"What music do you have?"
Translation:Какая музыка у вас есть?
When the question is "What music do you have", I suppose the inquirer knows the person has a music, but doesn't know what music it is. So, as long as I guess the existence of the music is not on debate, but just what music (or what kind), so I wrote: Какая музыка у тебя", omitting the "есть", but I got it wrong.
Non native, but I've spent a lot of time with teachers/tutors/friends on this question. The emphasis here is on the person HAVING music. When the emphasis is on having something vs the quality of something, you tend to use есть. For example:
Does he have eyes? (weird, but bare with me) У него есть глаза?
Есть is used here because the paid is on having eyes versus...
Does he have blue eyes? У него ГОЛУБЫЕ глаза?
The emphasis here is on the quality (blue) of the eyes with the underlying assumption he already has eyes, but we want to know if they are blue.
So I guess this sentence would sort of be like, "What kind of music, if any, do you have?" Question about the direct quality of music would be more like "do you have rock music?
Of course this is still general and it is possible to still use есть in this case if emphasizing that you have a quality that was asked about.
Who here has blue eyes? (in general) У кого-нибудь здесь голубые глаза?
Who here has blue eyes? (as in the ones ive been asking about, I'm searching for, or that we just talked about, etc) У кого-нибудь ЕСТЬ здесь голубые глаза?
of course, an excited person who puts up and says...
I HAVE blue eyes. У меня есть голубые глаза.
As for my understanding, it would be even wrong to put a ест in that example phrase. I see it as "How are things with you?" "Fine . And with you?" У taking the place of "with". No verb involved. I think "А у вас ест?" would rather be a more appropriate question to a situation like "I have a four of aces. And [what do] you have..?" A question emphasizing what the inquired has as opposed to somebody else.
We almost always put the question word in the beginning, so this sentence sounds unnatural.
