A chord is inverted when the bass note is not the root note. Chord inversion is especially simple in M3 tuning. Chords are inverted simply by raising one or two notes by three strings; each raised note is played with the same finger as the original note. Inverted major and minor chords can be played on two frets in M3 tuning.[56][74] In standard tuning, the shape of inversions depends on the involvement of the irregular major-third, and can involve four frets.[75]
Fretboards are most commonly made of rosewood, ebony, maple, and sometimes manufactured using composite materials such as HPL or resin. See the section "Neck" below for the importance of the length of the fretboard in connection to other dimensions of the guitar. The fingerboard plays an essential role in the treble tone for acoustic guitars. The quality of vibration of the fingerboard is the principal characteristic for generating the best treble tone. For that reason, ebony wood is better, but because of high use, ebony has become rare and extremely expensive. Most guitar manufacturers have adopted rosewood instead of ebony.

Paul Gilbert has made Guitar World's "50 Fastest Guitarists of All Time", and his guitar shredding is legendary. Paul picked up his first guitar when he was 5 years old. By the time he was 15, he was featured in Guitar Player magazine. After graduating from the Guitar Institute of Technology (GIT) in Los Angeles, Paul immediately joined the faculty as a guitar teacher. While teaching, he formed the band Racer X and Grammy-nominated group Mr. Big. Paul breaks down his iconic playing techniques and practice drills. He's known for his enthusiastic and approachable guitar lessons, which are founded on decades of experience.
For example, if the note E (the open sixth string) is played over the A minor chord, then the chord would be [0 0 2 2 1 0]. This has the note E as its lowest tone instead of A. It is often written as Am/E, where the letter following the slash indicates the new bass note. However, in popular music it is usual to play inverted chords on the guitar when they are not part of the harmony, since the bass guitar can play the root pitch.
