Dorian bebop scale | Guitar fretboard diagrams and formula
The dorian bebop scale (or minor bebop scale) is an eight notes scale (octatonic). It is commonly used in bebop. This scale like all the octatonic scales (except the symmetric scales) contains a chromaticism, an additional note between the minor third (b3) and the fourth (4). The dorian bebop scale is the same scale as the dorian mode including a major third (3) between the minor third (b3) and the fourth (4th).
There are two versions of this scale, one with a passing tone (3) between the b3 and the 4th and one with a passing tone (7) between the b7 and the root, this one has the same intervals as the dominant bebop scale. At this point only the first version is shown in this lesson.
The dorian bebop scale is a minor type scale so it can be used over minor 7th chords. It's an interesting alternative for those who want to increase their musical language. Most of the time jazz guitar players used the dorian mode, minor pentatonic scales or some arpeggios to play over a minor seventh chord. Playing the dorian bebop scale open up new horizons.
We can see in the example below that the D bebop dorian scale contains a minor third (F), a chromatic passing tone (F#) and a minor seventh (C).

Dorian bebop scale | Guitar position and fingerings # 1
Here is a first dorian bebop fretboard guitar diagram and fingerings.
To hear this scale correctly, it is recommended to play these patterns by starting with the root (R) and to play them by ascending and descending movements.
To play the A dorian bebop scale starting with the lower root you must put your first finger on the sixth string at the fifth fret.
Playing the corresponding chord after or before these patterns is a nice way to bring scales and chords together.
Be sure to play these patterns in twelve keys.
Pattern 1 w/intervals. Roots on the sixth, fourth and first string.
Pattern 1 w/fingerings (suggested)
Dorian bebop scale | Guitar position and fingerings # 2
This second pattern has its roots (R) on the fifth and the third string.
For example, to play the D dorian bebop scale using these diagrams starting with the lowest root you have to put your first finger on the fifth string at the fifth fret.
Once again, be sure to play this pattern in twelve keys, ascending and descending.
Pattern 2 w/intervals. Roots on the fifth and the third string.

Dorian bebop scale | Guitar position and fingerings # 3

Pattern 3 w/intervals. Roots on the sixth, the third and the first string.
