A spinet is a smaller type of harpsichord or other keyboard instrument, such as a piano or organ. ==Spinets as harpsichords== When the term ''spinet'' is used to designate a harpsichord, typically what is meant is the ''bentside spinet'', described in this section. For other uses, see below. The bentside spinet shares most of its characteristics with the full-size instrument, including action, soundboard, and case construction. What primarily distinguishes the spinet is the angle of its strings: whereas in a full-size harpsichord, the strings are at a 90 degree angle to the keyboard (that is, they are parallel to the player's gaze); and in a virginals they are parallel to the keyboard, in a spinet the strings are at an angle of about 30 degrees to the keyboard, going toward the right. The case of a bentside spinet is approximately triangular. The side on the right is usually bent concavely (hence the name of the instrument), curving away from the player toward the right rear corner. The longest side is adjacent to and parallel with the bass strings, going from the right rear corner to a location on the player's left. The front side of the spinet contains the keyboard. Typically, there are very short sides at the right rear and on the left, connecting the bentside to the long side and the long side to the front. The other major aspect of spinet design is that the strings are arranged in pairs. The gap between the two strings of a pair is about four millimetres, and the wider gap between pairs is about ten. The jacks (which pluck the strings (see harpsichord)) are arranged in pairs as well, placed in the wider gap. They face in opposite directions, plucking the adjacent string on either side of the wider gap. The fact that half of the gaps are four millimetres instead of ten makes it possible to crowd more strings together into a smaller case. The disadvantage of the paired design is that it generally limits the spinet to a single choir of strings, at eight-foot pitch, although a double-strung spinet by John Player is known (- references below ). In a full-size harpsichord, the registers that guide the jacks can be shifted slightly to one side, permitting the player to control whether or not that particular set of strings is sounded. This is impossible in a spinet, due to the alternating orientation of the jacks. For an exception to this point, see "spinettone", below. The angling of the strings also had consequences for tone quality: generally, it was not possible to make the plucking points as close to the nut as in a regular harpsichord. Thus spinets normally had a slightly different tone quality, with fewer higher harmonics. Spinets also had smaller soundboards than regular harpsichords, and normally had a weaker sound. For these reasons, the spinet was normally only a domestic instrument, purchased to save money and conserve domestic space. 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「spinet」の詳細全文を読む スポンサード リンク
