B Enigmatic in 7-string — Notes and Intervals
The B Enigmatic scale was invented as a musical puzzle and famously used by Giuseppe Verdi. On Guitar, the notes are B, C, D#, F, G, A, A#. It has an unstable and surreal sound because it lacks the traditional fourth and fifth degrees, creating a gliding effect that challenges the listener's expectations. Commonly used in Classical, Experimental, Film Scores. Notable players include Giuseppe Verdi, Igor Stravinsky. Not chord-specific — this is a melodic scale for creating surreal, non-functional passages. Use over sustained pedal tones or atonal contexts.

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.
Notable artists: Dream Theater, Periphery, Animals as Leaders, Korn, Meshuggah
Best for: Progressive metal riffs, extended-range chord voicings, djent rhythms, and jazz fusion harmony
Musical Character
Invented as a musical puzzle — lacks the traditional 4th and 5th degrees, creating a gliding, rootless sensation. Verdi used it in his Ave Maria to challenge conventional harmony.
