[Grammar] have your scales memorized

[nininaz]

Hello Teachers,
We use have something done to mean another person does a service for us.
So Why do we use ' have + something + done " in the following sentence?Because 'M' is going to do it by himself/herself and don't want to get somebody else to do something for her/him.

"M: Do you have any pointers for how to prepare for the audition?
W: Well, you will be tested on style, tempo, dynamics, scales, tone,
range, and sight-reading.
M: That’s a lot of stuff. What is the most important?
W: You’d better have your scales memorized and be ready for
sight-reading.
M: I know my scales. I’ve played the trumpet since middle school.
So, I’ll focus on my sight-reading."

No need for confusion. In your example, 'have' is a simple auxiliary. W could equally say ''You'd better have memorized...'. In the expression 'have something done', have isn't an auxiliary. It's a sort of 'pro-verb' (I made that up, on the analogy of pronoun) that stands for commission/arrange for/get... [although I suppose get is a bit of a 'pro-verb' too. ;-)])

Thanks for your help. I am not native speaker so understanding your explanation is so so hard to me .

We don't. It's not "having your scales memorized by someone else"

You had better have memorized them by the time you sit the audition. It's a strong recommendation to memorize them.

We use "have something done" to mean another person does a service for us.

We do, but we also use it when we tell someone else to do something (or, in the perfect tense, to have something done). In some cases, it doesn't matter who does it, but in your example, the context plainly indicates that it's you who needs to have it memorised.

I don't associate this use of "have something done" with the usage meaning "to arrange for something to be done". For me, it's simply an alternative word order.

You'd better have done your homework by the time I get back from work.
You'd better have your homework done by the time I get back from work.

"to have it done" simply means "make sure it's completed/finished".

"to have it done" simply means "make sure it's completed/finished".

Do you mean the following section is my answer?
4 have something ready/done/finished etc
to have made something ready to be used, or have finished doing something:

I should have the car ready by Monday

 

[BobK]

Yes :up: - although I don't think the example is very helpful, because it doesn't show the 'have + participle' construction - so you're forgiven for not getting the answer from a dictionary! 'I should have the job finished by Monday' would be clearer.
