A Lydian in 7-string — Notes and Intervals
The A Lydian scale is the fourth mode of the major scale and arguably the brightest sound in music theory. On Guitar, the notes are A, B, C#, D#, E, F#, G#. It is known for its ethereal, dreamlike, and cinematic quality. Because it avoids the pull of the perfect fourth, it is a favorite for film composers wanting to evoke a sense of wonder or otherworldly space. The diatonic chords of A Lydian are AMaj7, B7, C#m7, D#m7b5, EMaj7, F#m7, G#m7. Commonly used in Film Scores, Progressive Rock, Fusion, Ambient, Dream Pop. Notable players include Joe Satriani, Steve Vai, John Williams, Hans Zimmer. Use over Maj7#11, Maj9 chords. Ideal for non-resolving major passages. Avoid when the music needs to feel grounded or resolved.

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
The #4 (tritone from root) eliminates the gravitational pull of the perfect 4th, creating a sensation of weightless suspension — the reason film composers use it for 'wonder' and 'awe'.
