Other forms: musicals
Anything musical has to do with music. Tra la la! If you’re really musical, try out for a musical so you can sing on the big stage. And, if you’re playing musical chairs, better find a seat before the music stops!
Musical things have a tune or rhythm, like a robin’s song or "La Cucaracha." Musical instruments, like clarinets and guitars, make music. Or hope to. The bands you’re into reflect your musical tastes. If your parents are musicians, you come from a musical family. When musical is a noun, it's short for "musical drama." The Sound of Music is a musical (film) about the musical (talented singing) Von Trapp family. Guess what they’re into.
