Perfect Intonation is a new software tool for music professionals, educators, and students. It allows you to see the pitch you are singing or playing in real time. By comparing auditory and visual feedback, you can learn to sing target notes and songs faster and with greater accuracy.

Perfect Intonation is an excellent tool for voice and string musicians who want to improve their ability to discriminate pitch.

Perfect Intonation has a complete music display system, and supports the MusicXML universal file format.

You can load any MusicXML file — including your own compositions — into Perfect Intonation, and it will display each track on musical score. You can learn to sing or play any part by choosing different tracks within the song as your "target" track.

Many popular music software packages (including Finale and Sibelius) can export compositions in MusicXML format. For more information on MusicXML and products that support it, visit the MusicXML website

In addition to real-time pitch display, Perfect Intonation evaluates each performance and provides you with information regarding your pitch and timing accuracy and tightness of your tone for each target note. You can even calibrate the stringency of the evaluation to your skill level.
