As COVID-19 has changed the way people work, music teachers more than ever need to go online. Two tools are absolutely indispensable for every music school/teacher to embed on their website. A chromatic tuner, and a metronome. It should be customizable according to each‘s brand color, in different languages. For the metronome, the italian tempo should appear as well, and for the tuner, the hertz number should appear too. I think it’s a gold mine on music websites.
