Luthiers are skilled craftsmen who work with wood to create stringed instruments such as guitars, violins, and cellos. They use various tools and techniques to shape the wood and assemble the instrument. A luthier’s job is not only to make the instruments, but also to repair and customize existing ones.

In this article, we’ll take a look at what a luthier does and the different types of instruments they work on:

Luthier What Do They Do(v5u0)

Definition of a Luthier

A luthier is a skilled craftsman or craftswoman who builds and repairs stringed instruments, primarily those belonging to the violin family. The term “luthier” was first used in France in the late seventeenth century, but the trade has existed since the Renaissance.

It was during this time that craftsmen began creating custom-made instruments for mass-produced instruments of lesser quality.

The craft of lutherie involves taking an instrument apart, assessing its components and their condition, building it up with the appropriate materials and tools, adding varnish and tuning it correctly to make sure it is in proper working order. It requires knowledge of:

  • how to create a variety of shapes and sizes
  • how to use different types of woods
  • how to seal them properly to safeguard against weather changes and natural elements
  • how to use different types of strings on an instrument

Additionally, luthiers also need to be able to tune these instruments precisely so they can be played at their best sound quality.

What Do Luthiers Do?

A luthier is a craftsman who builds and repairs string instruments such as guitars, violins and cellos. In addition to being artisans, they also need to understand the physics and mechanics of these instruments in order to make adjustments and repairs.

Let’s take a closer look at what luthiers do and why it is such an important profession:

Repair and Maintenance

Luthiers repair and maintain stringed instruments such as violins, guitars and banjos. They make sure these instruments are playable and in good condition when they are sold to their clients. This may include changing the strings or tuning the instrument, as well as making repairs to any damaged or worn-out parts of the instrument.

To do this job correctly, luthiers must have a high level of skill and expertise in working with wood and other materials used in stringed instruments. They must also be knowledgeable on how different types of string instruments should be set up.

Some luthiers specialize in repairing vintage instruments like violins from centuries-old Italian masters. These luthiers often work closely with music conservatories to identify antique pieces for restoration. Many of these instruments sell for thousands of dollars at auctions around the world once they have been fully restored by a skilled luthier.

In addition to violin repair and maintenance, some luthiers offer services like:

  • Guitar lessons
  • Instrument rentals
  • Custom builds or modifications for existing instruments
  • Custom design work for those looking for something unique from their instrument maker.

Building and Customizing Instruments

Luthiers are craftspeople who specialize in the construction and building of stringed instruments, usually guitars, violins, and banjos. This job requires a great deal of skill and expertise in working with wood and other materials used to build the instrument. This process involves the design and making of not only the body of the instrument but also its neck and headstock components. Luthiers must also have knowledge of woodworking tools such as power saws, planers, routers, drill presses, glues, clamps, etc., as well as smaller tools such as files and chisels.

The crafting process also includes customizing instruments according to their desired purpose or sound character by adjusting or replacing frets or bridges; refinishing woodwork; or making mechanical modifications such as adding pickups or tone-controls to improve sound quality. A luthier may also specialize in building copies of vintage instruments in order to replicate those sounds. In addition to these duties, luthiers often perform maintenance on instruments by performing basic repairs like cleaning fretboards or replacing strings if necessary.

Setting Up Instruments

A luthier is an artisan who works with stringed instruments such as guitars, violins, cellos, dulcimers, mandolins and other instruments in the same family. Many of these are acoustic instruments assembled from parts and materials such as wood and steel. A luthier must possess a diverse range of skills in order to properly maintain and repair these instruments.

One of the tasks for a luthier is setting up or constructing the instrument from scratch. This involves assembling all the necessary components like bridges, tuning pegs, strings and pickups to name a few. Luthiers will be conversant in different finishes such as varnish or nitrocellulose lacquer that help to produce a high-quality sound. They are also knowledgeable about woodworking techniques such as jointing and routing depending on the maker’s preferences.

The luthier must also check and adjust an instrument’s intonation – making sure that all notes on different strings have been set correctly according to pitch and harmonic response – so that it can produce a pleasant sound when played. Neck adjustment is another crucial tip that might include relief adjustment or truss rod adjustment for better playing accuracy which helps to ensure clear intonation quality in any note on any string at any point along its length when played with any type of pick-up selector switch setting (for electric guitars).

Ultimately, the long term goal is for each instrument’s components work in perfect harmony so that all types of musicians from amateur levels to expert musicians can enjoy an enjoyable listening experience from it!

Types of Instruments

Luthiers specialize in the construction and repair of stringed instruments such as guitars, violins, and cellos. Within the field of stringed instruments, there are a wide variety of types and styles. Examples of types of instruments include acoustic, classical, and electric guitars. Each type has its own unique features and tonal qualities, so it is important to understand what each type of instrument can do.

In this article, we will cover the various types of instruments that luthiers specialize in:

Stringed Instruments

Luthiers specialize in the stringed instrument family – their expertise covers everything from the making, repairing and restoration of instruments to the intricacies of sound production. Whether you’re getting a sitar repaired or a new ukulele built, your luthier knows their stuff. Here’s a basic rundown of the stringed instruments they could be responsible for:

  • Guitars – Guitar repair, setup and building is at the heart of most luthier work. From minor repairs to building custom instruments from scratch, they can handle it all. Guitars come in many shapes, sizes and designs but there are essentially four main types you should know about: acoustic, classical or Spanish style guitars; electric guitars; archtop guitars; and resonator guitars.
  • Basses – Just like with guitar repair and setup, your luthier also handles bass setup. It’s important to keep bass strings sounding their best as well! There are two main types of bass – electric basses and double basses – so make sure you bring your instrument with its correct specs when getting it serviced by a luthier.
  • Banjos – Banjos come in many different varieties such as open backed banjos, five-string banjos, plectrum banjos and tenor banjos which are all great for traditional folk music styles such as bluegrass music or old-time Appalachian fiddle tunes. If this type of instrument needs repairs or you want to get a custom-built one made then make sure that your luthier has experience with handling this type of work because there’s more than just strings involved!
  • Mandolins – Mandolins come in two main styles – F-style (which looks like an ‘F’ when viewed from above) or round-hole (which have eight round holes). Both have x-shape bodies that lend themselves to being played with picking techniques similar to those used on guitars but mandolins require thinner gauge strings to accommodate their shorter scale lengths which is something that only an experienced luthier can handle correctly! And if you ever want mandolin parts replaced like the tuning headstock pegs or the bridge then look no further than your local luthier for any servicing needs.

Wind Instruments

Wind instruments are a group of instruments that require the player to blow into them in order to create sound. While some wind instruments have the ability to be amplified, they require no electricity or electronic components to produce sound. Wind instruments typically consist of tubes of varying lengths and sizes and have mouthpieces through which air needs to be directed by the player in order for sound to be produced. The majority of these instruments use brass, woodwinds, and reeds/membranes.

Common wind instruments include:

  • Brass family (trumpet, trombone, tuba);
  • Woodwind family (flute, clarinet, oboe); and
  • Reed family (saxophone).

Brass instruments make a loud resonant sound while woodwinds are softer in volume with more “woody” timbre similar to stringed instruments. Reed family members use either single or double reeds that vibrate when air is blown through them creating the unique tones associated with jazz music.

The luthier is an experienced technician or craftsman who specializes in constructing or repairing wind instrument parts like bells, keys/valves, and mouthpieces for optimum playability as well as ensuring acoustic correctness in terms of intonation. Luthiers may also be equipped with skills necessary for repairing existing dents or cracks on wind instrument body pans as well as fabricating custom fitting cases and stands. As there are many small components involved in constructing each piece they must take great care and dedication when building each instrument part causing this job to require a very high level skill set that takes years to acquire!

Percussion Instruments

Percussion instruments are used to create a wide range of musical sounds by way of striking, shaking or scraping. They can be either tuned or untuned and their range of tones are produced through three methods; vibration, contact and friction. Commonly known as the backbone of a musical ensemble, percussion instruments provide an essential rhythmic foundation for melodies and harmonies to develop.

Tuned percussive instruments include drums such as timpani, congas, assorted drums such as marching snare drums, bongos and hand-sized tom-toms. These are formed from a variety of materials including metal, wood, hard plastic or ceramic. Most often requiring some tuning by the luthier prior to use in order to resonate appropriately within the muiscal environment they will be used in. Un-tuned percussion instruments come in various forms such as wood blocks, tambourines and ratchet rings: these generate their determined pitch based on the length or size of material employed rather than through tuning by a luthier.

The frequency at which sound is emitted depends upon the mass of material used in its construction (shell) and its tension (head). Head tension is typically adjusted with a drum key while shells are typically constructed with woods like maple or birch depending on desired specifications such as volume and timbre therein desired. It should be noted that some drums have additional mounting hardware incorporated into their design allowing additional tones to be produced when struck around additional parts thereof – most notably wind chimes or cowbells mounted onto Surdo Drums found within Latin influenced music genres.

By working closely with experienced luthiers an array of percussive tones can ethically crafted for any purpose thereby improving performance for both amatuer musicians looking to make an impression on stage or recording professionals seeking specific resonances dueing production efforts therein facilitating better output from rehearsals onwards having applied diligent improvements from greater levels of precision ultimately provided through experienced luthiary services available globally today!

Tools and Materials Used

Luthiers, or guitar makers, create instruments from scratch, repairing and refurbishing existing instruments, and performing modifications to existing instruments. To do their job, luthiers use a variety of tools and materials.

Common tools used by luthiers are saws, files, drills and screwdrivers, and sanders. Other materials used by luthiers include woods, screws and bolts, glue for adhesion, and an assortment of decorative inlays such as mother of pearl or abalone.

Let’s explore these materials and tools in more depth:

Woodworking Tools

Luthiers must have an intimate knowledge of a variety of woodworking tools in order to create instruments with the desired sound quality and appearance. Depending on the type of instrument you’re creating, wood selection is paramount, as it can affect various aspects such as density and weight.

To prepare for construction and work with available pieces of wood, luthiers must master the use of several tools including saws, files, hammers, chisels, drills and routers. These tools allow them to shave down excess material, shape pieces into desired shapes and integrate parts with precision. Additionally, many luthiers use hand planes and lathes to refine the surface texture and produce parts which help creators bring their ideas to life.

Finally, there are other specialized materials which are used in construction including:

  • Glue for joining disparate materials such as wooden boards or animal hide.
  • Varnish for sealing surfaces.
  • Pegs or posts for connecting different components.
  • Strings or wires for vibration sound production.
  • Pick guards that protect surface finishes from wear.
  • Different oils applied to wooden surfaces to enhance the grain patterns or tone qualities.
  • Frets which provide tension-release points when pressing strings against them while maintaining desired intervals between notes.

All these components and materials create a unique recipe enabling luthiers to send their finished creations into the world!

Metalworking Tools

Luthiers use specialized tools designed for shaping metal to make and repair string instruments. Metalworking tools include a variety of saws that cut metal, including bandsaws and scrollsaws; drill presses for drilling holes at certain depths with accuracy; grinders, which are used to grind away metal to shape an instrument; and MIG welders which can be used to join metal parts together. Additionally, machines such as shears, brake presses and punch presses enable luthiers to bend, cut and form an instrument’s metal components.

Power sanders, polishing wheels and dremels are all essential pieces of equipment needed when creating inlaid designs into frets or the back plate of the instrument. Other essential tools include:

  • Tool boxes to store supplies safely and easily.
  • Calipers for measuring parts accurately.
  • Aprons to protect clothing during work sessions.
  • Vises for working on instrument repairs with two hands free.
  • Magnifying lamps for detailed checkout of the workpiece.

Specialty Tools

Specialty tools are often required when creating and shaping custom guitars. Many of the specialized tools used by luthiers have unique designs that make them easy to use when dealing with the smaller parts of a guitar or bass.

  • Pointer planes – These planes are typically used for truss rod adjustment, as well as for removing wood strips from the waist area of acoustic guitars and hollow body electric guitars.
  • Crowning files –these files are designed specifically to shape and sculpt acoustic guitar saddles. They come in a range of sizes, from small double-gouge to large triple-gouge, giving luthiers flexibility when working with particular instruments.
  • Rasps – These handy metal cutting files allow luthiers to quickly shape wood, laminated parts and plastic fretboards with precision.
  • Dremel tools – Rotary tools such as a Dremel are invaluable because they fit very well into tight areas, making it easier to craft unique shapes while minimizing extra sanding time.
  • Strummingi metal cutters – Used to cut slots in truss rods so that they can be adjusted accurately on the guitar neck.
  • End scalers – A must-have tool for cutting binding materials off the body or neck where it is intertwined with the sound hole on an acoustic instrument.

Education and Training

Becoming a luthier or a maker of stringed instruments is no small feat. It requires a great deal of education, knowledge and experience to be successful. It’s important to understand the basics of woodworking, metalworking and understanding of the mechanics and acoustics of instrument building.

In this section, we will cover the education and training required to become a luthier.


Apprenticing with an established luthier is a great way to gain the experience needed to become a successful and reliable luthier. Apprenticing programs vary in length and style but typically involve being given hands-on tasks by your mentor, field trips to view master craftsman’s work, and accompanying your mentor to various instrument repair and design appointments. An apprenticeship can also provide access to tools, materials, and contacts that may otherwise be hard or impossible to acquire.

By working daily with an experienced professional, you can learn the techniques and skills necessary for restoring instruments as well as building new ones. You’ll learn how to select quality materials and expertly shape them into functional musical instruments. You’ll also gain valuable insight into the distinct creative process involved in dreams up original designs, putting plans into action, problem solving technical issues, understanding customer needs and wants, meeting deadlines, among other important career milestones.

Formal Education

Becoming a luthier is not a short path. It requires patience, determination, and hard work. Many luthiers gain their skills through formal education from trade schools, or from an apprenticeship with another luthier.

People who want to become luthiers usually need to specialize in two- or three-year long training programs offered by specialty trade schools and advanced musical instrument design programs that often include specializations in electric, acoustic and bass guitar designs as well as mandolins and violins. These specialized training programs also often introduce students to the history of string instruments, teaching them the skill of craftsmanship, repair techniques and physics of sound waves.

Apart from beginning skills such as sawing, carving, sanding and joining pieces together with glue or screws, students may also need to develop their own tools such as screwdrivers, pliers and saws.. After graduating within two or three years they may be able to start repairing stringed instruments professionally. In order to do more complex repairs some luthiers will have to collaborate with specialist repair teams for instrument remodeling projects that involve reshaping the necks or bodies of guitars as well as making electronics adjustments on electrics guitars and special finishes for guitars and woodwinds instruments.

To stay up-to-date on new building materials or technologies many veteran luthiers take advanced courses to readjust their skills for current market demands. This ongoing education helps them ensure accuracy in repairs without compromising the original designs of vintage instruments.


In the field of luthiery, there is no single standardized set of certifications that guarantee competency in this profession. Many successful luthiers have learned their skills from apprenticeships with experienced craftspeople or by undertaking self-directed study. But certifications are available through certain educational institutions and organizations, providing a more formalized structure to acquiring the necessary knowledge and skills.

Certification options include:

  • Certificate Programs in Luthiery offered at select technical and trade schools. These programs provide an intensive introduction to the concepts and techniques used in high-grade guitar building, focusing on electric or acoustic guitars.
  • Licensed Practitioner Certification, awarded by the American Institute of Guitar Building after you pass a series of exams demonstrating mastery of specialized skills, including construction methods and repair techniques for both acoustic and electric instruments.
  • Certified Luthier credentials provided by Certainteed Guild of Guitarsmiths (CGG). This credential is awarded after completing a demanding program designed to test technical knowledge as well as practical application for various aspects of building stringed instruments like guitars.

For aspiring luthiers who have no formal instruction, ongoing professional development through seminars, workshops, conferences and other instructional opportunities can help them stay informed on new trends in their field as well as learn more about materials and methods used in instrument making.
