Deletion of Tristimulus timbre model

Comment: to the section Timbre#Harmonics. GScholar produces 10 hits for "Tristimulus timbre" and among those papers are only a small number of researchers. There don't seem to be enough in-depth independent sources to pass notability thresholds. But the model is real and has been used as a convenient low-dimensional representation of the harmonic aspects of a timbre, as in https://ccrma.stanford.edu/~jrobfox/fox_carlile_ICAD05.pdf SoniMime. Per , we prefer to preserve verifiable information through merging rather than deletion. I'd recommend merging a short description and a ref verifying to Timbre#Harmonics, which seems the best target given that we have no general article on timbre theory or modeling
