YouTube may soon let users find a song by humming its tune

YouTube testing feature that will allow users to search for a song by humming it. This feature, which is not new in the smartphone space, is a handy way to find a song on a phone when all you know about it is its tune.

According to a support page, Google announced that testing this functionality on YouTube as part of an experiment — new tools and features (sometimes also called “betas” or “experiments”) are usually available for a short period of time and only for a small group of people.
