I certainly don't see why it shouldn't. I've always had the intuition that because the physical realm is primarily constituted of energy, propagated in waveforms and sound, including musical tones, on a different scale, are similar; I consider that tones in various harmonic combinations can indeed be beneficial. Having downloaded a freeware sound generator, I've created and burned onto cd's several harmonic combinations primarily in the pentatonic scale, as that specifically is very beneficial in my case.
