E Lydian Scale: Notes, Chords, and How to Play It

The E Lydian scale is a powerhouse for electric guitar, where the open low E string provides a thundering drone and the ♯4 (A♯) adds a soaring, luminous quality that standard E major lacks. E Lydian is the fourth mode of B major, meaning it contains exactly the same notes but treats E as the tonal centre. The result is a sound that hovers and floats — brighter than major, with an ethereal shimmer that guitar virtuosos like Joe Satriani and Steve Vai have made their signature.

Notes of the E Lydian Scale

The E Lydian scale contains seven notes:

E – F♯ – G♯ – A♯ – B – C♯ – D♯

It follows the Lydian interval pattern — W – W – W – H – W – W – H — which differs from the standard major scale by just one step: the distance between the 3rd and 4th degrees is a whole step rather than a half step, producing the ♯4.

Compare this to E major (E – F♯ – G♯ – A – B – C♯ – D♯): the only difference is A♯ instead of A♮. That single raised note — the ♯4 — lifts the scale above standard major, giving it an ethereal, open-sky quality.

Parent Major Scale

E Lydian is the fourth mode of B major. This means it shares every note with B major but starts and resolves on E. Understanding this relationship makes it easy to find Lydian scales across the keyboard or fretboard: simply play a major scale and start on its fourth degree.

E Lydian on Piano

E Lydian uses five black keys — F♯, G♯, A♯, C♯, and D♯. If you already know E major, the only adjustment is raising A to A♯. The scale sits comfortably under the hands, with the numerous black keys creating a natural hand shape.

Right hand fingering (ascending): 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 (thumb crosses under after G♯, then fingers walk up from A♯ to E)

Left hand fingering (ascending): 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 (after the thumb plays B, the third finger crosses over to C♯)

Focus on emphasising the root note E and letting the A♯ ring out clearly — that raised fourth is what tells the ear “this is Lydian, not major.”

E Lydian on Guitar

On guitar, E Lydian is arguably the most natural Lydian key. The open low E and high E strings provide powerful root drones, and the scale falls comfortably under the fingers in open position.

Open/first position (low to high):

The open E strings provide an excellent drone while exploring the scale higher up. This is the key Joe Satriani uses for many of his Lydian compositions. Use the guitar fretboard view in the Interactive Chord Finder to see all positions at once.

Diatonic Chords in E Lydian

Building triads on each degree of the E Lydian scale produces a chord family that differs noticeably from standard major. The most striking difference is the II chord — a major triad built on F♯ — which does not appear as a major chord in the key of E major. This major II chord is the harmonic signature of the Lydian mode.

Notice the pattern: major – major – minor – diminished – major – minor – minor. The diminished chord falls on the ♯4 degree (A♯), and the presence of two major chords at the start (I and II) gives Lydian progressions their characteristic brightness.

Seventh Chords

Adding a fourth note to each triad creates seventh chords with rich, colourful harmonic possibilities:

The Imaj7 chord (Emaj7) is particularly lush in Lydian context, and the II7 (F♯7) creates a dreamy, unresolved pull that is central to the Lydian sound. For more on seventh chords, see Seventh Chords: The Complete Guide.

Common Chord Progressions in E Lydian

Lydian progressions tend to hover and float rather than drive toward resolution. The most iconic Lydian sound is the simple oscillation between I and II.

The key to maintaining the Lydian sound is to keep returning to the I chord and to feature the II chord prominently. If you lean too heavily on the V chord (B), the ear may reinterpret the tonality as B major.

The Lydian Sound in Music

The Lydian mode is a favourite of film composers and guitarists seeking a sound that is brighter than major — luminous, floating, and full of wonder.

• Joe Satriani — “Flying in a Blue Dream” and countless other instrumentals are built on E Lydian, making it his signature sound
• Steve Vai — “The Riddle” and “For the Love of God” feature extended Lydian passages
• “E.T.” flying theme — John Williams uses Lydian to capture the magic of flight and wonder
• “The Simpsons” theme — Danny Elfman’s quirky main theme sits firmly in Lydian territory
• Progressive rock — bands like Dream Theater use E Lydian for soaring, transcendent passages

The ♯4 is what creates the “lift” — it removes the gravitational pull of the natural 4th degree, leaving the scale feeling weightless and unresolved in the most beautiful way.

Comparison with E Major

Since Lydian is so close to major, it helps to see them side by side:

The single raised note changes the entire mood. E major sounds settled and resolved; E Lydian sounds open and aspirational. In practice, many guitarists move between the two by alternating A♮ and A♯ within a piece, creating moments of Lydian brightness against a major backdrop.

Related Scales and Modes

E Lydian belongs to the B major family of modes. All seven modes share the same notes but start on different degrees:

Practice Tips

Emphasise the ♯4. When practising E Lydian, linger on the A♯. Play E to A♯ and back — that tritone interval is the heart of the Lydian sound. Train your ear to recognise it instantly.

Vamp on I–II. Play E and F♯ major chords back and forth while improvising melodies from the scale. This simple two-chord vamp is the quickest way to internalise the Lydian feel.

Compare with E major. Play E major ascending, then immediately play E Lydian. The only note that changes is A to A♯, but notice how dramatically the mood shifts. This comparison builds your ear for modal colour.

Use over major seventh chords. In a jazz context, Lydian is the go-to scale for major seventh chords. Practise playing E Lydian over an Emaj7 vamp to hear how the ♯4 adds colour without clashing.

Practise with a drone. Play or sustain a low E note while running through the scale. The drone anchors E as the tonal centre and prevents your ear from slipping back to hearing B major.

Try It Yourself

Open the Interactive Chord Finder, select E as the root and Lydian as the scale. You will see every note highlighted on the piano keyboard or guitar fretboard, the step pattern visualised as intervals, and all diatonic chords laid out in a table — ready to play and explore.
