English: Category:Machine heads. Machine head (also referred to as a tuner, gear head, or tuning machine) is part of a string instrument ranging from guitars to double basses, a geared apparatus for tensioning and thereby tuning a string, usually located at the headstock. A headstock has several machine heads, one per string. Non-geared tuning devices as used on violins, violas, cellos, lutes and (formerly) Flamenco guitars and ukuleles are known as tuning pegs.

Nederlands: Categorie:Stemmechaniek. Een stemmechaniek heeft voor elke snaar een in de kop van het instrument aangebrachte wormwielcontructie die een snaar op spanning brengt. Bij instrumenten met taps toelopende stemschroeven, zoals bij vioolfamilie, noemt men de inrichting een knoppenkast of stemschroevenkast, zie: knoppenkasten en Stemschroeven.
