長期以來，二胡演奏藝術在臺灣眾多前輩的努力下，演奏技巧有了長足的發展與進步，惟系統化的教學教材與學理化的演奏理論卻一直未能建立。因此，筆者以〈胡演奏藝術的三個構面〉為題，闡述二胡演奏藝術的認知、訓練與展現三個構面，再從心理、生理與物理三者的關係；基礎、技巧與詮釋的三個層次；創作、演奏與欣賞三者的關係分別敘述之。期盼藉由這個議題的探討，能夠將筆者長期在這個領域所專研的一些心得提出報告，也希望有更多的專家學者能夠關注這方面的研究，好讓二胡演奏藝術能夠早日系統化、學理化。

It has been a long time that Er-hu performance which was contributed by Taiwan's predecessors has rich development and progress. However, the systematic teaching material and academic performance theory has not been established. Therefore, the author aims at the topic, Three Dimensions of Er-hu Performance, to describe the three dimensions of the knowledge of Er-hu performance, training, and showcase. Then I will discuss the relationships of mental, physical and physics, the levels of the base, the skill and the interpretation, and the relationships of composition, performance and appreciation of art. The author expects to represent some reflections over his long-term study of this field based on the discussion of the issue. I also hope that more experts and scholars can devote themselves to the research of this field to make Er-hu performance systematically and theoretically soon.
