Musictheory.education is finished and online, after 10 month of translating, building and testing.
For the translation I had the fantastic help of Christina Viola Oorebeek, an American-Dutch composer.
Making Musictheory.education was only possible because of her help, so I would thank Christina for doing this huge amount of work.
A short overview of what has been done: the translation of 289 chapters, 123 videos, 261 exercises and many images.
