Tonemap Tuner
Visual intonation practice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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)
- 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.
