A woman with dementia might still recognise the tune her father…
A woman with dementia might still recognise the tune her father wrote. Her great-grandchild has photos of the handwritten score, cannot read music, and reports the scanning apps simply fail on it — 936 points and 108 comments later, the thing that worked was a stranger spending two hours by hand.
What is the idea?
Photograph the pages of an old, creased, handwritten or badly printed score; get back the piece as something you can press play on — plus a clean readable copy if you want one.
Why would anyone bother?
The people holding these pages are not musicians. They are descendants with a folder of paper and no way to hear what is on it, usually while someone who would recognise it is still alive. The window closes.
What is missing today?
Every existing tool ends at a PDF or a MusicXML file — an artifact only a musician can use. A pro in the thread had to spell out to the OP that what he actually needed was an audio export, not the PDF he asked for. Nobody has built the version that skips straight to sound for someone who cannot read music.
What makes this one different?
Sell the playback, not the transcription, and scope to one folder of family paper rather than a general OMR engine. Ship the uncertain bars visibly marked so a musician friend can fix twelve of them in five minutes instead of transcribing from scratch for two hours. Cold start CN = 小红书/豆瓣 搜「老乐谱」「爷爷的谱子」与家族记忆整理类笔记，以及简谱吧; EN = r/piano and r/musictheory, where a transcribe-this-for-my-family request surfaces every few weeks and reliably draws volunteers.
What is the sharpest thing about it?
Optical music recognition has existed for twenty years and works on clean printed scores. Reading a wrinkled, smudged, hand-engraved page — which is what every score inherited from a family actually looks like — is the part that only became plausible with multimodal models, and the OP hit exactly that wall.
What could kill it?
OMR on degraded handwriting will get notes wrong, and a wrong note in a piece someone's grandmother might recognise is worse than no note. The thread shows the correction cost is real: two expert readers argued over a dozen specific bars in the human transcription. Any honest version has to show its uncertainty and make correction easy, which is a harder product than the demo.
Who pays, and for what?
One-time payment per folder, in the same bracket people already pay to digitise family photos and cine film; the printed clean score is a natural physical keepsake upsell.
What is the main risk?
Published music is under copyright — the product must be scoped to paper the user owns and to private playback, and must not become a route to free sheet music for current repertoire.
What did real people actually say?
Verbatim from the public sources linked above, not paraphrased: “I have pictures of the music but the scan apps just don't work.” — reddit-post “Yeah that's what I tried but it simply didn't work, I think it's cause the paper is so wrinkled and smudged” — reddit-comment “If you don't have someone who can play, what you actually need is someone to input it into notation software (creating an XML file) and then export it as an audio file, not a PDF.” — reddit-comment “In reality the whole thing took me a total of about 2 hours” — reddit-comment
How much work is it?
about two months of work
