I Played Piano at 429 Hz and Measured My Heart – Here's What Happened

In my previous video, I measured what happened to my heart rate while LISTENING to music at 429 Hz. This time, I wanted to know: what happens when I PLAY a live instrument tuned to 429 Hz? Spoiler: I was nervous. Really nervous. My HRV started at 8 – that's bad. But then something interesting happened... 🎹 Piano: Bechstein, tuned to 429 Hz 🎵 Song: Tom Waits – Falling Down 📊 HRV System: reviQuant ━━━━━━━━━━━━━━━━━━━ ⏱️ TIMESTAMPS: 0:00 – Intro 0:17 – Title 0:23 – HRV Baseline (nervous!) 0:30 – Playing begins 1:02 – Watch the HRV change 2:01 – Credits ━━━━━━━━━━━━━━━━━━━
