CelloDex

CelloDex helps cello players of all levels practice more effectively by scanning sheet music and displaying precise cello fingering information. Scan & Play Take a photo of any printed sheet music, and CelloDex instantly shows you which string to play on, which finger to use, and which position to be in. Smart Fingering Guide - Automatic string assignment (A, D, G, C strings) - Finger numbers (0-4) for every note - Position indicators (1st through 7th position) - Prefers lower positions for easier playing Built-in Practice Library - Open string exercises - Position reference charts for all 4 strings (1st-7th position) - Suzuki-level progressive exercises (Vol. 1-5) - Search, filter by string/category, and save favorites Sheet Music Display - Beautiful rendered notation powered by OpenSheetMusicDisplay - Position labels overlaid on the score - Detailed note list view with string, finger, and position info Recognition Engine CelloDex reads your score with KHEngine, our own optical music recognition server. It is selected by default and handles printed sheet music. A ChatGPT (OpenAI) engine is also available as a backup, and CelloDex switches to it automatically if the KHEngine server cannot be reached, so your scan still goes through. Results from the backup engine are less reliable — check them against your score. Recognition works best on clear photos of printed music, one page at a time. Handwritten scores are not reliably supported. Perfect for: - Beginner to intermediate cello students - Self-taught cello players - Cello teachers preparing lesson materials - Quick fingering reference during practice Start practicing smarter with CelloDex!
