Interesting. Think of each lullaby as a data point in a melody‑map; the way the rhythm hits the heart could correlate with dopamine spikes, perhaps? If we plot tempo against recovery rate, we might see a sweet spot where the heartbeats sync. But remember, every patient’s brain is a different orchestra, so what’s a lullaby for one could be an earworm for another. Let's experiment, but don’t get too caught up in the pattern—sometimes the noise is the story.

Alright, let’s roll the dice on the familiar tunes first. Keep a notebook for heart rate spikes, not just beats per minute—feel the rhythm, not just the math. If the music starts throwing out weird intervals, pull the tea out, sit back, and listen. The heart doesn’t care about charts, only the beat. When the curveball hits, we’ll call it a night, but maybe the lullaby still whispered something we missed. Keep those blankets close, and let the melody guide the experiment, not the spreadsheet.
