Guitar chord in the abstract musical-theory of chords for all instruments. For example, in the guitar (like other stringed instruments but unlike the piano), open-string notes are not fretted and so require less hand-motion. Thus chords that contain open notes are more easily played and hence more frequently played in popular music, such as folk music. Many of the most popular tunings—standard tuning, open tunings, and new standard tuning—are rich in the open notes used by popular chords. Open tunings allow major triads to be played by barring one fret with only one finger, using the finger like a capo. On guitars
Tuning mechanisms for stringed instruments but straight, and they go into straight-sided holes. Like tapered pins, threaded pins must be set in a pin block of fairly hard wood, such as cherry or white oak, or they will not stay in tune well. Some pin block woods come from endangered trees. Some specialized plywoods can also be used (piano pin block stock or the die maker's ply used for rotary dies) Threaded tuners are durable, will take very high string tensions. They do not push outwards on the hole and wedge the wood apart, which can reduce the risk of splitting it. They can be
