About

Notespawn

Features
Read full description

Notespawn generates unlimited piano sight-reading exercises that actually sound like music - not random notes on a staff. Most sight-reading apps hand you a fixed library that runs out, or generate note-soup that no composer would write. Notespawn builds every exercise from real harmonic progressions first, then shapes the melody and rhythm around them. The result reads like repertoire: phrases resolve, cadences land, and your eyes learn patterns that show up in actual music. DIAL IN YOUR LEVEL - Difficulty levels from beginner to advanced - Single line, hands together, or chord textures on the grand staff - Choose key signatures, time signatures, and tempo - Modulation control for advanced practice PRACTICE SMARTER - Every exercise is brand new, so you can never memorize your way out of reading - Note-by-note practice mode listens to your instrument through the microphone and checks what you play, right at the piano - no MIDI cable required - Built-in metronome and playback so you can hear the exercise and check yourself - Seeded generation: share a seed and any two players get the identical exercise, perfect for teachers assigning the same page to a whole studio - Export to PDF for printing or MIDI for your favorite apps BUILT FOR PIANISTS Designed around how piano reading actually works: two staves, two hands, voicings that fit under real fingers. No account. No ads. No tracking. Open the app and read.
