Maqamat
The Maqamat form the basis of traditional Arabic Music Theory.
There are 7, (sometimes 8) basic maqams, that have subdivisions and breakdowns based on pitch intonation and rhythm.
The eight maqams,(الصبا, النهاوند, العجم, البيات, السيكاه, الحجاز, الرست, الكرد) are combined in the memetic صنع بسحرك.
