Flashback by Calvin Harris

Upbeat tempo = typical for dance music

"'Flashback'represents a time before his 2014 health-related lifestyle change, showcasing a raw, high-energy, and slightly grittier electronic sound compared to his later productions."

How does sound actually influences brainwaves?

Arousal & attention (most important mechanism)

Sound affects the brain through attention and emotion, not by matching Hz.

Slow, soft, predictable sounds → lower arousal

Loud, fast, unpredictable sounds → higher arousal

Brain waves ≠ sound waves

Brain waves	Sound waves
Electrical activity	Mechanical air pressure
Measured in EEG	Measured in Hz via vibration
Broad, fuzzy ranges	Precise, exact frequencies

“But I feel different listening to 432 Hz music”

That can be real — just not mystical.

Slightly lower pitch feels warmer or softer

Slower, calmer arrangements often used with 432 Hz tracks
