What is another word for bursts into song?
Pronunciation: [bˈɜːsts ˌɪntʊ sˈɒŋ] (IPA) 
When it comes to expressing a sudden desire to sing, there are plenty of phrases that could be used instead of "bursts into song." For instance, "breaks into song" and "starts to sing" can both convey the same idea while being slightly different. "Begins to croon" might also suggest a mellower take on the idea, while "joins in a chorus" or "warbles a tune" could indicate someone joining into an existing song. Alternatively, "carries on a melody" might cover an instance of someone singing a song already in their head, or "strikes up a tune" could be used for someone initiating a sing-along. Despite the variety of phrasing available, each one captures the joy and release of suddenly singing out one's feelings.
