Tonemap Tuner

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 Jeremy Black, Principal Second Violin of the Pittsburgh Symphony Orchestra, and Concertmaster of the Grant Park Symphony Orchestra in Chicago. Tested and trusted by teachers and professional musicians around the world! 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 TEMPERAMENTS - Practice in just intonation, Pythagorean, meantone, Vallotti, Werckmeister III and more, or build your own Custom temperament - Every note's target, color and needle follow the temperament you choose - Set the Pitch Center to your key, with a Temperament Bar to switch temperament and key in one tap MADE FOR REAL PRACTICE - Performance pitch: set A4 anywhere from 100–1000 Hz (440, 441, 415, etc.) - Transposition for Bb, Eb, F and all other instruments - 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) - Quick Record: capture your practice, review at slow speeds with pitch-preserving playback, and export WAV - Hard Mode: the tightest in-tune window, for advanced intonation work - Supports ongoing development Tonemap began as the open-source web app tonemap.live.
