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 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) - 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 and is developed by Jeremy Black, Principal Second Violin of the Pittsburgh Symphony Orchestra and Concertmaster of the Grant Park Symphony Orchestra.
