Acemli Rast ("Rast with Acem") is the implementation of the descending version of the Rast scale in Turkish makam music. It is in 53 Tone Equal Temperament.
Components | Note | Western Note | Steps to following note | Cents from Durak note | Function |
---|---|---|---|---|---|
Rast pentachord | Rast | G | T (9) | 0 | Durak |
Dügâh | A | K (8) | 203.77 | ||
Segâh | B![]() |
S (5) | 384.91 | ||
Çargah | C | T (9) | 498.11 | ||

Hüseyni/Hisar | E | B (4) | 905.66 | ||
Acem | F | T (9) | 996.23 | The Yeden of this scale is Irak (F#), which is not octave equivalent with Acem. | |

Comparison with Western scales
Since the makam is based on 53-TET, it is impossible to directly tie it to 12-TET Western scales. However, using the 48-TET model, while worse than many other models in approximation,[2] allows for such comparisons.[3]
The approximation of Acemli Rast within 48-TET would be: Mixolydian (3)[4]
