The claviorganum (also known as the claviorgan, or organised piano) is a combination of a harpsichord and an organ. Its origin is uncertain. A number of "virgynalls with regals" are mentioned in the inventories of Henry VIII in 1542/3 and 1547 and Wilson Barry 〔Wilson Barry (1990: 38)〕 cites references to the claviorganum in England dating back to the 1530s. The term ''claviorganum'' in its strictest sense refers to the combination of a harpsichord (or other harpsichord type instrument) and an organ, although later could also be used to refer to a combination of a piano and organ. Michael Praetorius describes the claviorganum in his Syntagma Musicum of 1619 as
==Description== The spinet-regals are usually quite compact, especially compared to their larger harpsichord cousins. The spinet is often of the smaller Italian style in a square case, as opposed to the perhaps more familiar Bentside shape popular in Britain. The organ is usually a small regal, with the bellows perpendicular to the keyboard, and pipes with tiny resonators. The larger harpsichord instruments seem to have been quite popular in Britain in the eighteenth century. Out of twenty-four instruments found so far, eleven were either made in the UK or spent the greater portion of their playing life in Britain. These instruments mostly have a harpsichord-shaped organ case which sits neatly below the harpsichord and can be coupled to the lower of two harpsichord keyboards or played separately. The most complete British instrument is the owned by the Earl of Wemyss. The harpsichord is typical of the early and ornate work of Jacob Kirckman, with an organ case that matches the marquetry and elaborate figured veneer of the harpsichord. The harpsichord stop levers are laid out in the conventional fashion on either side of the name-board, with the organ stops being placed at either side of the keyboards with a coupling mechanism to the organ at the front of the harpsichord. The organ case is also fitted with four foot-levers; three at the front of the organ and one at the side of the case. Two of these are for operating the bellows (one main and one auxiliary), the third shuts off the sliders of the two metal ranks achieving a woody sound, and the final lever operated a kind of swell mechanism opening a sprung panel in the side of the instrument. This allows for quite a lot of variation in timbre between the organ and the harpsichord. How typical the arrangement is of instruments across Europe and the ages is difficult to quantify, as little is still known about this instrument. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Claviorganum」の詳細全文を読む スポンサード リンク
