I have been searching now already for quite a long time a website that does a similar job as the following websites:
Unfortunately, these websites are not what I am looking for. Basically on that website, the user could click into a prepared / empty common music notation template to enter a custom melody. Then after clicking on a Search Button, it would search for melody matches. The overall layout of that website had a brownish design and I think but I am very unsure that the underlying data was about chorales (but I may be easily mistaken about that).
A website which is very close to what I am looking for is Hymnary. The website that I am looking for presents at the beginning a single empty stave which allows the user to just click into the staff to enter notes one after the other.
During my search I found the following websites, but none of them is the tool that I am looking for:
Is there something I am overlooking here? I would be very grateful, if you may be able to discover the website that I am looking for. I think the website is already a bit older, since it did not have the newest design.
EDIT1: The website I am looking for looks almost exactly like CantusIndex
