Hi,
in terms of a musical composition:
- yes, the fundamental frequencies of the music itself, are multiples of the base frequency
-furthermore, the goal was to merge the the principles of brainwave entrainment and music, and to write music around 8 Hz monaural beats (monaural beats carrier frequency 128 Hz - C2), difficoult for me, if you consider that C2 is always there and it is appropriate to always find assonant harmonies. - where, for tecnical reasons (harmonic content or mixing problems in “Moonlight Sonata” and “The Lake”) I was not able to embed the 8 Hz monaural beats in the music, tempo division, tuning and amplitude modulations are always there screaming “8 Hz! 8 Hz!”
Thank you Early21 for your interest in these theoretical/tecnical considerations; you made me think to add these notes in the informations of the videos.
