介绍（中）	帝王管风琴是一种只有一排管子的小型管风琴。每个管道内都有一个薄的黄铜舌（或簧片），当空气被推入管道时，会发出响亮的鼻音。尽管管起到了共振器的作用，但因为在皇家乐器上，管很短，它们对缓和芦苇咄咄逼人的音调几乎没有作用。通常用作连续管乐器，与更典型的室内管风琴相比，帝王号更响亮的音调使其在更大的音乐家群体中使用。作曲家们偶尔会将其指定为黑社会场景，就像蒙特威尔第在《奥费奥》中所做的那样。　技术说明：一个长方形的染色木盒子，里面有一个深色天然木和白色锋利的键盘。钥匙的背面是一系列装有敲击簧片的小木管，通过方形木制通道与风箱相连。风箱是四折的，通过键盘另一端的木把手交替操作。整个乐器放在一个天然木架上。
介绍（英）	The regal is a small pipe organ with a single rank of pipes. Inside each pipe is a thin brass tongue (or reed) that produced a loud, nasal sound when air is pushed through the pipe. Although the pipes function as resonators, because on a regal they are very short they do little to moderate the reeds' aggressive tone. Usually used as a continuo instrument, the regal's louder tone made it of use in larger groups of musicians than a more typical chamber organ. Composers occasionally specified it, as Monteverdid did in Orfeo, for his scenes of the underworld.　 Technical description: Oblong case of stained wood containing a keyboard with dark wood naturals and white sharps. Back of the keys are a series of small wooden pipes fitted with beating reeds connecting with the bellows by means of a square wooden windway. The bellows are four-fold and are operated alternately by means of wooden handles at the opposite end from the keyboard. The whole instrument rests on a stand of natural wood.
