Algerian Scales

The Algerian Scale has eight notes and the easiest way to memorize them are by the intervals. The first thing that you should give attention to in the Algerian scales is the three semi-steps that follow in sequence from note four to seven. In total, the scale has four halftones (see “Formula” below).

This scale is for anyody who likes music from the Middle East or just want to try something exotic. Additionally, there is an extendend version of this scale, which is presented below the pictures.
