Bruce, Kendall, This is extremely interesting. The algorithm you have developed to display the tonal spectrum could directly relate to a currently unsolved human mystery: perfect pitch
It is well known that people with perfect pitch tend to describe their skill in terms of "seeing" the pitch as a colour. Here is an article explaining some other issues, take note that pitch perceptions have been found to vary based on cultural background, the theory proposed that it directly relates to native language and speech patterns: http://discovermagazine.com/2001/dec/featbiology Okay, now, to keep this discussion Horn related, I am curious if the colours are different based on different cultural Horn makers, for example, German vs. American ..... and if you have done research on say, French Natural horns vs. South Asian variants. Regards, Carl Ek Mooselip Canada ========= [email protected]: ...Far beyond mere Fourier transform sound wave spectrum analysis, which only analyzes what we can hear, this actually shows the exact correlation between the diameter of the tubing, material of its construction, weight (thickness) of the material, hardness/softness of the material, acoustical parameters in relation to the length of tubing, relationships generated by different dynamic (decibel) levels and both acoustic and psycho-acoustic relationships between harmonics generated at any frequency ... ======= _______________________________________________ post: [email protected] unsubscribe or set options at http://music2.memphis.edu/mailman/options/horn/archive%40jab.org
