What is 7-string guitar tuning?

Standard 7-string tuning is B-E-A-D-G-B-E, which adds a low B string below the standard 6-string guitar. This gives you five extra semitones of low-end range while keeping all standard guitar fingerings intact on the upper six strings.

What scales work on a 7-string guitar?

All standard scales work on a 7-string guitar. The B natural minor, B Phrygian, and B Locrian scales are particularly popular in metal. The extended range also makes the harmonic minor and diminished scales more dramatic.

Is a 7-string guitar harder to play?

The wider neck takes some adjustment, but most players adapt within a few weeks. Standard 6-string chord shapes and scales work identically on the top six strings, so existing knowledge transfers directly.

About 7-string Tuning

The 7-string guitar adds a low B string below the standard 6-string tuning (B-E-A-D-G-B-E), extending the instrument's range into bass territory. This extra low end has become essential in progressive metal, djent, and modern heavy music, enabling crushing low-end riffs while maintaining access to standard guitar voicings on the upper strings.

Pioneered by jazz guitarist George Van Eps and later brought into the metal mainstream by Steve Vai and Korn, the 7-string guitar has become a staple of modern heavy music. Players like Tosin Abasi, Misha Mansoor, and John Petrucci have pushed the instrument's capabilities into new territory, using the extended range for complex harmonic progressions, polyrhythmic riffs, and sweeping arpeggios that span an enormous tonal range.
