Piano Visualizer is a free browser-based MIDI piano visualisation tool created by Howard Wilson. It allows users to connect compatible MIDI keyboards and view note activity in real time on an interactive piano keyboard and grand staff notation display.
Designed for music teachers, students, performers and composers, Piano Visualizer helps bridge the gap between keyboard performance, music theory and notation learning.
Automatically detects connected MIDI devices and displays notes as they are played.
Notes appear instantly on treble and bass staves, helping users connect notation with keyboard performance.
Supports major key signatures and correctly displays accidentals and natural signs.
Play notes directly in the browser and receive immediate visual feedback.
Piano Visualizer helps students understand the relationship between written notation and keyboard performance. By displaying notes on both the piano keyboard and grand staff simultaneously, learners can develop stronger music reading skills and theoretical understanding.
It can also be used to support lessons on intervals, scales, harmony, chords, key signatures and general musicianship.
Planned features include chord recognition, scale visualisation, sight reading exercises, interval training and additional resources for music educators and students.
