TeraMuse · Adaptive music for movement
Cadence-synchronized music for runs across distances, paces, and terrains.
What works for the runner next to you on the trail might actively slow you down — and this isn't motivational cliché, it's a genuine finding. Researchers including Cassidy and MacDonald have documented consistent individual differences in how people respond to music during physical exertion: extraverts tend to benefit more from high-arousal, beat-forward tracks, while introverts can experience the same music as cognitively crowding rather than propulsive. If you've ever found a playlist that everyone else loves and felt oddly drained by it, that's a plausible explanation. Your running music isn't just a tempo question — it's a signal-tolerance question, and getting it right means knowing your own threshold, not borrowing someone else's.
Cadence-synchronized music for runs across distances, paces, and terrains.
Music responds to a live signal in real time — building layers as your work or movement intensifies, easing back when you pause.
A real library across ambient, electronic, classical, lo-fi, neoclassical and beyond.
Running and music have an unusually well-studied relationship. Karageorghis et al. have shown across dozens of studies that tempo-synchronized music reduces perceived exertion at submaximal intensities — meaning the same pace feels easier with music that matches your cadence. The right BPM depends on your stride: easy runs cluster around 150–165 BPM, tempo work around 165–180, intervals 180+. Adaptive music that locks to your live cadence rather than requiring you to match a fixed playlist removes the friction of "this song is the wrong tempo."
For movement
Music that builds intensity as your effort builds and eases when you recover — synchronized to your live cadence, heart rate, or GPS speed.
Coming on iOS →It depends on intensity. Easy running typically benefits from music in the 110–140 BPM range; harder efforts pull toward 160–180+. Adaptive music removes the "this song is the wrong tempo" friction by synchronizing to your live cadence rather than requiring you to match a fixed playlist.
Yes, there's a free download for desktop. Paid plans unlock the full library and the Studio. The iOS app will be free for the launch period.
