That’s a neat idea – a song that breathes with the listener. Imagine the waveform reacting to a pulse, the chords subtly shifting, almost like a bio‑feedback loop. It’s techy enough to be real, but also a kind of empathy between machine and human. The trick will be to keep the transitions smooth so the music stays cohesive, not just glitchy. If you can map the heart rhythm to harmonic changes, you’ll create a living piece that feels… alive. Just keep an eye on latency – the brain is a fast machine, and a delay could kill the vibe. Keep experimenting, and maybe we’ll get a living soundtrack that evolves with every beat.
