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 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!
