I like to hear your singing
Hi, everyone!

I learned recently this way of saying things: "your/his/my..." + verb + ing. I would like to know if I understand it correctly and also if the other forms proposed by me are correct.
Is my following interpretation right?

I like to hear your singing = "singing" is here a noun, the act of singing.
So, it means that I like to hear when you sing.

Is "I like to hear your singing" different *in meaning* from the following sentences?
1) I like to hear you sing.
2) I like to hear you singing.
3) I like to hear when you sing.

Thanks!
Feel free to correct my English mistakes! :)

Answer

Yes, it is essentially the same. 1 and 2 can have some different contextual implications, but generally speaking they mean the same thing. 3 sounds a little awkward. More likely we would say, "I like to listen when you sing."

Answer

"I like to hear your singing"  > This sentence sounds odd to me , just like when I say " I like to hear your crying . It's better to say " I like to listen to your singing" or I like to hear you sing.
Your singing is so good . (noun)
" Singing" is a noun ( true) as well as to mean an action of the verb "sing" ( also true) , so how can you "hear" an act .

1) I like to hear you sing. > good
2) I like to hear you singing. > X > I like to listen to your singing
3) I like to hear when you sing. X > I like to listen to your voice when you sing ( likely example)
