The concept

Not another tuner.

A tuner tells you if the note is sharp or flat right now. Tonagi measures, tracks and shows how your intonation evolves over time — the difference between a mirror and a coach. For every musician — including singers.

Listen

The microphone analyses what you play or sing in real time, note by note.

Train

Reference sequences, routines guided phase by phase and a full metronome give your practice structure.

Improve

Every recording gets a score, a note-by-note profile and automatic observations.

The proof

Four takes of a G major scale.

Every take is scored from 0 to 100 — how long you stayed within ±10 cents, note by note. Watch the number climb between takes, and you know the practice worked.

The name

Why Tonagi?

Tonagi

Tone — The reference you hear.

Tonari 隣 — The partner always by your side.

Nagi 凪 — The sea falls still.

Tonagi is the partner playing the tone by your side, until the note settles.

Tonagi brings three ideas together. Tone is the pitch, the reference you hear. Tonari (Japanese, “by your side”) is the partner who’s always there — like a friend playing alongside you as you study. And Nagi (Japanese, 凪) is the moment the sea falls perfectly still.
