Hello, I'm Volteer1. I noticed that you added or changed content in an article, Absolute pitch, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. &#8209;&#8209;Volteer1 (talk) 14:14, 17 May 2021 (UTC)
