The Lydian dominant scale on bass:
notes, formula and position
The Lydian dominant scale has 7 notes: 1 2 3 ♯4 5 6 ♭7. In A, that gives A, B, C♯, D♯, E, F♯ and G. The 4th mode of melodic minor: Mixolydian with an augmented fourth. It is the scale of the 7♯11 chord, very common in jazz and fusion.
Also called: Lydian ♭7, acoustic scale, overtone scale, mode IV of melodic minor.
Formula and notes
1 2 3 ♯4 5 6 ♭7
The steps between the notes, from the root to the octave: whole step – whole step – whole step – half step – whole step – half step – whole step. In A:

|---|---|---|---|
| 1 | root | A | 0 |
| 2 | major second | B | 2 |
| 3 | major third | C♯ | 4 |
| ♯4 | augmented fourth | D♯ | 6 |

| ♭7 | minor seventh | G | 10 |
Where the Lydian dominant scale comes from
It is the 4th mode of melodic minor: you play the notes of melodic minor starting from its 4th degree. The Lydian dominant scale in A therefore has the same notes as E melodic minor. What changes is the home note: the root A, the note your line keeps coming back to.
One position on the neck
The Lydian dominant scale in A, in the 5th-fret position: one finger per fret, from the 4th to the 8th fret, on all four strings. The numbers are the degrees; the root is in gold.
The same position as bass tab (fret by fret, from the low E string to the G string):
G|-4--6--8-| D|-4--5--7-| A|-4--6--7-| E|-5--7-|
For another key, move the whole shape: the root on the E string sets the key (3rd fret for G, 8th fret for C).
