Have you ever sung your sweet soul out in the shower? Do you like to sing? If you’d like—sing a song about the proper tenses of the verb sing—now would be a good time do so. Let’s answer some common questions on the verb and topic of today’s post: what’s the past tense of sing?

“Sang” or “sung”: which is correct?

When to use sang or sung

simple pastShe sang the national anthem.
present perfectShe had sung onstage before, but stopped because of her stage fright.
sang vs. sung

Both forms of the past tense depict events which started and ended in the past, but the present perfect carries a different relation to the present than the simple past. Remember that simple tense constructions are complete tenses that don’t use auxiliaries. Perfect and continuous tenses are easy to identify because they use auxiliaries; namely, forms of “to be” and have/has/had.

We use the past perfect to stress the order in which past events unfolded. For example, “she’d sung onstage but fallen off within minutes while the crowd applauded“.

This sentence is in the past perfect tense, and it helps make it clear that the singing took place before the falling off of the stage. To write in the simple past tense, we do not require a helping/auxiliary verb, such as has, had or have. If this is all confusing,  we recommend Grammarflex’s article on participles and verb tenses (which are a real linguistic crackerjack, to be sure).

Sang vs sung: what’s the difference?

Is sing a regular or irregular verb? The difference between regular and irregular verbs is regular verbs end in –ed in their past tense forms. Irregular verbs end in something other than –ed. This makes the action and verb sing quite irregular, since its past tense forms end in something other than –ed in both the simple past tense and past participle: sang and sung). See other verbs in the same class of irregularity:
