	鋼琴四手聯彈是一種很親密、很溫暖的音樂形式。莫札特小時候經常
		和姊姊一起在鋼琴上「玩」四手聯彈，舒伯特在與朋友的聚會中也常
		以四手聯彈曲來助興。 張懿文在美國伊士曼音樂學院受教於潘妮斯教
		授期間，四手聯彈的歡樂成為師生和同學間彼此情感的交流方式。因
		此，藉著這次的音樂會，讓觀眾一起來感受四手聯彈的趣味性！ 本場
		名音樂會將帶來被稱為四手聯彈始祖的莫札特，他所寫的天真活潑的
		奏鳴曲K381；佛瑞的「桃莉組曲」，是佛瑞寫給德布希第二任妻子的
		小女兒桃莉的一首親密溫馨的珠玉小品；另外，布拉姆斯因為受到舒
		伯特圓舞曲的影響，譜出了十六首優雅精緻的圓舞曲；而捷克作曲家
		德佛札克，則是受到布拉姆斯匈牙利舞曲的啟發，用自己的語言創作
		了充滿民族色彩的斯拉夫舞曲。

解析解

In mathematics, an equation or system of equations is said to have a closed-form solution if, and only if, at least one solution can be expressed analytically in terms of a bounded number of certain "well-known" functions. Typically, these well-known functions are defined to be elementary functions; so infinite series, limits, and continued fractions are not permitted.

For example, the roots of any quadratic equation with complex coefficients can be expressed in closed form in terms of addition, subtraction, multiplication, division, and square root extraction, all elementary functions. However, there are quintic equations without closed-form solutions using elementary functions.

Changing the definition of "well-known" to include additional functions can change the set of equations with closed-form solutions. Many cumulative distribution functions cannot be expressed in closed form, unless one considers special functions such as the error function or gamma function to be well-known. For many practical computer applications, it is entirely reasonable to assume that the gamma function and other special functions are well-known, since numerical implementations are widely available.

Because most practical cases do not have an analytical solution but still have a numerical one, for practical purposes analyticity is not important.

In physics, an analytic solution is a solution arrived at through the use of equations, rather than through a computer simulation or a numerical computation. An analytic solution may be either exact or an approximation. While it is not always possible to get an analytic solution, it is usually favored because it supplements insights on the nature of the problem at hand.
