Tunebrush: Draw Music Maker

Draw a picture and hear it play. Tunebrush turns every stroke into music, then saves your drawing as a vertical music card video you can share. The first launch walks you through your first song in about 30 seconds: play the rainbow, draw a line, switch colors.

HOW IT WORKS
• The canvas is a grid: left to right is time, top to bottom is pitch.
• Draw with your finger. Each color is an instrument, and you hear a note the moment you touch a new row.
• Press play and your drawing is performed while ink blooms on every note.
• Line view is the default: your drawing stays as ink lines exactly as drawn, and ink drops bloom on the line where each note sounds. A button in the bottom toolbar, next to the eraser, switches to block view, which shows the note cells. Your music card video uses the same view.
• Pick a mood (Dreamy, Cozy or Moody) and a tempo to hear the same drawing in a different light.

SOUNDS GOOD ON PURPOSE
Each mood uses a fixed set of notes, so even a quick scribble stays in tune. When a chord gets crowded it is thinned out, and a vertical line is strummed from bottom to top instead of hitting all at once.

MUSIC CARDS
Tap Card, name your artwork and save a vertical video (720 × 1280, 10 to 15 seconds) of your drawing being played. Share it from the app or save it to your phone. Want only the sound? Export audio on its own.

YOUR ARTWORKS
Everything is saved automatically on your device. Start from 6 examples (whale, rainbow, cat, mountain and sun, heart stairs, shooting star), duplicate the ones you like, or change the mood to save a new version next to the original. Undo, redo and an eraser are always at hand.

FREE, WITHOUT AD SPAM
• No ads while you draw: no banners, no interstitials
• 4 instruments are free: Glass Keys, Kalimba, Soft Pad, Pluck Bass
• Music Box and Choir come with Tunebrush Plus, a one-time purchase. No subscription. Plus also adds three animated card styles (Star chart, Crayon and Record) and removes the small Tunebrush mark from your cards.
• Want to try first? Choose to watch a short ad and use a Plus instrument in that artwork. It is always optional.
• Sounds are generated inside the app, so drawing and playing work offline.

Available in English, 한국어, 日本語, 简体中文, 繁體中文, Español, Português (Brasil), Deutsch and Français.

The cat and the little bird templates are redrawn so they look like a cat and a bird. Template cards now always show the whole picture while the pen draws over it.
