Musical instrument, having a device for tuning tuning bodies, method for retuning a musical instrument and use of a musical instrument

Method for retuning a musical instrument having a device for tuning tuning bodies (1), the method comprising:

• a) providing the musical instrument, the musical instrument including:
• a device for tuning tuning bodies (1);
• at least 12 mechanical tuning elements (2) or tuning element systems (2′);
• the 12 mechanical tuning elements (2) or tuning element systems (2′) represent the 12 chromatic notes of an octave;
• in each case a tuning element (2) or tuning element system (2′) is in mechanical operative connection with at least one tuning body (1);
• exclusively octave-related tuning bodies are associated with each tuning element (2) or tuning element system (2′);
• during tuning of the musical instrument, the tuning elements (2) or tuning element systems (2′) are actuated or actuatable independently of one another;
• the tuning elements (2) are designed as tuning levers and/or the tuning element systems (2′) are designed as tuning lever systems;
• a tuning lever system has at least two tuning levers that have differently located pivot points (4), wherein the tuning levers are slidingly connected to one another via adjacent pivot points (4), and the geometric arrangement of the operative connections of the octave-related tuning bodies (1) and the associated elements (2) in relation to one another is configured in the manner of an intercept theorem;
• and
• b) retuning the musical instrument.

• and
• c) using the musical instrument for playing in any musical key of the circle of fifths, defined with regard to tempered tuning, in pure tuning by means of retuning while playing;
• and/or
• for playing in such a way that during tuning, all intervals of a chord and all chords may be rendered in pure tuning relative to one another.
