Standard tuning is the most common tuning for a six-string guitar, where the strings are tuned to the notes E, A, D, G, B, and E, from the lowest (6th string) to the highest (1st string). This tuning allows for a wide range of chords and melodies, making it accessible for beginners and versatile for various music styles. In standard tuning, the intervals between the strings are consistent, which helps players easily navigate the fretboard. Many popular songs and genres, including rock, pop, and blues, utilize standard tuning, making it a foundational skill for aspiring guitarists.
