guitar_wood : Acoustic guitar wood tone

Solid back, solid side and solid top usually provides the best quality of sound - as well as the highest prices. However, affordable alternatives utilize non-solid sides or backs, or even tops - reducing the cost, but it does impact the tone. Laminates (fake wood) are the cheapest, but they generally have poor tonal qualities. While fine for a beginner who is just starting to learn to play - professional musicians or even those who have start to play well just will not be able use a laminate body/top guitar.

There are a number of factors that , you know, determine the tonal properties of wood. In addition, tonewoods respond differently in the hands of different makers. They can also take on different characteristics when used in different models of guitars - even those built by the same maker. Whether a particular wood sounds good or bad ultimately depends on who is doing the listening, so any attempt to sort out distinctions can only be subjective.

Perhaps the most important factor a luthier must take into account is velocity of sound, which refers to the speed at which a material transmits received energy. A luthier must design with materials that facilitate the transmission of vibrational energy. Lively materials, those with a high velocity of sound, or low internal damping make the best facilitators.

Most luthiers (though not all) believe that the wood chosen for the top is the single most important factor in determining the quality of tone of the instrument. It is also interesting to note that the wood itself takes on different characteristics depending on which part of the guitar it's used for. Makers of electric guitars with bolt-on necks have long been aware of the fact that neck and fretboard materials can have a significant bearing on tone. Bridge materials, like fretboards, cannot make or break an instrument, but they serve to enhance or edit the tonal effects of other woods in the guitar's construction.

In conclusion, it is important to remember that wood species can be responsible only for certain aspects of the tone of any guitar (this instrument is used in every form of music, from Classical to Heavy Metal). Equally important are design, skill of the maker, and the quality of each individual piece of wood used. Tonewood selection however, can be a determining factor in the creation of a very special guitar or a guitar designed for a specific purpose.

When used as a top, Mahogany has a relatively low velocity of sound, (compared to other topwoods) considerable density and a low overtone content producing a solid tone and respond best at the upper end of the dynamic range. Mahogany topped guitars have a strong "punchy" tone that is well suited to country blues playing.

When considered as back and sides, Mahogany has relatively high velocity of sound, which contributes much overtone coloration. While rosewood guitars may be thought of has having a metallic sound, mahogany guitars sound more wood-like. The harder, denser examples of these woods can take also on the characteristics of the rosewoods. Mahogany back and sides tends to emphasize the bass and the treble.

Mahogany necks help to create a warmer, more 'woody' tonal range. As bridge material, mahogany imparts the same tonal characteristic as it does when used as neck material, only less so.

Koa

Koa has been used for soundboards since the 20's. This hardwood has a relatively low velocity of sound, considerable density and a low overtone content. Therefore, it tends to produce a solid tone and respond best at the upper end of the dynamic range. Koa has a somewhat more 'midrangey' tone that works well for playing rhythm and truly shines in guitars made for Hawaiian-style slide playing.

For back and sides, Koa tends to behave much like mahogany in terms of adding tonal coloration, but it's emphasis is again more in the midrange.

Brazilian Rosewood

The rosewoods contribute to tone coloration. Brazilian rosewood is known for its high sound velocity and broad range of overtones, also characterized by strength and complexity in the bottom end and an overall darkness of tone in the rest of the range. Strong mids and highs also contribute a richness of tone to the upper registers. Rosewood guitars also have a pronounced reverberant-like tone quality, caused by audible delays in the onset of certain harmonics. While both species exhibit complexity, darkness and a reverberant tone, Brazilian rosewood has tremendous clarity in the bottom end and sparkle in the top.

Indian rosewood is also known for high sound velocity and broad range of overtones, strength and complexity in the bottom end and an overall darkness of tone in the rest of the range. Strong mids and highs also contribute a richness of tone to the upper registers. Rosewood guitars also have a pronounced reverberant-like tone quality, caused by audible delays in the onset of certain harmonics. Indian rosewood has a thicker, more midrange overall coloration.

When used for necks, Indian rosewood can help fatten up the midrange.

Sitka Spruce

Spruce is the standard material for soundboards, the most commonly used species being Sitka. Its high stiffness combined with the lightweight characteristics of most softwoods, makes it a recipe for high velocity of sound. A strong fundamental to overtone ratio gives Sitka a powerful direct tone capable of retaining its clarity when played forcefully. This makes Sitka an excellent choice for topwood for players whose style demands a wide dynamic response and a robust, meaty tone. On the other hand, the lack of complex overtones in Sitka can produce a somewhat thin sound when played with a light touch - of course, depending upon the design of the guitar and the other choices of wood in its construction.

Red Spruce

Red spruce is relatively heavy, has a high velocity of sound, and the highest stiffness across and along the grain of all the topwoods. Like Sitka, is has a strong fundamental, but also a more complex overtone content. Tops produce the highest volume, yet they also have a rich fullness of tone that retains clarity at all dynamic levels. In short, red spruce may well be the Holy Grail of topwoods for acoustic steel string guitars.

Maple

Maple, as a result of its greater weight and lower sound velocity, can be downright flat sounding, a blessing in disguise when a guitar is amplified at high sound pressure levels. This is why maple is the wood of choice for electric guitar tops. West Coast big leaf maple is the softest and lightest of the maple family, with a wood grain that , you know, resembles waves. Aside from a visually breathtaking pattern, the wavy fibers of 'curly' maple reduce the long grain stiffness and vibrate more freely. (This is the secret to the bright, clear powerful sound of the Parker Fly, the only solid-body guitar made with a curly maple body.

Maple necks can impart a bright "poppy" tone that can do much to reinforce the top end of a large-bodied guitar. Fender electrics tend to use maple necks for the aforementioned "bright poppy" tone. Walnut Black walnut tends to lean slightly more in the tonal direction of mahogany, while claro walnut tends toward tonal transparency.

Alder

Alder is a lightweight wood that is highly resonant, producing a full rich tone. When used for solid-body construction, alder provides a very good low end and midrange with the best performance in the lower mid range. Alder also exhibits good high-end characteristics and sustain.

Poplar

Poplar is a string, dense, yet lightweight hardwood that is unusually resonant. Poplar, when used in solid-body electric guitars, has an exceptionally crisp sound, often described as "spirited" and "bouncy" - even "funky." Poplar guitars are ideal choices for players who favor single-coil snap and clean sound. Swamp Ash Swamp Ash, which grows partially underwater, is a lightweight wood with high stiffness (for high sound velocity), famous for its mid-range snarl and biting response.

Basswood

Basswood is light, stiff, and stable, which makes it particularly effective for necks and bass instruments thanks to its excellent low- end response.

Ebony

Ebony, the traditional material found on the necks of violins, classical guitars, and high-end steel strings, has the lowest velocity of sound of all the woods commonly used and has definite damping characteristics. While not a problem for large-bodied guitars mad of red spruce or Brazilian rosewood, it may be something to consider when designing smaller guitars, particularly those using less resonant tonewoods for tops and backs.

It was extraordinarily difficult for an unmarried 16-year-old to raise a child on her own in the mid-1940s. Pat's parents, Rose and Jack Clapp, stepped in as surrogate parents and raised Eric as their own. Thus, he grew up believing his mother was his sister. His grandparents never legally adopted him, but remained his legal guardians until 1963. Eric’s last name comes from Rose's first husband and Pat's father, Reginald Cecil Clapton (d. 1933).

Eric’s mother, Pat, eventually married and moved to Canada and Germany as her husband, Frank McDonald, continued his military career. They had two girls and a boy. Eric’s half-brother, Brian, was killed in a road accident in 1974 at the age of 26. His half-sisters are Cheryl (b. May 1953) and Heather (b. September 1958).

Eric was raised in a musical household. His grandmother played piano and his uncle both enjoyed listening to the sounds of the big bands. Pat later told Eric’s official biographer, Ray Coleman, that his father was a gifted musician, playing piano in several dance bands in the Surrey area.

Quiet and polite, he was characterized as an above-average student with an aptitude for art. But, from his earliest years in school, he realized something was not quite right when he wrote his name as "Eric Clapton" and his parents' names as "Mr. and Mrs. Clapp". At the age of nine, he learned the truth about his parentage when Pat returned to England with his six-year-old half brother for a visit. This singular event affected him deeply. He became moody and distant and stopped applying himself at school. Emotionally scarred by this event, Eric failed the all-important 11 Plus Exams. He was sent to St. Bede's Secondary Modern School and two years later, entered the art branch of Holyfield Road School.

Typical of his introspective nature, Eric looked beneath the surface and explored the roots of rock in American Blues. The blues also meshed perfectly with his self-perception as an outsider and of being "different" from other people. Sometime in 1962, he asked for his grandparents' help in purchasing a £100 electric double cutaway Kay (a Gibson ES-335 clone) after hearing the electric blues of Freddie King, B.B. King, Muddy Waters, Buddy Guy, and others.

In early 1963, Eric joined his first band, The Roosters. Following the band's demise, he spent one month in the pop-oriented Casey Jones and The Engineers. Before turning to music as a full-time career, he supported himself as a laborer at building sites, working alongside his grandfather, a master bricklayer and plasterer.

In October 1963, Keith Relf and Paul Samwell-Smith recruited him to become a member of The Yardbirds because Clapton was the most talked about guitar player on the R&B pub circuit. During his 18-month tenure with The Yardbirds, he earned his nickname “Slowhand” and recorded his first albums: Five Live Yardbirds and Sonny Boy Williamson and The Yardbirds. The band also recorded the single, "Good Morning Little Schoolgirl". But, Eric had not abandoned his serious research into the American Blues. When The Yardbirds began moving towards a more commercial sound with "For Your Love", he quit. His path in music was the blues.

In April 1965, John Mayall invited Eric to join his band, John Mayall's Bluesbreakers. With this group, Clapton established his reputation as a guitarist and earned his second nickname: “God”. It came from an admirer’s graffiti on the wall of London’s Islington Tube Station that boldly proclaimed “Clapton is God.” Eric’s time with the band was turbulent and he left for a while to tour Greece with friends. Upon his return from Greece, Eric rejoined the Bluesbreakers. It was during this time that the now classic Blues Breakers With Eric Clapton was recorded. While with the Bluesbreakers, Eric also recorded a one-off four-track session with a band dubbed “The Powerhouse”. This studio band included John Paul Jones, Steve Winwood and Jack Bruce.

Following Cream's break-up, Clapton founded Blind Faith – rock's first "supergroup" – with Steve Winwood, Ginger Baker, and Rick Grech. Disbanding after one album and a disastrous American tour, he tried to hide from his growing fame by touring as a sideman with Delaney & Bonnie & Friends. While with this outfit, Eric was encouraged to sing by Delaney Bramlett. He also began composing more. A live album from the Delaney & Bonnie tour was released in 1970. Clapton's self-titled debut was released that same year. In the summer of 1970, Eric formed Derek and the Dominos with members from Delaney & Bonnie's band. The Dominos would go on to record the seminal rock album, Layla and Other Assorted Love Songs. A concept album, its theme revolved around Clapton's unrequited love for George Harrison's wife, Pattie. The band would drift apart following an American tour and a failed attempt at recording a second album.

Hit hard by the break up of The Dominos, the commercial failure of the Layla album and his unrequited love, Eric sunk into three years of heroin addiction. Although he rarely emerged from his Surrey Estate, he filled box upon box with tapes of songs. He kicked his drug addiction and re-launched his career in January 1973 with two concerts at London's Rainbow Theater organized by his friend, Pete Townshend (The Who). The concerts represented a turning point in his career. In 1974, he reappeared with a new style and sound with 461 Ocean Boulevard. Eric had become an assured vocalist and composer in addition to a guitar hero.

In 1994, Eric returned to his blues roots with the release of From The Cradle. The album was Clapton's tribute to his musical heroes and contained cover versions of blues classics. 1997 brought an excursion into electronica with the release of TDF / Retail Therapy with Eric posing as X-Sample. In 1998, he released the soul-influenced Pilgrim, his first album of all new material in nine years. In 2000, he continued his love affair with the blues when he recorded an album with American blues legend, B.B. King. Riding With The King was released in June and within three weeks of release, was certified gold. Shortly thereafter, Clapton was back in the studio recording his next solo project. Reptile was released in March 2001. In late 2002, he began to record a new studio album. Work continued through the summer of 2003 and enough material was recorded for two albums. In addition to new solo material, Eric recorded covers of Robert Johnson songs during these sessions. The Johnson songs were assembled and in March 2004, Eric’s tribute album, Me and Mr. Johnson was released. The new solo material is expected to be released in 2005.

In 2005, Eric revisted the past. He, Jack Bruce and Ginger Baker re-formed Cream for four very special reunion shows at London's Royal Albert Hall. The concerts took place at the venue where their farewell shows took place 37 years earlier, in November 1968. In October 2005, the men performed three further concerts at New York's Madison Square Garden.

In his more than 40 year career, Eric Clapton has received many awards. He is the only triple inductee into the Rock & Roll Hall Of Fame (as a member of both the Yardbirds and Cream and as a solo artist). He has also won or shared in seventeen Grammy Awards.
