1) Sound → Brain Signals
When you hear a song, sound waves enter your ear and are converted into electrical signals. These travel to the auditory cortex, where pitch, rhythm, and harmony are decoded.

2) Rhythm Syncs Your Brain
Steady beats can encourage brainwave entrainment—your brain’s natural rhythms (alpha, theta, etc.) subtly synchronize with the music. This can promote focus, calm, or alertness depending on tempo and frequency patterns.

3) Dopamine = Pleasure & Motivation
Music you enjoy triggers dopamine release in reward pathways. That’s why a “brain song” can feel motivating, uplifting, or comforting—even before the chorus hits.

4) Emotions Get Involved
The limbic system (emotion center) reacts to melody and harmony. Minor keys may evoke sadness; major keys often feel brighter. Emotional engagement strengthens the effect.

5) Memory Boost
Music activates the hippocampus, linking sound with memories. This is why certain songs instantly bring back feelings, images, or focus states.

6) Stress Reduction
Slower tempos and smooth dynamics can lower cortisol (stress hormone), slowing heart rate and breathing—helpful for relaxation or sleep.
