Brief History of Classical Guitars

The modern classical guitar has its origins in Spain in the early 16th century. The earliest guitars were descended from the guitarra moarena and guitarra latina instruments brought over by the Moors after their conquest of the Iberian Peninsula in the 8th century. These early instruments typically had 4 or 5 courses of strings.

By the late 16th century, a fifth course of strings was added, and the body shape started to resemble the modern classical guitar. The vihuela, an instrument with 6 courses of strings, also emerged during the Renaissance period and is considered an important ancestor to the classical guitar.

In the 18th century, the six string single guitar became the norm in Spain and gained popularity across Europe. The design was also standardized - classical guitars were now constructed with fan bracing under the soundboard rather than the earlier lattice bracing.

The 19th century saw the rise of classical guitar virtuosos like Fernando Sor and Francisco Tarrega. It was also a time when famous luthiers like Antonio Torres Jurado made significant improvements in classical guitar design leading to the modern instrument. The key innovations included increasing the size of the body, moving to higher tension strings, and fine tuning bracing patterns.

Over the last century, the basic design of the classical guitar has remained consistent even as construction methods and materials have evolved. It is a testament to the early innovators that their vision for the instrument continues to be relevant today. The rich heritage serves as an inspiration for modern luthiers seeking to follow in their footsteps.

Anatomy of a Classical Guitar

The anatomy of a classical guitar includes several key components that contribute to its distinctive shape, sound, and playing style. The main parts include:

• Body: The body of a classical guitar is larger and has more curvature than other types of guitars. It is made up of the top, also known as the soundboard, the back and sides which form the shell, and internal bracing to provide support. The curved body shape allows for enhanced projection and resonance.

• Neck: The neck is attached to the body and supports the strings. Classical guitar necks are wider than steel-string acoustic guitars to accommodate the wider spacing between strings. They are also built at a slight angle to the body to optimize the playing position.

• Headstock: Located at the end of the neck, the headstock houses the tuning machines. Classical guitars typically have slotted headstocks which hold the strings at a perpendicular angle to the neck. This provides more downward pressure and stability for the strings.

• Tuning Machines: Also called machine heads or pegheads, these allow players to change the tension and tune each string to the proper pitch. Classical guitars use tuning machines with gears to wrap the string around the post.

• Fretboard: The long, thin part of the neck that the strings run above. Classical guitars have a wider fretboard made of either ebony or rosewood. The frets divide the fretboard into half step increments.

• Bridge: The bridge transfers the vibration of the strings into the body of the guitar for amplification. Classical bridges are flatter with less of an arc compared to steel-string bridges.

• Strings: Nylon strings are a defining feature of classical guitars. They produce a mellow, warm tone compared to steel strings. Classical guitars typically have three bass strings made of nylon wrapped around a metal core and three treble strings made of nylon.

The combination of these integral parts creates the sound, look and feel that musicians expect from a high-quality classical guitar. The anatomy allows for rich resonance, comfort while playing, and the ability to create diverse tones and styles.

Woods Used

The choice of woods used in classical guitar construction has a significant impact on the instrument's tone and sound projection. Luthiers carefully select combinations of woods to bring out the ideal tonal qualities.

The most commonly used woods are:

• Spruce - This lightweight and resonant wood is typically used for the soundboard or top wood on classical guitars. Sitka spruce is most common, providing clarity and volume to the guitar's voice.

• Cedar - Has a warm, sweet, and melodious sound. The wood is lighter and more porous than spruce, emphasizing the midrange frequencies. Cedar tops are especially popular for their mellow, intimate tones.

• Mahogany - The most popular choice for classical guitar backs and sides. It has excellent acoustic properties, while adding depth and richness to the sound. Mahogany highlights the bass and treble registers.

• Rosewood - Used for fingerboards and other appointments, rosewood contributes to a more complex, projecting midrange and bright overtones. It has a clear bell-like tone.

• Ebony - Denser and harder than rosewood, ebony provides crisp note definition for the fingerboard. It brings out clear and brilliant treble tones.

The combination of light, resonant woods like spruce or cedar for the top, with deeper rosewoods or mahogany on the back and sides allows luthiers to craft instruments with balanced and nuanced voices. The woods work together to create the coveted classical guitar sound.

Construction Methods

The actual construction or building process of a classical guitar utilizes techniques that have been honed over centuries of lutherie craftsmanship. While some steps utilize modern tools, many stages in the guitar-making process continue to use traditional hand methods.

The foundation of the instrument begins with the complex internal bracing that provides structural support. The bracing patterns and designs vary between luthiers, but commonly involve a combination of fan bracing and radial bracing attached directly to the underside of the guitar top. The choice of woods, such as spruce or cedar, the thickness, and carving of the bracing all impact the finished instrument's sound.

After bracing is complete, the wooden sides of the guitar body are bent into shape using heat and pressure. This challenging process involves carefully joining and gluing together between 10-20 thin strips of wood such as rosewood. Molds help form the sides into the signature curving hourglass silhouette.

The back and top soundboards are then ready to be carved, sanded, and tuned to optimal thickness and shape - a nuanced skill honed over years. The top requires intricate work to match the bracing patterns. Some luthiers still use hand tools at this shaping stage to precision carve the wood.

Finally the neck is attached and the bridge carefully positioned and glued down. The strings are fastened and tuning machines installed prior to a final setup and inspection. While power tools may be integrated into some steps, skilled luthiers rely extensively on hands-on craftsmanship and a discerning ear to create concert-quality classical guitars.

Playing Style and Technique

The classical guitar requires a specialized playing technique due to its construction and design. Unlike steel-string acoustic guitars, classical guitars use nylon strings which have a mellower tone and lower tension. This allows for more nuanced dynamics and articulation when plucking the strings.

The wider neck and fretboard of a classical guitar enables the musician to play with a rounded hand position, facilitating the plucking motion with the thumb, index, middle and ring fingers. The thumb usually plucks the bass notes on the 6th, 5th and 4th strings, while the fingers pluck the treble strings.

Since classical guitarists play with the fingernails rather than guitar picks, they spend significant time shaping and grooming their nails for ideal tone production. The right hand nails are typically grown longer and filed in a rounded curve to achieve clarity in tone. The flesh of the fingertips also directly contacts the strings to produce different timbres.

Vibrato, string bending, harmonics, legato phrasing and other advanced techniques take years of dedicated practice to master on the classical guitar. Proper posture and hand positioning are paramount. The musician's legs support the guitar's body, while the left hand frets the notes along the neck.

This nuanced approach and playing position allows virtuoso classical guitarists to express incredible dynamic range, articulation, emotion and musicality. The construction of the classical guitar enables - rather than hinders - the musician's full creative potential.
