In French, the word for piano is piano. It’s pronounced similarly to English, but with a slightly different accentuation.
When you say it in a French context, make sure to roll the ‘r’ slightly if it appears in a sentence. The pronunciation is typically smooth and fluid, reflecting the musicality of the word itself. For example, if you wanted to say ‘I play the piano’ in French, you would say Je joue du piano.
Overall, the word remains the same in both languages, which is a nice example of how some musical terms are universally understood, making it easier for communicative purposes.
