I preferred watching the live singers over experiencing harmonious in person at epcot. Watching the live stream made me realize what was missing in the park: it’s really hard to hear the music in the park and it is hard to appreciate the different languages.
When i saw harmonious in person, I didn’t realize they were presenting the songs in different languages until mid show when they hit a language I was more familiar with.
Generally, my brain simply maps English on top of a song I know well. The non English versions end up sounding muddled in the park, like I can’t quite hear what they are saying, but I already know the English lyrics so I follow along in my head… in English.
The Disney songs presented in English and the language of the story setting is a nice idea, but requires really good sound systems and subtlety. Fireworks are all about loud and spectacle which undermines that. They are inappropriately paired.
