improvisatory

1.Piano improvisatory accompaniment is not only a subject including composition and performance but also a practical performing art.

钢琴即兴伴奏既是创作与演奏为体的综合学科,同时又是实用很强的表演艺术。

2.Also, if the improvisatory accompany is too high or too low, the time and power is not suitable, the music will no a tune and less the beauty of strewing and harmonious.

如若左手伴奏音高当，时间对，力度足，又可能使整个音乐够协调，缺少错落与和谐之美。
