Photograph the music, then choose a fingering
The page is recognized locally. The violin or viola planner weighs shifts, string crossings, hand position, stretches, open strings and tone color across the whole passage. It draws finger numbers back onto the photographed page.
For the best reading: printed music, a flat page, the whole staff width in frame, and even light. Open a multi-page PDF to navigate thumbnails and export one annotated PDF. Tap any wrong pitch to correct or remove it.
