Original Summary

Hi HN,<p>For a long time, I really wanted to develop my &quot;musical ear&quot;, but nothing seemed to be designed to teach me. That&#x27;s why I present &quot;Pitch Recognition&quot;, one of six free demos available without an account (more exercises after signing up, including relative ear training exercises).<p>For the musically inclined people, this exercise should guide you to connect each pitch with its name.<p>Please let me know what you think!
