According to the invention, a musical instrument having a device for tuning tuning bodies is disclosed, a) having at least (12) mechanical tuning elements or tuning element systems, b) wherein the (12) mechanical tuning elements or tuning element systems represent the (12) chromatic notes of an octave, c) wherein in each case a tuning element or tuning element system is mechanically operatively connected to at least one tuning body, d) wherein each tuning element or tuning element system has exclusively octave-related tuning bodies associated with it, e) wherein during tuning of the musical instrument the tuning elements or tuning element systems are actuatable or actuated independently of one another, wherein the tuning elements are embodied as tuning levers and/or the tuning element systems are embodied as tuning lever systems, wherein a tuning lever system has at least two tuning levers that have differently located pivots, wherein the tuning levers are slidingly connected to one another by means of adjacent pivots, and wherein the geometric arrangement of the operative connections of the octave-related tuning bodies and the associated tuning elements in relation to one another is configured in the mariner of an intercept theorem.

The invention provides a method, system and tuning devices for reed and flue pipes for automatically tuning or checking the tuning of a pipe organ. The invention enables the tuning of the reed pipes to the same pitch as flue pipes if the fluctuation of temperature and humidity has caused a change in the pitch of the flue pipes, and to restore the tuning of the reed pipes in case of random loss of tuning. The invention allows to reduce the tuning time and to tune the pipes that require more frequent tuning (i.e. the reed pipes) unobtrusively to the organist and listeners during the playing of the organ. It is possible to employ the method of the invention on all pipes of an organ or only on a selection of them.

A keyboard apparatus includes: a key disposed so as to be pivotable with respect to a frame; a first member, an elastic member being disposed on at least a portion of a surface of the first member; a second member configured to be moved on the elastic member while elastically deforming the elastic member in response to pivotal movement of the key; and a hammer assembly connected to the key via the first member and the second member so as to pivot in response to pivotal movement of the key.

A keyboard device capable of securing a wider rotation region of a hammer is provided. The keyboard device includes: a key; a connection portion connected between the key and a frame, the connection portion including: a first region extending in a key-longitude direction and having a depressed portion caved upward; and a second region arranged so as to line up with the first region in the key-longitude direction, located in at least a part of a region other than the depressed portion, having flexibility in a yawing direction; and a hammer mechanism operated according to a strike of the key. A part of the hammer mechanism is positioned in the depressed portion in a state where the key is struck.
