There is a temporal difference between "harmonic" and "melodic".
Harmonic, (sounds played at the same time) yes, but melodic (in a sequence)
There was some interesting research done in the late 70's by Clarke and Voss
on correlated fractal noises mapped into music. Sequences with no
correlations (noises with 1/f^0 spectral power) produce unitellegible
melodies, those with 1/f^2 (1D Brownian motion) produce "boring" melodies
that wonder up and down, but those with 1/f spectrum are the most interesting
ones, which tested listeners tended to identify with "music".

The problem, here though is that mapping symbolic sequences (symbols are not
quantities) to frequencies (which are quantities) is completely arbitrary.
(I.e. what is the logic to map certain symbol to a particular frequency?).
Mappings done this way (with an arbitrary look up table) introduce
correlations and anti-correlations in the new sequence that do not exist in
the original data.
