Moss is a musical language. Words are recognized in four elementary melodic distinctions: long or short, high or low, near or far, and continuous or separate. It has a tiny lexicon that ranges over the combinatoric space produced by these basic distinctions, so that no melodic rudiments are excluded. At the same time, Moss abandons pitch, pacing, inflection, and other aspects of melody to free variation, where they're magnetized by the desire of the speaker.
Moss is a pidgin language: a makeshift, non-standardized contact language. With only 120 words and a few grammatical rules of thumb, it is very easy to learn. When in doubt, you can fall back on patterns and idioms that are comfortable to you. If you’re familiar with European notation, then the heuristic notation on this site will feel natural to you, but it is just a convenience - this website is designed so that you can learn by listening and imitating, just like a normal language.
Listen to any unfamiliar language, and you will hear a grasp of sound which is vast and intricate despite being largely unconscious. Moss provides this grasp with a musical handle.
