Is the word musical the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical usage of "musical" are identical in both Brazilian and Continental Portuguese. The only difference is in pronunciation:

• Brazilian Portuguese: The "l" at the end of the word is vocalized, sounding like a "u" (e.g., mu-zi-cau).
• Continental Portuguese: The "l" is pronounced as a clear, alveolar "l" (e.g., mu-zi-kal).

Brazilian Portuguese Examples:

1. Ela tem um talento musical incrível. (She has incredible musical talent.)
2. Eu adoro assistir a musicais da Broadway. (I love watching Broadway musicals.)
3. O instrumento musical é muito antigo. (The musical instrument is very old.)

5. A trilha sonora do filme é musicalmente linda. (The film's soundtrack is musically beautiful.)
