It is very difficult to find resources for learning Arabic Maqams in English. That's why, I decided to make a simple lesson of the scales from where I came from.
First, Maqams in the Arab Region are mainly used for 2 things:
1. Religious Islamic hymns
2. Old Arabic songs from the 60s until 90s, and also used until now.
Arabic Maqams are usually played with middle eastern / Turkish instruments such as: oud, buzuk etc... Those instruments have quarter-tone fret system. Of course additionally to the known half-tone and full-tone system. Fortunately, a not bad number of Maqams don't use quarter-tones.
Even though you can establish a quarter-tone sound on guitar by bending the string up, It still doesn't sound good as it sounds on typical Middle Eastern instruments. In this lesson, I am gonna put only Maqams that don't have a quarter-tone.
It worth mentioning that a good number of free quarter-tone Maqams can be equivalent to known scales/modes.
1. Hijaz Kar Maqam
Hijaz Kar Maqam has these intervals from the major scale: 1 b2 3 4 5 b6 7.
It is usually played in C: C Db E F G Ab B C.
When the Maqam is played in G, it is called Shadd Araban.
Shadd Araban Maqam: G Ab B C D Eb F# G.
In other words, Shadd Araban is a transposed version of Hijaz Kar, starting on G.
When the Maqam is played in D, it is called Shahnaz.
Shahnaz Maqam: D Eb F# G A Bb C# D.
When it is played in A, it is called Suzidil.
Suzidil Maqam: A Bb C# D E F G# A.
2. Ajam Maqam (Major Scale)
The Ajam Maqam has the same intervals of the major scale (Ionian Mode).
Bb is the most common Ajam Maqam in the Middle Eastern music.
Bb Ajam Maqam: Bb C D Eb F G A Bb.
The Ajam Maqam sounds western to the ear. That's why, it is called Ajam, which means someone who can't understand Arabic (foreigner).
Shawq Faza is a Maqam from the Ajam Maqam family.
Shawq Faza has these intervals: 1 2 3 4 5 b6 7.
It is usually played in Bb: Bb C D Eb F Gb A Bb.
3. Nahawand Maqam
One of the main middle eastern Maqams that is usually played in C.
Nahawand Maqam has two types:
The first one is called Nahawand Hijaz which is equivalent to the harmonic minor scale.
Nahawand Hijaz has these intervals from the major scale: 1 2 b3 4 5 b6 7.

The second one is called Nahawand Kurd Which is equivalent to the natural minor scale.
Nahwand Kurd has these intervals: 1 2 b3 4 5 b6 b7.

When the Nahawand Hijaz is played in G, it is called Sultani Yakah.
