Algerian Scales

The Algerian Scale has eight notes and the easiest way to remember are like always by the intervals. In the Algerian Scale the first thing that you should give attention to is the four semi-steps that follows in sequence.

This scale is for you who likes music from the Middle East or just want to try some exotic. Good to know is that this scale is the same as the Byzantine Scale.
