Unlike mechanical note production, high-quality piano timbre is achieved through scientifically calibrated key pressure, angle, velocity, and force application patterns, enabling dynamic control. However, many performers currently exhibit limited understanding of key-striking techniques, rigid technical habits, and imbalanced force application, which often results in thin, harsh timbres lacking depth and layering—thereby failing to align with the artistic core of the repertoire. From a practical performance perspective, this paper explores the intrinsic relationship between key-striking techniques and timbre control, analyzes the key issues encountered in everyday performance practice, and—considering the demands of diverse musical styles—proposes targeted optimization strategies for key-striking techniques. This work aims to provide actionable guidance for piano performers to enhance their timbre control capabilities and achieve precise emotional conveyance in their performances.Piano performance, Timbre control, Key-press technique, Technical optimization
