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

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.
The present participle is formed by adding "-ing" to the base form of the verb, regardless of the tense. For example, "walk" becomes "walking" in the present participle form.
The perfect tenses are formed by using the auxiliary verb "have" followed by the past participle of the main verb. For example, in the present perfect tense, you use "have" or "has" followed by the past participle. In the past perfect tense, you use "had" followed by the past participle.

To form the present perfect tense, you typically use the auxiliary verb "have" or "has" followed by the past participle of the main verb. For example, in the sentence "I have eaten lunch," "have" is the auxiliary verb and "eaten" is the past participle of "eat."
use have and has subject + have/has + past participle + object. I have eaten the cake.
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.
