G Lydian mode
Start on G and follow the step pattern W–W–W–H–W–W–H to build this scale: G – A – B – C♯ – D – E – F♯.
G Lydian mode notes and formula
The interval formula is 1–2–3–♯4–5–6–7, and the adjacent-note pattern is W–W–W–H–W–W–H. It is mode 4 of D major and therefore shares that collection of notes and its 2 sharps.
| Degree | Formula | Note | Semitones | Interval from root |
|---|---|---|---|---|
| 1 | 1 | G | 0 | Root |
| 2 | 2 | A | 2 | Major Second |
| 3 | 3 | B | 4 | Major Third |
| 4 | ♯4 | C♯ | 6 | Augmented Fourth |
| 5 | 5 | D | 7 | Perfect Fifth |
| 6 | 6 | E | 9 | Major Sixth |
| 7 | 7 | F♯ | 11 | Major Seventh |

G Lydian mode on piano
Use the keyboard diagram as a note map rather than treating it as a fixed fingering. Say each note name aloud, play one octave slowly, and keep the rhythm even before increasing speed.
Next, practice in groups of two, three, and four notes. Changing the accent pattern exposes uneven finger transitions that can be hidden when every note receives the same emphasis.
G Lydian mode on guitar
The diagram marks every scale tone in standard tuning from the open strings through fret 12. Darker circles are G roots. Learn one position first, then connect it horizontally along a single string.
Chords and harmonic use
Stack every other scale tone to build the diatonic triads and seventh chords below. The exact harmonic emphasis depends on style, but all listed notes come from this scale.
| Degree | Triad | Triad notes | Seventh chord | Seventh notes |
|---|---|---|---|---|
| I | G | G – B – D | Gmaj7 | G – B – D – F♯ |
| II | A | A – C♯ – E | A7 | A – C♯ – E – G |
| iii | Bm | B – D – F♯ | Bm7 | B – D – F♯ – A |
| iv° | C♯dim | C♯ – E – G | C♯m7b5 | C♯ – E – G – B |
| V | D | D – F♯ – A | Dmaj7 | D – F♯ – A – C♯ |
| vi | Em | E – G – B | Em7 | E – G – B – D |
| vii | F♯m | F♯ – A – C♯ | F♯m7 | F♯ – A – C♯ – E |
Sound, characteristic notes, and practice ideas
Lydian is a major mode with a raised fourth. The sharp fourth avoids the usual perfect-fourth pull and creates an open, floating color. The key to hearing the scale is not only playing all the notes in order; hold a G drone and deliberately land on the characteristic degree.
Sequence
Play 1–2–3, 2–3–4, 3–4–5, continuing through the scale and back down.
Intervals
Alternate the tonic with every other scale tone to memorize its interval sound.
Improvisation
Create a two-bar motif, repeat it, then change only the final note while keeping the rhythm.

Frequently asked questions
What notes are in the G Lydian mode?
The notes are G, A, B, C♯, D, E, F♯, returning to G at the octave.
What is the formula for G Lydian mode?
The scale-degree formula is 1–2–3–♯4–5–6–7. The step pattern is W–W–W–H–W–W–H.
How do you play the G Lydian mode on piano?
Play the highlighted keys in order: G – A – B – C♯ – D – E – F♯, then repeat G at the octave. Practice each hand separately before combining them.
How do you play it on guitar?
Use the fretboard diagram to locate every scale tone from the open strings through fret 12. Start and finish phrases on the darker G root markers so the tonal center remains clear.
What makes this scale sound different?
Its defining feature is the raised fourth. Emphasize that degree against a tonic drone to hear the scale identity.
