How does it sound? Listen and watch.

Listen again to the sentence you have just heard. Listen to the melody of the sentence: the voice tone raises in the last stressed syllable (bo-) and falls in the ending syllable (-na).

Now listen to the sentence as many times as you want and pay attention to the graphic. Watch (and listen) how the voice rises in the last stressed syllable of the sequence (bo-) and, next, falls until the end of the sequence.
