The project
Introduce the Arabic scale through appropriate notation, and ask the
pupils to play the scale on any instrument. Singing it may be difficult
due to the Augmented 2nds in the melody.
The Arabic Scale

Divide pupils up into groups of 3 or 4. One pupil can play a drone consisting of the C and G played to the rajaz rhythm
Rajaz rhythm

Each pupil should now make up a short phrase using the notes of
the scale. Once they have all made up a melody, they can collaborate their
ideas so that one phrase answers another. The melodies can be repeated
as ostinatos if necessary. There are many possible variations to this idea.
This is just one idea!
