The neck is the part of certain string instruments that projects from the main body and is the base of the fingerboard, where the fingers are placed to stop the strings at different pitches. Guitars, lutes, the violin family, and the mandolin family are examples of instruments which have necks.
The word for neck sometimes appears in other languages in musical instructions. The French term is manche.
neck of a guitar includes the guitar's frets, fretboard, tuners, headstock, and truss rod.

Guitar
The neck of a guitar includes the guitar's frets, fretboard, tuners, headstock, and truss rod. The wood used to make the fretboard will usually differ from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Strings and tuning), and the ability of the neck to resist bending (see Truss rod) is important to the guitar's ability to hold a constant pitch during tuning or when strings are fretted. The rigidity of the neck with respect to the body of the guitar is one determinant of an instrument's quality. Conversely, the ability to change the pitch of the note slightly by deliberately bending the neck forcibly with the fretting arm is a technique occasionally used, particularly in the blues genre and those derived from it, such as rock and roll. The shape of the neck's cross-section can also vary from a gentle curve to a more pronounced "V" shape. (The fretboard is typically gently rounded across its width.)
Marker dots (see Inlay (guitar)) on the face of the fretboard are usually placed at frets 3, 5, 7, 9, 12 (double dot to indicate the octave), 15, 17, 19, 21, 24 (double dot to indicate the second octave). It's also common that there are marker dots on the side of the neck, near the edge of the fretboard, where the player can easily see which fret he or she is on. Sometimes the dots are replaced with bars, the octave positions having a wider bar.
Violin
The neck of a violin is usually maple with a flamed figure compatible with that of the ribs and back. The shape of the neck and fingerboard affect how easily the violin may be played. Fingerboards are dressed to a particular transverse curve, and have a small lengthwise "scoop," or concavity, slightly more pronounced on the lower strings, especially when meant for gut or synthetic strings. Many authentic old instruments have had their necks reset to a slightly increased angle, and lengthened by about a centimeter. The neck graft allows the original scroll to be kept with a Baroque violin when bringing its neck to conformance with modern standard.
Other instruments
The neck of a lute is made of light wood, with a veneer of hardwood (usually ebony) to provide durability for the fretboard beneath the strings.
Attachment
The method of connecting the neck to the body of the instrument varies according by instrument. This ranges from necks that are simply screwed onto the body of the instrument (such as in electric guitars like the Fender Stratocaster) to various types of glued joints.
There are basically four ways of attaching the neck to the body using glued joints:
- With a dovetail joint, where the dovetail is cut into the end of the neck assembly and fits into a mating mortise in the instrument's endblock. This is typically used on acoustic and hollow-body electric guitars.
- With a simpler mortise and tenon joint, which is similar to a dovetail joint, except that the tenon is straight instead of tapered. Sometimes these joints are reinforced with screws, nails or pins. Since this joint is inherently weaker than a dovetail joint, it is usually only found on violins and similar instruments with less string tension.
- With a neck that ends in a "foot" that is glued to the instrument body proper. This method is mostly used in building classical and flamenco guitars. The "foot" is on the bottom of the neck, and affords a large gluing surface to the back of the instrument.
- By making the neck part of the body. This method is used on some solid-body electric guitars, where the piece of wood that is the neck runs the entire length of the instrument and is laminated to the rest of the body. This makes an extremely strong joint.
The two factors in deciding what type of neck joint to use are:
- Strength: will the joint hold under the instrument's string tension without pulling out?
- Repairability: can the joint be easily repaired if needed? While the latter two methods (using a "foot" and laminating the neck into the instrument) create very strong joints, they are not very repairable, and require tearing the instrument apart if repairs are needed.
