Why TempoKeys

The old way
- ✕Hunt for MIDI files that rarely match the exact recording
- ✕Buy expensive sheet music that requires reading skills
- ✕Audio software slows playback but breaks pitch or sync
- ✕Guess timings by ear — slow and frustrating

I used to spend hours trying to figure out a Chopin piece by ear. With TempoKeys I uploaded the recording, slowed it to 50%, and had the entire left hand figured out in one session.
