Tonemap Tuner

See your intonation tendencies over time! Tonemap listens and gives you visual feedback on each note you play, so whole passages become visible at a glance.

Tonemap is a real-time intonation visualizer for musicians. Instead of watching a needle one note at a time, you see your playing painted onto a color-coded grid: green when you're in tune, warmer when you're sharp, cooler when you're flat. Play a scale, a passage, or a whole etude, then look up and see exactly which notes need work.

Built by a professional orchestral violinist for daily practice. Trusted by professionals and beginning students alike!

THE GRID

• Every pitch gets its own cell, arranged in octave rows
• Colors show your average intonation on each note, not just an oscilloscope frantically saying you're sharp or flat
• Double-tap to clear and start fresh

NOTE VIEW

• Your playing drawn as a timeline: balloons show each note's average intonation, ribbons reveal vibrato and drift within a single note
• Scroll back through up to 20 minutes of playing

MADE FOR REAL PRACTICE

• Performance pitch: set A4 anywhere from 100–1000 Hz (440, 441, 415, etc.)
• Transposition for Bb, Eb, F and other instruments - see YOUR written notes
• Stretch tuning options for better resonance on acoustic instruments.
• Customizable colors, light and dark themes, and mini-UI to maximize screen space.
• Automatic gain control and adjustable background noise reduction
• No account, no ads, and audio never leaves your device

TONEMAP PRO (optional subscription)

Tonemap began as the open-source web app tonemap.live and is developed by Jeremy Black, Principal Second Violin of the Pittsburgh Symphony Orchestra and Concertmaster of the Grant Park Symphony Orchestra.
