오늘은 춤추고 노래해

The line, explained

Some songs are just permission to have fun. 오늘은 춤추고 노래해, today we dance and we sing, is the kind of line a whole stadium shouts back, hands in the air. It is simple, joyful, and a great way to learn -고, the ending that links two actions together the way 'and' does in English. Once you have it, you can make your Korean sentences twice as long.

오늘 means today, and the 은 attached to it is the topic marker. It gently highlights today as what we are talking about, with a hint of contrast: whatever happened yesterday, whatever tomorrow brings, today is for this. The final ㄹ of 오늘 slides into 은, so you hear o-neu-reun. Time words like this usually come first in a Korean sentence.

춤추고 is 춤추다, to dance, plus 고. 춤 means a dance and 추다 means to perform a dance, and together they are one verb. The 고 attaches straight to the stem, never changing shape, and means and. Think of it as a hook that grabs the next verb. You can chain several: 춤추고 노래하고 놀아 means dance and sing and play.

노래해 is 노래하다, to sing, in casual form. 노래 means song, and 하다 means to do, so singing is literally doing song. Many Korean verbs work like this, which is great news for learners: 공부하다 (to study), 운동하다 (to exercise), 사랑하다 (to love). In casual speech, every 하다 becomes 해. Only this last verb shows the tense, so the 고 verb borrows it.

That borrowing is the key trick. 춤추고 노래했어 means danced and sang, because the past tense on 노래했어 covers both. You never need to mark the tense twice. -고 can also mean and then, showing order: 먹고 자 means eat and then sleep. Try swapping the first verb: 오늘은 웃고 노래해 means today we laugh and sing, and 오늘은 놀고 노래해 means today we play and sing.
