I suppose this is technically music related, but i'm not sure it fits anywhere else. While I have a rudimentary understanding of both physics as a whole and the physics of sound, i am by no means adept. So the general idea is to represent the sounds of the standard open strings of the bass (E,A,D,G) in tattoo form. My initial thought was to do this via an accurate representation of the sine wave of the notes...so basically the fundamental wave form. Upon further consideration, I realized this only represents part of what we hear, as i didn't take into account the harmonics of the struck note. Am I correct in saying that a more accurate portrayal would be a triangle wave? My second thought was based upon the synesthesia condition. To represent the different waves in corresponding colors. We all know that red has a long wavelength and indigo has a short wavelength. In my head i'd take the 44.1 hz E string to 441 Thz (i think) in a dark red and the subsequent higher strings in progressively cooler colors. Using the same multiplier to take sound waves to the visible light spectrum, the G string at 98 hz come out of the visible light spectrum entirely and into ultra violet. So while trying to stay as scientifically reasonably as possible and understanding that some artistic freedom is necessary, does anybody have any ideas on how to proceed. I know it's a tall order. Thanks TB.
