The scale displayed with its numeric formula, intervals and scale degrees.

Formula Notes Intervals Degrees
1 Ab Unison Tonic
2 Bb Major second Supertonic
b3 Cb Minor third Mediant
4 Db Perfect fourth Subdominant
5 Eb Perfect fifth Dominant
6 F Sixth Submediant
b7 Gb Minor seventh Subtonic

The third degree is written as Cb, which is the same as B. A practice in a scale notation is to not include the same letter twice, if it can be avoided.

The A flat Dorian scale consists of seven notes. These can be described as steps on the guitar fingerboard according to the following formula: whole, half, whole, whole, whole, half and whole from the first note to the same in the next octave.
The A flat Dorian is the second mode of the Gb Major Scale. It contains exactly the same notes, but starts on another note. Since Dorian has a minor scale quality it can also be seen as a mode of the Eb Minor.
The scale is otherwise most related to the Ab Natural Minor and Ab Melodic Minor scales, which differ with just one note in both cases.

This scale is typically played over a minor seventh chord (primarily Abm7 in this case) and is used in styles such as jazz and blues.
One way to learn this scale is to observe the minor 7th chord shapes that it is built around. For example, the Abm7 barre chord with the root on the 6th string within the scale in 4th position. Another way is to think of it as the Ab Minor scale with a raised sixth.

Chords that are related to this scale are the following:

Abm7, Abm9, Abm11
Bbm7
Bmaj7, Bmaj9
Db7, Db9, Db11, Db13
Ebm7, Ebm9, Ebm11
Fm7b5
Gbmaj7, Gbmaj9, Gbmaj13

The tones in these chords correspond to the tones of the Ab Dorian scale (triads have been excluded).

Related to this scale are Dorian b2 and Dorian #4, being the 2nd mode of the Melodic Minor and the 4th mode of the Harmonic Minor.

The Ab Dorian b2 scale, also known as Ab Phrygian #6 scale, is identical to the Ab Dorian except for the minor second. It can be displayed as follows:

Formula Notes Intervals Degrees
1 Ab Unison Tonic
b2 Bbb Minor second Supertonic
b3 Cb Minor third Mediant
4 Db Perfect fourth Subdominant
5 Eb Perfect fifth Dominant
6 F Sixth Submediant
b7 Gb Minor seventh Subtonic

The Ab Dorian b2 contains the same notes as the Gb Melodic Minor Scale, but starts on another note.

The Ab Dorian #4 scale is identical to the Ab Dorian except for the augmented fourth. It can be displayed as follows:

Formula Notes Intervals Degrees
1 Ab Unison Tonic
2 Bb Major second Supertonic
b3 Cb Minor third Mediant
#4 D Augmented fourth Subdominant
5 Eb Perfect fifth Dominant
6 F Sixth Submediant
b7 Gb Minor seventh Subtonic

The Ab Dorian #4 contains the same notes as the Eb Harmonic Minor Scale, but starts on another note.
