You use the past participle (e.g. have/has sung) when the subject is being talked about in the present (the present perfect tense).

There are two forms of the present perfect tense: simple present perfect (I have eaten) and progressive present perfect (I have been eating). Both forms use "have" or "has" with the past participle of the main verb to indicate an action that started in the past and has relevance to the present.
When using "have" or "has" in combination with the past participle, you are creating present perfect tense. "Have" is used with plural pronouns (I, you, we, they), and "has" with singular pronouns (he, she, it). This construction indicates actions that started in the past and continue into the present or are relevant to the present.
Using "have" with the past participle of a verb forms the present perfect tense. This tense is used to indicate an action that was completed at some point in the past and has a connection to the present.
