Intona is a practice tool for singers who want to work on pitch accuracy. You pick a short vocal exercise, sing along, and see in real time how close you are to the target pitch.
Built as a 6-week project for the KSInternship 2026.
Most "sing in tune" tools either (a) only tell you the note name, which hides the small pitch errors that actually matter for intonation, or (b) are built for karaoke rather than practice. Intona is closer to a tuner for your voice: a fast feedback loop and a clear visual signal of sharp / flat / in tune.
- Pick an exercise from a small fixed set (sustained note, simple interval, short melody)
- Real-time pitch detection from the microphone
- Live visual feedback: your pitch vs. the target pitch
- An end-of-exercise score (% time in tune, average deviation, etc)
out of scope:
- User accounts, login, cross-device sync
- Persistent history / long-term progress tracking
- Gamification (streaks, levels, badges)
