拉威尔是法国杰出的配器大师，他不仅创作了许多优秀的器乐独奏曲和管弦乐作品，还擅长改编作品。《大圆舞曲》就是具有代表性的钢琴改编曲。这首乐曲是他的晚期作品，能充分反映他音乐风格的同时，在创作背景和创作手法上也具有十分特殊的意义，值得我们作为钢琴改编曲的范例进行研究。

由于是管弦乐作品改编而成，拉威尔不可避免地将交响化思维带入到钢琴创作中。因此我们在学习和研究钢琴改编曲时，也要从交响化的角度来分析整首乐曲。本文以《大圆舞曲》为例，通过比较钢琴独奏与管弦乐版本，从中研究交响化思维对拉威尔钢琴作品演奏的借鉴意义，并且从谱面分析、技巧的特殊处理、复节奏对位、音色模仿、触键以及踏板六个方面总结演奏拉威尔钢琴作品时需要如何运用交响化思维，同时希望为演奏者学习拉威尔其他钢琴改编曲提供理论指导。

Ravel is an outstanding French orchestrator. He has not only composed many excellent instrumental soloworksand orchestral works, but is also good atadaption. "La Valse",one of his late works, is a representative pianoadaption. This workfully reflects his music style, and it also has unique significance in terms of background and creative techniques.It is a piano arrangement worthy of being studied as a model.

Since "La Valse" was adapted from an orchestral work, Ravel inevitably brought symphonic characteristic into his creating of it. Therefore, whenlearning andresearching piano adaption, we must analyze the whole piece from the perspective ofthesymphony.Thisresearch takes "La Valse" as an example to explore the significance of symphonic thinking tothe performance of Ravel's piano works by comparing the piano solo and the orchestral version.It also summarizes how tothink symphonically when playing Ravel’s piano works from six aspects:score analysis, special techniques, counterpoint of the polyrhythm, timbre imitation of other instruments, touching of thekeyboard andthe using ofpedals. At the same time, I hope to provide theoretical guidance for players to learn Ravel's other piano adaptations.
