I listened to your Arabic dreaming tune. While it's interesting, you're not playing arabic scales at all.
One of the most basic arabic scales is the Hijaz Maqum C - Db - E - F - G - Ab - Bb - C this scale is widely used and one that you can hear Joe Satriani use to great effect.
May I suggest a look into the world of Maqams if you really want to get into this stuff.
Arabic maqams are based on a musical scale of 7 notes that repeats at the octave. Some maqams have 2 or more alternative scales (e.g. Rast, Nahawand and Hijaz). Maqam scales in traditional Arabic music are microtonal, not based on a twelve-tone equal-tempered musical tuning system, as is the case in modern Western Music. Most maqam scales include a perfect fifth or a perfect fourth (or both), and all octaves are perfect. The remaining notes in a maqam scale may or may not exactly fall on semitones.
If you're going to start working on 24 note scales then you'll need a harp that is designed to do that....HEY I happen to be making those these days.
