Take as a single example this easily overlooked little passage from the rondo of the 23rd piano concerto; it is, in its essence, nothing more than a functional bit of connective tissue taking us from one place to another within the movement's structure. Ten brief bars—about 10 seconds—of basic scalar material, doing its job efficiently and economically. But it is at the same time so richly and amusingly characterized, so full of piping energy, with its determined but struggling piano line climbing its stutteringly inexorable way up to the note E, punctuated along its course by deadpan commentary from the winds, sneaking in the D natural that signals the change of key with almost undetectable sleight of hand—the passage almost constitutes a miniature comic universe all by itself.

请听这段在《第23钢琴协奏曲》中常常被人忽视的回旋曲( http：//img.slate.com/media/87/7_mozart488.asf )，没有哪个功能性连结段能比它更好地仅通过乐章结构就将听众带入另一个世界，长约10秒钟的概要部分(brief bars of basic scalar material)不仅经济有效地发挥其职能，同时又表现出丰富、诙谐的特色，充满木管乐器的活力，伴随着坚决但阻碍不断的钢琴的快速音群移入E大调，其行进过程不时被管乐器部加以修饰、注解，自然而然的转为D大调，转调手法之娴熟几乎无法察觉——这段音乐本身创造出一个微缩的喜剧世界。
