Practice with a song you already have
Open a local audio file, loop a difficult section, and see your live pitch. Or try our guided three-note exercise for target-note feedback.
Sing with your audioHear the shape
Listen to an original three-note phrase. Move it up or down until it feels comfortable.
See where you land
Sing on your own. The line shows the pitch we could estimate, alongside the target.
Give it another go
Try one specific adjustment. Compare the next attempt without chasing a karaoke score.
OUR FIRST NOTES
A practice experiment, with room to grow.
This is an early prototype, not a proven singing course. It estimates pitch, not how good your voice sounds. You can play local audio privately or try our original exercise. Song-specific scoring is not available for local tracks. We’re learning whether this feedback is useful to adults in Korea and Japan.
YOUR NEXT SONG
Which song do you want to sing?
Pick a YouTube video or Spotify track and tell us the part that gets you stuck. Your requests will help us choose what to build next.
Song requests are research, not automatic song analysis. You can sing with a local audio file today. Matching its melody automatically is not available yet.
