When searching for Arabic music I noticed that there is no grand staff, just the treble clef. I am searching in the internet as to why this is the case. The explanation is that Western music relies on harmony (a couple of notes played together) while Arabic music relies mainly on melody (notes played one after another). My question is :
Can we transform any harmonic music to melody?
If the above is not always true, is there a site just for melodic music sheet?
