What's the difference between "sang" and "sung" ?

Are the both past tense of to sing?

"I sang karaoke last night" and "I sung karaoke last night"

I'm a native English speaker. Both of these example sound correct to me, but I'd never say the second one.

It's good that you would never use the second one because it is wrong. The conjugation of the verb sing is "sing, sang, sung."

Now I sing a song.

Yesterday I sang the same song.

Actually, I have sung the song many times.


Sang is the past tense form of the word sing. Sung is the past participle of the word sing.


Your instincts are right. "Sang" is the simple past tense; "sung" is the past participle. "I sang karaoke last night." "I had never sung karaoke before."

Actually, the American Heritage Dictionary gives "sung" as an alternate past tense form, but I still wouldn't use it that way. People probably won't correct you (so you won't have a chance to defend your usage by citing an authority), but they're likely to think you're not very well educated.


'Sang' is the past tense of sing, so it's correct in your example. 'Sung' you would use for example in 'the song was sung loudly'. I could be wrong - I'm sure someone will correct me if I am - but I think that's the subjunctive tense.


When using simple past tense statements, use sang. In more complex statements, use sung.

Example: The anthem was sung with strength and grace. He sang it as if the notes were springing from him as a new song.


One is simple past and one is past perfect.

I sang karaoke last night.

I have sung karaoke at that bar many times before.


Actually, Rhea, there is no difference.

(Well... only as much difference as...

for example: "right" & "correct")

You can trust me on that, because I

know about this.


Both are acceptable, it's the english language for you....chock full of slang words made into real words.

Did you know "ain't" is a real word...when it was previously not?
