated 26, August 1951. In 1948, Yamada sufered from intracranial bleed and was totally paralyzed for a while, nevertheless later he recovered to continue his creative activity until ca. 1963. Among his 97 piano pieces, however, this work dated 1951 is the last one. Similarly, his works for the other genres were mostly written before his paralysis.
As for his earlier piano pieces, this work is characterized with the harmonic instability. Despite of “g-mall” in the title, the chromatic progression, augmented intervals and frequent momentary shift from the main key make the main-key unclear, especially in the frst half of the piece. On the other hand, the motivic relation through the whole work create the unity, which indicates the composer’s sophisticated technique in a whole structure.
