Imperatives are addressed to you, but we don't say this pronoun, just using the verb (here sing). Example: you sing like an angel.

Please come to visit us, Mr. Blunderbuss is how we form the imperative here, using the infinitive to come without to. Example: now make yourself at home, Mr. Blunderbuss.

We do form the imperative here using the infinitive to come, but without to. We use the to infinitive in other structures. Examples: I want to come home; she likes to dance.

We could say Mr Blunderbuss comes to visit us, but it doesn't make sense to use that form of the verb when directly inviting him. Example: he thanks us for our invitation.

 Calm down, Timmy, don't cry is how we form a negative imperative, using don't + the infinitive without to. Examples: don't be late; don't dance like that.

We would say Timmy doesn't cry to talk about him to someone else, but not to tell him directly not to cry. Example: Timmy doesn't like you.

We could say Timmy, do not cry, but we can't form a negative imperative with not on its own. We use not to form the negative of to be and other verbs. Examples: that is not a good idea; I will not do that.

Buy one, get one free! is how we form this imperative, using the infinitive to get without to. Examples: Get up now! Go to work!

We could say he/she gets one free to describe what happens, but not to encourage someone to buy and get a free item. Example: she gets the shopping for her mother.

Got is the past, not the imperative, of to get. Example: we got free tickets for the movie.
