The headstock is located at the end of the guitar neck farthest from the body. It is fitted with machine heads that adjust the tension of the strings, which in turn affects the pitch. The traditional tuner layout is "3+3", in which each side of the headstock has three tuners (such as on Gibson Les Pauls). In this layout, the headstocks are commonly symmetrical. Many guitars feature other layouts, including six-in-line tuners (featured on Fender Stratocasters) or even "4+2" (e.g. Ernie Ball Music Man). Some guitars (such as Steinbergers) do not have headstocks at all, in which case the tuning machines are located elsewhere, either on the body or the bridge.

I have checked out Justin's site and found it to be comprehensive and informative. I have always felt that learning about music and especially music theory applied to the guitar, is helpful in finding your own unique voice on the instrument and expanding your creative horizons. Along with his insight into teaching and his fantastic abilities on the instrument, Justin has created a powerful go-to-place for anyone interested in exploring the instrument to their potential. Just don't hurt yourself.

In contrast, regular tunings have equal intervals between the strings,[20] and so they have symmetrical scales all along the fretboard. This makes it simpler to translate chords. For the regular tunings, chords may be moved diagonally around the fretboard. The diagonal movement of chords is especially simple for the regular tunings that are repetitive, in which case chords can be moved vertically: Chords can be moved three strings up (or down) in major-thirds tuning and chords can be moved two strings up (or down) in augmented-fourths tuning. Regular tunings thus appeal to new guitarists and also to jazz-guitarists, whose improvisation is simplified by regular intervals.
Play the A Major. This is another "big chord," sonically. There are several ways to play this. You can use one finger across the 2nd fret of the B, G, and D strings (playing C#, A, and E, respectively), or any other combination of fingers. For this example, we'll use the 4th finger on the B string, 3rd finger on the G string, and 2nd finger on the D string.
Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides."[2] The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas.[3] A 3,300-year-old stone carving of a Hittite bard playing a stringed instrument is the oldest iconographic representation of a chordophone and clay plaques from Babylonia show people playing an instrument that has a strong resemblance to the guitar, indicating a possible Babylonian origin for the guitar.[2]

"With a note of music, one strikes the fundamental, and, in addition to the root note, other notes are generated: these are the harmonic series.... As one fundamental note contains within it other notes in the octave, two fundamentals produce a remarkable array of harmonics, and the number of possible combinations between all the notes increases phenomenally. With a triad, affairs stand a good chance of getting severely out of hand."
Further simplifications occur for the regular tunings that are repetitive, that is, which repeat their strings. For example, the E-G♯-c-e-g♯-c' M3 tuning repeats its octave after every two strings. Such repetition further simplifies the learning of chords and improvisation;[71] This repetition results in two copies of the three open-strings' notes, each in a different octave. Similarly, the B-F-B-F-B-F augmented-fourths tuning repeats itself after one string.[73]
I was lucky enough to meet Justin at the Guitar Institute during a summer school in 2004, and to have some private lessons with him afterwards.  He was the teacher who kickstarted my guitar career and persuaded me that I was ready to join a band.  That was 14 years ago and many dozens of gigs later.  I’m now just finishing a degree in Popular Music Performance.  Justin's online lessons are easy to follow and he has a manner about him which makes you believe that you can achieve.  Where he demonstrates songs, I have found his versions to be consistently more accurate and easy to follow than those of any other online teacher.  On this website you really will find all the skills and information you need to become an excellent musician.  Many thanks. Ian.
Let’s be honest, private lessons aren’t the best idea for college students who are generally tight on budget, time, and commitments. However, that doesn’t mean you should stop learning and practicing. You can still work on the guitar by taking classes or participating in music programs at your college. These tend to be more affordable, more social, and less stressful than trying to fit private lessons into your routine.
A guitar strap is a strip of material with an attachment mechanism on each end, made to hold a guitar via the shoulders at an adjustable length. Guitars have varying accommodations for attaching a strap. The most common are strap buttons, also called strap pins, which are flanged steel posts anchored to the guitar with screws. Two strap buttons come pre-attached to virtually all electric guitars, and many steel-string acoustic guitars. Strap buttons are sometimes replaced with "strap locks", which connect the guitar to the strap more securely.
The California Conservatory of Music offers guitar lessons with the most qualified teachers in the Bay Area at both our Santa Clara and Redwood City schools. Whether you're looking to start your young child with Suzuki guitar lessons, preparing for a college audition, or getting reading for an upcoming concert, we can assist you. We offer the Bay Area’s most comprehensive guitar lessons which include technique, sight reading, music theory, and in addition to the private lessons, we offer ensemble, repertoire, and theory classes on the weekends. For students under the age of 8, we ask the parents to be involved in their guitar lessons and practice at home. To better help parents develop in to this role, the first three lessons are dedicated to the parent education class. The child can then begin their guitar lessons. This helps ensures the student’s success and motivation. 
Inlays are visual elements set into the exterior surface of a guitar, both for decoration and artistic purposes and, in the case of the markings on the 3rd, 5th, 7th and 12th fret (and in higher octaves), to provide guidance to the performer about the location of frets on the instrument. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette. Inlays range from simple plastic dots on the fretboard to intricate works of art covering the entire exterior surface of a guitar (front and back). Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage. Fretboard inlays are most commonly shaped like dots, diamond shapes, parallelograms, or large blocks in between the frets.
What ultimately sets these rock guitar lessons apart from other offerings is the ability to submit a video for review using the ArtistWorks Video Exchange Learning® platform. Paul reviews each submission and records a video response, offering specific guidance to take your guitar playing to the next level. All students can access the Video Exchange library and watch each other’s interactions with Paul. This library is constantly expanding and may contain the key to unlock your playing.
The two most common types of acoustic guitar are the steel-string guitar and the classical guitar. The classical guitar, also known as the Spanish guitar, usually uses nylon strings. Steel-string guitars originated in the United States and are also referred to as western guitar and folk guitar. Steel-string guitars sound louder and brighter than classical guitars, which have a warmer, mellower sound. Steel-string models usually have larger bodies and narrower necks, and they often have a pickguard to protect the body against scratches by picks and fingernails. Most acoustic guitars have six strings, but there are also 12-string versions. When an acoustic guitar is hooked up to an amplifier, it is referred to as acoustic/electric. Some acoustic/electric guitars incorporate a cutaway design, which makes it easier for electric guitar players to cross over to acoustic.
