528 Hz ; the love frequency, is used as a binaural beat at the speed 10 Hz for this 528 Hz binaural meditation.

The 528 Hz Solfeggio frequencie is from an ancient scale; used in ancient music, chants and ceremonies. The Solfeggio tones were believed to enable spiritual blessings and transformation when played or sung in harmony.

According to Dr Len Horowitz and Dr Puleo; some genetic biochemists suggest frequency 528 Hz is the repair frequency for damaged DNA.

Regardless of ones individual beliefs, as each note has a different tuning from the conventional musical scale, these tones provide a new stimulus to the mind and physical system.
Its recently accepted by scientists; that by just providing the brain with new input alone, has many benefits; in relation to brain plasticity (keeping the mind young healthy and active). As the mind becomes healthy the physical body responds and also reaps its own reward.

Binaural Beats are a scientifically proven brain entrainment process that slowly started to gain recognition after an article called, Auditory Beats in the Brain, by Dr Gerald Oster, was published in the October 1973 edition of Scientific America.
Binaural beats work by sending two different Hz frequencies, to each ear via causing the left and right Brain hemispheres to work in unison to hear a phantom frequency or third tone, the centred Hz difference between the two tones. The Hz separations cerate a constant gentle beat and its timing and pulse match the Hz separation per second. The binaural beat process can be used to stimulate altered states of consciousness by selecting binaural beat patterns to mach a desired brainwave. After a few minuets of listening and calculating, the brain starts to mach this binaural beat; because of a process called frequency follow response. In reality a binaural beat is not heard as true sound in the headphone environment, it is more like a neurological signal perceived within the brain by both brain hemispheres working in unison.
The neural synchrony stimulated by binaural beats is a major aspect that assists the brain to function at a higher level. The brain continually forms new connections following new experiences. The quality and strength of neuronal connections can vary according to the input received by the brain. Binaural beats in the Alpha, Theta and Delta range provide a continuous relaxed input and promote healthy rewiring through its audio neurological signal calculation. These new audio experiences in the brain trigger a burst of new connections between neurons, and with repetition these new neural pathways become fit, just like going to a gym, and it is the fittest connections in our brains that survive. The binaural beat process is faster, easer and more than just meditation and after several weeks the brain becomes more lateralised and starts to form permanent relaxed memories in both hemispheres.
