The planet Pitch is covered in deep warm oceans. It is inhabited with intelligent starfish called Pitchians who wander about the dark depths of their home ocean, feeding on their world’s version of clams and oysters. Pitchians have no sense of sight and no sense of touch, just smell/taste and hearing with a form of echolocation. The Pitchian’s senses do not work at all like ours. If we could get into a Pitchian mind, we would hear nothing but sounds of different pitches and tones and volumes. There would be no sense of space like humans have. Larger objects produce louder echos, softer objects produce fuzzier echos, moving objects produce echoes with a shift and/or a doppler effect, but to the Pitchian, this is just a difference in quality of sound, it does not give a spatial intuition. It’s sort of like when a human hears two notes played on the same guitar at the same time. We do not sense two different sounds, but one sound with a special quality depending how the two notes harmonize.
