I for one have a strange sensation with the "melody" samples you and William provided. It reminds me the eerie disattached sensation you sometimes have picking up stuff with a numb hand. I listen to it, can hear all the pitches (surprising, because I know my ears are in a bad state), but it's almost as if the musical part of my brain switches off. There is no instant recognition of the melody, but only an analytical deduction afterwards. I cannot tell if it was out of tune or not. It feels out of tune and I don't like listening to it, but again the analytical half of my brain tells me it probably is in tune. I havent tried yet, but I think I'd have a lot of trouble reproducing the right pitches in a "normal" octave. Of course, if you do this with complex waveforms, you will start to get difference tones below 5000 Hz, and the whole point of the experiment was to see wether people can hear *melody* when all the aural information is above 5000 Hz. _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
