Elvish

Elvish is actually in the same family as dwarvish, sharing the same low tones with sharp consonants, but these roots are expressed quite differently. Elvish takes the sharp consonants to the extreme in the form of whistles and high clicks and the low tones dropping to practically white noise. Being able to effectively discern the language with only these sharp cracks has made elvish a very desirable language for scouting troops in militaries. 
The Elvish script reflects the spoken component, being defined by low squiggles with high, differently shaped peaks. This system is somewhere between cursive and binary.
