Getting the gear that goes with your guitar
Rock guitar does not have a dignified history in music. It doesnât come from a long lineage of historical development where composers such as Bach, Beethoven, and Brahms wrote lovingly for it, composing concertos and sonatas highlighting its piquant and gentle qualities. It was not played in the great European concert halls or in the parlors of fine households.
Not only was rock guitar unknown to the great composers of the ages, but they couldnât have even conceived of such a thing, even in their worst nightmares. (So imagine what they would have thought of an Ozzy Osbourne concert â a nightmare no matter which century you hail from!) Indeed, even if they could have heard, through some sort of time travel, an electric guitar banging out the riff to âSatisfaction,â they would have hardly recognized it as music.
Rock guitar is a modern, late-20th-century invention, a phenomenon of the post-electronic age. It has no memory of a bygone era when youth was respectful of elders, music was a polite pursuit, and musicians gave a rusty E string about social acceptance.
Rock guitar is for people who like their music loud, in your face, electric, and rebellious, and who owe no debt to history. Rock guitar is probably not the wisest choice of instruments to tackle if you want to garner acceptance from the music community.
So, if you want respect, take up the flute. But if you want to set the world on fire, attract throngs of adoring fans, and get back at your parents to boot â pick up an electric guitar and wail, baby, wail, because rock guitar will change your life.
First, though, you gotta learn how to play the thing.
Differentiating Between Rock and Acoustic Guitar . . . It Ainât Just Volume
When you see someone flailing away on rock guitar â on TV, in a film, or at a live concert â be aware that what youâre seeing tells only part of the story. Sure, someone playing rock guitar is holding an instrument with six strings, a neck, and a body â qualities that describe the instrument that classical guitarist AndrĂ©s Segovia played â but the sound couldnât be more different. That difference in sound is the key to understanding rock guitar. Whatâs important is not the leather, the hair, the onstage theatrics, the posturing, the smoke bombs, or the bloody tongues, but the sound coming from that guitar.
It was the sound of the electric guitar, so different from that of its predecessor, the acoustic guitar, and placed in the hands of some early, forward-looking visionaries, that forced a cultural change, a musical modification, and a historical adjustment to the way we experience popular music. Songwriters had to write differently, recording engineers had to record differently, and listeners had to do a major attitude adjustment to get their ears around it. Heck, people even had to learn new dances.
But what makes the sound of an electric guitar so different from an acoustic one? If you didnât think about it, you might say, well, volume. Rock guitar is just a whole lot louder than its acoustic counterpart. Although that might be true most of the time, volume alone is not what makes rock guitar unique. True, rock is listened to at high volumes â its message tastes better served up loud â but volume is a by-product, an after-effect, not what makes rock different or what drives it.
To become familiar with the qualities of the electric guitar, try this simple test. Listen to track #66 on the CD that came with this book. As you listen, turn the volume down so that itâs quiet, very quiet â quieter than youâd normally listen to music, rock, or otherwise. Youâll hear that the guitar sounds, well, just different. In fact, if you have to strain a little bit to make out that what youâre hearing is a guitar at all, youâll be aware that the tone (the quality, or character of the sound, independent of its pitch and volume), in spite of the low volume, doesnât sound like the guitar that your camp counselor strummed around the campfire when she led you in a rousing chorus of âSheâll Be Cominâ Around the Mountainâ or âOh Susannah.â
To really understand rock guitar, you need to explore some of its qualities other than volume. Donât worry, though, the book gets back to volume eventually.
Sound quality, or timbre
When guitarists âelectrifiedâ to their acoustic guitars, they originally intended to give the guitar a fighting chance in the volume department. Unsatisfied with the results of placing a microphone in front of the guitar, they sent the guitarâs sound to a speaker by placing a magnetic element called a âpickupâ under the guitarâs strings. (See âSignalâand âDistortion and sustainâ later in this chapter for more on pickups.) Players quickly found, however, that, unlike a microphone, a pickup didnât just make the sound louder, it changed the tone too. But how? It wasnât that obvious, but it was tangible.
The basic differences between a guitar coming out of a pickup and a guitar playing into a âmikeâ (slang for microphone) are:
The sound is smoother and less woody.
The sound is more electronic, with purer-sounding tones, like that of an organ.
The sound has a less defined life cycle, or
envelope â a beginning, middle, and end. These stages, so clear in the sound of a plucked acoustic guitar string, are blurred together in an electric guitar.
Now letâs explore how electrifying the instrument affected its sound â to the eventual benefit of rock guitarists.
Signal
When progressive-minded guitarists of the â30s and â40s first put electro-magnetic elements under their strings to âpick upâ their vibrations and send them along a wire to an amplifier, they did a lot more than increase the volume â though they didnât know it at the time. They were on their way to creating one of those âhappy accidentsâ so common in art and science (and this was a little of both, really).
Originally, jazz guitarists playing in the big bands of the day were merely seeking a way to cut through all the din of those blaring horns and thundering drums. The mellow guitar, regarded by most other musicians as a mere parlor instrument with dubio...
