介绍（中）	"摇摆"的melodeon或风琴之所以被称为"摇摆"，是因为它必须上下跳动（键盘因此摇摆），才能使风箱发出簧片的声音。乐器通常放在桌子上演奏。这种仪器没有按键，而是有两排按钮，它们的排列方式就像传统键盘一样，有一排自然键，并以两个和三个交替的组偏移意外键技术说明：矩形红木单板套在对角分隔的双波纹管上；带布罩的波纹管皮革；波纹管配有两个弹簧（上部弹簧断裂），因此左侧的压力在波纹管中产生摇摆运动；乐器顶部有两个纵向可拆卸的枫木面板，每个面板上有四个红木衬套的音孔（有些衬套缺失），音孔下方有滑动纸百叶窗，用于钢琴和forte效果，由顶部左侧的喇叭旋钮操作；枫木面板之间的红木条，包含两排象牙色按钮，底部一排24个自然按钮，顶部一排17个意外按钮，意外按钮顶部有黑色圆圈；罗盘F-a2；可拆卸面板下的无黄铜簧片，触摸打开簧片下的小托盘发出声音；簧片是吹出来的，而不是通过吸力发出的声音。
介绍（英）	The "rocking" melodeon or organ received this moniker because it had to be pumped up and down (the keyboard therefore rocking) in order to pump the bellows to sound the reeds. The instrument is normally set on a table to play. Instead of keys, this insturment has two rows of buttons that are laid out in an arrangement like a traditional keyboard with a row of naturals, and offset accidentals in alternating groups of two's and three's. Technical description: Rectangular rosewood veneer case over a diagonally divided double bellows; bellows leather with cloth covering; bellows equipped with two springs (upper one broken) so that pressure on left side sets up rocking motion in bellows; top of instrument has two lengthwise removable maple panels, each with four rosewood-bushed soundholes (some bushings missing), with sliding paper shutters below soundholes for piano and forte effects, operated by horn knob at left of top; rosewood strip between maple panels containing tw rows of ivory button touches, 24 naturals in bottom row and 17 accidentals in top row, the buttons for accidentals having black circles on tops; compass F-a2; brass free reeds beneath removable panels, the touches opening small pallets beneath the reeds to sound them; reeds are blown, not sounded by suction.
