Actually, it's www.wonderlandinorbit.com/projects/lullaby/ BTW, if you type it with the http part included, those viewing it in the most common browsers can click on in directly as a link rather than copying and pasting it into the browser's location thingy; like so: http://www.wonderlandinorbit.com/projects/lullaby/ > It seems that by taking steps of fourths and fifths, from a given pitch, > all "harmonics" (ghosttones?) can be mapped in a continuous series. You're returning to an ambiguous use of the word "harmonics". Please utilize these defined terms instead: Partials Harmonic Partials Inharmonic Partials Flageolet tones Ghosttones (I can accept this term since you have defined it) Complex Tones Simple Tones Since you wrote **"harmonics" (ghosttones?)**, I'll proceed with the assumption that you're talking about the tones you get when you lightly touch a string in various places and pluck it. I'll also give you the benefit of the doubt and assume that you're talking about the lowest audible simple tone (sine wave) for each ghosttone, and not the complete timbre of each ghosttone with its many partials. You're saying that the various tones you get by lightly touching an open string in various places form a continuous series separated by intervals of fourths and fifths. I doubt that this is so. Please write out this series of fourths and fifths (in cents, or Hz, or multiplication factors of the original open string frequency) along with a corresponding list of places on the string you'll have to touch in order to produce each of the pitches in that series of fourths and fifths (in inches from bridge or nut, or portion of string length, or some other measure). Please explain why some positions in the series of fourths and fifths are skipped (do not have a corresponding touch position), if any. I'm assuming the initial pitch at the beginning of the series of is the untouched, open string. Please explain if this is different. I've saved the rest of your message; let's discuss this much first.
