Quite interesting to let Tunelab listen to this. To my ear, I was certain I was hearing some strong, distinct partials. Tunelab shows the one large spike slowly increasing, accompanied by at least nine visible partials. At the lower end, the partials are certainly more distinctly heard than the fundamental, despite their volume being so much lower. The partials are mathematically placed but are not based on multiples of 2, 3, 4, etc as we are accustomed to with musical tones. See attached screenshot, taken when the tone is at 60hz.
