介绍（中）	降E型中音转音器，有九个按键，主体由黄铜制成，可拆卸的环形曲拐，没有调音滑梯，钟有滚边。护腕和护弓简单朴素。与之相关的小型杯形吹口在19世纪中叶，旋转乐是乐队和管弦乐队中流行的低铜管乐器。该乐器的名字来源于希腊语"蛇"和"钥匙"的组合，是对其前身"蛇"的改进。它的关键系统使旋转乐的音孔被战略性地放置，以使它能够更好地演奏。在19世纪后期，转管乐器被大号和其他带有阀门的低音铜管乐器所取代。它独特的鼻音质量与现代大号有着显著的不同，这使得转管风琴成为当代表演管弦乐队的重要乐器。
介绍（英）	Alto ophicleide in E-flat with nine keys, body made of brass, detachable looped crook, no tuning slide, bell has rolled rim. Braces and bow guard are simple and unadorned. With associated small, cupped mouthpiece The ophicleide was a popular low brass instrument in bands and orchestras during the middle decades of the nineteenth century. Drawing its name from a Greek-derived portmanteau of "serpent" and "keys", the instrument was devised as an improvment on its predecessor, the serpent. Its key system allowed the toneholes of the ophicleide to be strategically placed to enable it to play better in tune. The ophicleide was superceeded by the tuba and other low brass instruments with valves in the latter part of the nineteenth century. Its distinctive, nasal tone quality differs significantly from that of the modern tuba and makes the ophicleide an important instrument in period performance orchestras.
