IMO you can't do iconic "desert" music without the "Oud" sound (basically an arabic lute that's also played in parts of africa).
On that note, if possible try to use quarter tones and the traditional maqam system. You'll need to use 24-TET to do this, and it isn't as hard to implement as other alternative tuning systems.
Here's the second movement for my first microtonal trio for guitar, bass guitar, and keyboard tuned to the 32-note Harmonic Series scale. Please leave comments, criticisms, feedback, as even Monarcheon's feedback on the first movement helped a lot. Hope you enjoy it!
I have no idea what any of the terms used by both you and Monarcheon mean Luis but I have enjoyed listening to this as this is my third time listening and it sounds amazing brother.
Piano stuff aren't truly my thing, I'm very heavy into large ensembles which is why majority of my stuff are in that section but I enjoy the way your left and right hands play off of each other. The sound itself is incredibly smooth and it is a real joy to listen to repeatedly. Amazing work.
A suite made up of sketches 58, 62, and 78. I like this better than the first, personally, since I actually studied this type of music before these sketches, instead of mindlessly writing what I thought this type of music was. Enjoy!
