Focused feedback

Your voice, with useful context.

Enough detail to investigate a phrase—without turning practice into a music-theory cockpit.

01

Live pitch mirror

Watch estimated notes, cents, and connected pitch shapes appear as you sing—then tap or scrub a note for a closer look.

02

Range-aware references

Set a comfortable practice range and Vocal Light places reference notes and chord voicings in a register that fits it.

03

Keys, notes, and chords

Choose a key, practice chromatically, or sound key notes and diatonic major or minor chords from one focused surface.

04

Solo or Guitar / Piano

Use Solo for a single voice, or try accompaniment-aware practice when singing near an acoustic guitar or piano.

Practice, then inspect

A pitch timeline you can touch.

Vocal Light groups estimated samples into readable note shapes. The main cents value gives you a fast center; one-finger scrubbing reveals individual samples when you want more detail.

Private by design

Your practice stays on your device.

Practice aid, not medical care.

Vocal Light provides estimates for general singing practice. It is not a medical device, professional vocal assessment, source-separation guarantee, or hearing-protection system. Practice comfortably and stop for pain, strain, dizziness, or hearing discomfort.
