Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele review for 2026

In our review of this course, we try to help you answer all of your most important questions about Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele as quickly and efficiently as possible, so that you can determine whether this online education training is worth your time and money.

Feel free to jump to whatever question you want answered the most.

Here’s what you’ll learn:

Why use MTIDCO5-PU as an abbreviation of the course name?

During our Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele course review, you might sometimes see us refer to it as MTIDCO5-PU for the following 2 reasons:

1. We created the acronym by taking the first letter of every word (which was very ingenious and innovative, we know)
2. We’re lazy and MTIDCO5-PU is simpler and easier for reviewing purposes

The full course name is 59 characters long, including blanks, while MTIDCO5-PU is 10 characters long.

You do the math.

Okay, we’ll do the math. We’re saving 49 characters every time we use MTIDCO5-PU.

So, just a heads up that we’ll be using this abbreviation sometimes, so you’re not left scratching your head and wondering what the heck we’re talking about whenever we refer to MTIDCO5-PU throughout the remainder of this review.

Is the Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele course for you?

To determine whether Rosa Suen’s Udemy course is a good fit for you or not, ask yourself the following questions down below.

The more you answer “yes” to each question, the more likely it is that you’ll like this course.

Can you understand what Rosa Suen’s course is about in 30 seconds or less?

Hopefully, you can easily grasp in 10 seconds or less what this online course is about simply by taking a look at the title that Rosa Suen chose for the course, “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele”, as well as its subtitle: “Create Your Own Circle & how to write 12 notes! Music Tool is Easy to Carry & Use – a MUST for piano, guitar, ukulele”.

This combo of title and subtitle should be enough to communicate the purpose of the training if Rosa Suen is a good, clear communicator (which, of course, you want in a teacher).

In our opinion, if you still don’t know what MTIDCO5-PU is about after looking at these two things, then this is a red flag, and you might be better off not taking this class.

Among other things, it means Rosa Suen hasn’t clearly and accurately conveyed what the course is about and might not be the best teacher for you.

For similar reasons, it’s important that you’re able to clearly understand what Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele is all about from the first few lines of the course description.

So take just a few seconds to read the opening lines down below and see what you think of them. 

Opening lines of Rosa Suen’s official description of MTIDCO5-PU

Rosa’s Online School:

OVER 25,000 Successful students have already taken my online courses since July 2014 with 877 – 5 Star Reviews

Course Updated: Nov 1, 2016

(Read more about this course on the official course page.)

Does MTIDCO5-PU pass the 30 Seconds Test?

You can read a lot more about Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele on the official course page on Udemy, but the point is this: are the title, subtitle, and just the first few lines of the description enough to help you understand what the course is about?

If so, Rosa Suen has done a good job and can be considered more trustworthy and a good communicator, which are important qualities for any teacher.

And, if not, maybe you’re better off looking at other Music classes that are more clearly defined and more tailored to your specific interests.

Did Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele appeal to you in 30 seconds or less?

Now that you’ve done the 30 Second Test with MTIDCO5-PU above, what is your gut reaction to this Music course with only the basic information of its title, subtitle, and the first few opening lines of its official course summary?

Did Rosa Suen do a good job conveying its subject matter, and did it immediately get your attention and appeal to you?

If so, Rosa Suen’s online course is certainly worth considering some more.

But if not, perhaps it’s in your best interest to consider some other Music courses instead, because clear communication and being able to hook and maintain your interest are two very important qualities for your online learning success.

Does Rosa Suen sound like a course instructor you’d like to learn from?

You’ve already learned how to use The 30 Second Test to make a quick evaluation of whether the MTIDCO5-PU course is worth taking.

We have a similar 15 Second Bio Test where you read only the first few lines of an instructor’s background — in this case, Rosa Suen’s background — and then you make a quick, snap judgment as to whether you think the instructor would be ideal for you.

There is no right or wrong answer. It’s just about going with your gut instinct. What might appeal to one potential student might alienate another, and vice versa.

(FYI, all Udemy instructors, including Rosa Suen, have a Udemy profile on their course page, so you can easily check for a bio and background on the Udemy website that way. We’re only including the first few lines of the bio down below for The 15 Second Bio Test).

Opening lines from Rosa Suen’s Udemy bio

Rosa is the Pastor and Church Pianist for a local community church in Hong Kong for over 30 years. She graduated from University of British Columbia and received her teaching certificate specializing in Chemistry and teaching English as a second language. She taught public schools in Canada for a couple of years and then went on to receive her Master’s degree in Christian Theological Ministry at Ontario Theological Seminary in Toronto. She started full time ministry with her husband in 1989 and received intensive Pastoral Counselling and Discipleship Training at Christian Disciples Church. They were ordained to become church ministers as Pastors in 1996 in a local church in Tsuen Wan and have been ministering to this same congregation for almost 20 years now.

(Learn more about this instructor on the official course page.)

What did you think about Rosa Suen after reading just the first few lines of the bio above?

After reading just the first few lines about Rosa Suen, did it make you more or less interested in taking the MTIDCO5-PU course?

And did it make you feel like Rosa Suen was more or less credible and qualified to teach Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele?

Finally, overall, did you feel like you’d receive the proper training from the instructor of this Music course?

As always, we encourage you to listen to your gut instinct, which is different for every student.

Are the MTIDCO5-PU lessons clear, specific, and organized well?

Part of the (good) problem with Udemy’s online courses, such as the Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele course, is that the instructors are constantly updating them, including adding and renaming lessons.

So it makes no sense whatsoever for us to list out all the modules and lessons in the MTIDCO5-PU course here, because you can just as easily go to the Udemy course page and get all the up to date course structure as of right now.

We do, however, have some tips about reviewing Rosa Suen’s course structure, so that you can get a better sense of whether this program is worth your time or not.

In a nutshell, you want to scan the the titles of the different sections and lessons of the course, and verify that they are clearly relevant to the course’s name, Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele, as well as the course’s subtitle, Create Your Own Circle & how to write 12 notes! Music Tool is Easy to Carry & Use – a MUST for piano, guitar, ukulele.

If the section names and lessons are clear, specific, and relevant, then it’s a good sign that MTIDCO5-PU is potentially a good, useful course for you, and you can have more confidence in Rosa Suen’s teaching abilities and lesson planning.

On the other hand, if the module names are confusing, vague, or irrelevant, then this is a red flag, which might indicate that the program is worth skipping.

Have you taken some free lessons from Rosa Suen that you enjoyed?

Have you already learned something from Rosa Suen that you valued or enjoyed?

For example, does the Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele training have some free lessons that you can try? (Almost all Udemy instructors will give you at least one or two lessons for free to help you make a better, more informed decision before enrolling in their course.)

But if you weren’t able to get any MTIDCO5-PU lessons for free, have you perhaps watched a YouTube video by Rosa Suen, or perhaps come across this instructor’s thoughts on Quora, Facebook, LinkedIn, Github, Reddit, or some other platform?

Or have you perhaps even taken one of Rosa Suen’s free courses or free webinars? (Many online teachers offer these freebies, which is a great way to get to know them and evaluate their teaching methods before buying one of their courses.)

In any case, the more familiar you are with Rosa Suen’s teaching methods, and the more you enjoy them, the more likely it is that Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele will be a good fit for you.

(P.S.: We strongly encourage you to seek out some free instruction from Rosa Suen before purchasing this course, since it’s one of the best ways to determine whether MTIDCO5-PU will be helpful for you.)

Are “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele” reviews generally positive?

On the bottom of the MTIDCO5-PU page, you can read student reviews of the class.

Prior to May 15, 2026, there were 100 students enrolled, 36 reviews / ratings, and it was overall rated 4.1 out of 5.

Obviously, the more highly other students rate MTIDCO5-PU the better, but no matter what, keep an open mind when reading the reviews, since you might still like a course a great deal that other students dislike.

After all, everyone’s got their own opinion.

We recommend that you spend only a couple minutes scanning the MTIDCO5-PU reviews to get an overall sense of them. You don’t have to read each one!

Is Rosa Suen responsive to student questions in the MTIDCO5-PU training?

You can see what other students have to say about this in their MTIDCO5-PU reviews.

But, our simple all time favorite way of gauging an instructor’s responsiveness is to simply email the instructor and see if or how they respond.

In this case, Udemy has a messaging system for students / anyone who has an account, and you can send Rosa Suen a message through this system quite easily, even if you haven’t bought MTIDCO5-PU yet.

For example, you could say, “Hi, and I came across MTIDCO5-PU while looking at Music courses on Udemy. If I enroll in your training, would you mind if I asked you any questions along the way?”

If you use this approach, the response (or lack of response) from the professor will tell you everything.

Obviously, the quicker the response the better!

Are you comfortable going through the lessons in Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele on your own, online?

This is a big one, because Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele is an online course as opposed to a course that you physically take in a classroom.

Of course, you will need a good internet connection to have access to the course material and lessons, but beyond that, you also have to be comfortable being self motivated to some degree, being on your own, and not having any physical interaction with any of the other students taking Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele.

Yes, you will be able to interact with the students and the teacher, Rosa Suen, online, but it’s a different kind of experience than what you’d get if you were interacting with them in person.

This is not a big deal to most people, but it might be something for you to consider if you feel like you do better taking classes in person rather than learning online.

Do the pros / benefits of MTIDCO5-PU make it worth your time?

Ideally, if you’ve gone through the evaluation steps above, you have a list of positive things about the Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele training that looks something like this:

• The purpose of MTIDCO5-PU can be clearly grasped and understood, and its lesson structure is clear, specific, and well organized
• Rosa Suen is well qualified to teach this subject matter, has good teaching abilities, and is responsive to student questions
• Other MTIDCO5-PU students have great things to say about the program

Other benefits include:

• You get to go through MTIDCO5-PU at your own pace
• You join a community of 100 other students taking the course
• You get lifetime access to the training
• All updates to the training are free
• You have a 30 day money back guarantee

Even if there are some things that you don’t like about the program, so what?

The question is simply this: do you think that MTIDCO5-PU would be worth your time, even if there are some things that could be better about it?

Can you comfortably afford MTIDCO5-PU?

Can you comfortably afford the cost of Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele?

This is an important question to answer, because even if you think MTIDCO5-PU sounds like the greatest online class in the world, it’s still not worth taking if you can’t comfortably afford it!

Before May 15, 2026, the price was $12.99 before any Udemy discount, and you were able to pay with a credit card.

Keep in mind that this is a Udemy online course, and there’s a great chance that you can get a solid discount on MTIDCO5-PU with Udemy coupons / promo codes, especially with the strategies we provide for helping you find the best, most popular coupons available.

We’ll cover that in greater detail in the next section, because at the end of the day, its important that you can learn whatever you want to learn without getting into a lot of credit card debt.

How can you maximize your discount on Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele?

By far, the easiest way to get the best and biggest discount on this course is to use the Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele discount code link at the top of this page.

It will instantly give you the best coupon code we could find for Rosa Suen’s online training.

We don’t believe there’s a bigger discount than the one we provided, but if for some reason you’d like to try find one, you can use the methods below to hunt for the best MTIDCO5-PU course coupons and promo codes you can find.

FYI, the methods below will help you not just with getting MTIDCO5-PU for a better price, but also with any other Rosa Suen Udemy course that you’d like to get for cheaper.

How can Google help you get a MTIDCO5-PU discount?

To use this method, do a Google search for the MTIDCO5-PU training, but in your search query, be sure to add words like coupon code, promo code, deal, sale, discount, and Udemy.

For example, you might do a search for “Udemy Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele promo code” or “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele udemy coupon codes” and see what turns up.

Similarly, you can use the same combination of search terms with Rosa Suen’s name and see what happens.

For example, you might do a Google search for “Rosa Suen Udemy coupons” or “Rosa Suen course coupon codes” and see if that helps you.

However, in general, it’s far more powerful to do a search for deals and coupon codes with the actual training’s name, than with the instructor’s name.

So in this case, for example, prioritize searches for “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele coupons” rather than “Rosa Suen coupons”.

How can a Udemy sale get you MTIDCO5-PU for cheaper?

Every once in while, Udemy will do a sitewide sale where they offer all (or almost all) their courses at a discounted price. For example, one of the best sales is where every course is only $10 or $9.99.

So, if you’re interested in saving as much money as possible, you could wait and see if you can get MTIDCO5-PU for this cheaper Udemy sale price one day.

The problem is that these sales only occur sporadically, so you might be waiting for a while. Also, if Rosa Suen decides not to participate in the site wide sale, then you won’t get a discount on MTIDCO5-PU, even though you could get a great discount on almost any other class at Udemy!

To understand this, think of there as being two different coupon categories for the MTIDCO5-PU course. Category one is an official Udemy coupon (which instructors can opt out of), while category two is a coupon offered directly by the instructor.

At the end of the day, it doesn’t matter what kind of a coupon tag you’re dealing with (for example, “officially from Udemy” or “officially from the instructor”), as long as long as as you’re dealing with active coupons that get you a better price.

How can you get a MTIDCO5-PU discount from Rosa Suen?

If you’re really serious about getting “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele” for the cheapest price possible, then perhaps one of the most powerful things you can do is get a coupon code straight from Rosa Suen, instead of waiting for a Udemy sale.

To do this, you can use either the direct approach or an indirect approach to try to get your discount.

With the direct approach, the big idea is to simply get Rosa Suen’s contact info in some way or another (whether it’s email, or Twitter, or whatever else).

Then you send a message saying something like “I’m interested in enrolling in Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele. Do you happen to currently have an active coupon code for it that I could use?” (And then, hopefully, you’ll get a reply with your discount code.)

On the other hand, with the indirect approach, you join Rosa Suen’s mailing list, if you can find it, and then you hope that at some time MTIDCO5-PU will be promoted to you at a discount.

By far, the more powerful approach is the direct approach, because it tends to get results faster. But you can experiment with the indirect approach and see if it works for you.

Can you get MTIDCO5-PU for free?

Of course, the best possible price for the MTIDCO5-PU training is free! As in, you pay no money whatsoever.

And guess what? Sometimes Udemy instructors provide coupon codes that enable students to take their courses for free. So, perhaps it’s possible that Rosa Suen has done this.

Basically, if you’re trying to get this program for free, you will want to search for the course’s name along with other words like free coupon, or 100 off coupon.

For example, you might do a google search for “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele free coupon” or “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele 100 off coupon” and see what happens.

But keep this in mind: often, Udemy teachers will offer a free coupon for their course when it first opens to get some publicity and reviews. And then, after a few days, they’ll make the coupon expired.

So even Rosa Suen has offered free coupons for MTIDCO5-PU in the past, the odds are likely they will all be currently expired. This is a common pattern that we have found.

What about a MTIDCO5-PU free download?

It’s important to understand that there’s a difference between getting full access to the MTIDCO5-PU training for free legally with a free coupon code vs. finding a way to download MTIDCO5-PU illegally.

If you really want to go the download route, you can do a google search for something like “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele download”.

And if that doesn’t get you the results you want, you can add the word “free” to your search.

For example, perhaps you could do a google search for “Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele free download”.

However, even if you get some results from these searches, we do not recommend that you take this course of action.

First of all, there are some shady sites out there that could be trying to infect your computer.

Second, Rosa Suen created this course and deserves monetary compensation for it.

And third, if you go the free download route, you’ll be missing out on a lot of value, because you won’t be able to ask the instructor questions or interact with the other 100 students enrolled in the program.

Can you get a refund on Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele if you don’t like it?

Let’s say that you used our tips above, and you were able to buy the MTIDCO5-PU training at a fantastic discounted price. So at this point, you’re super excited.

Then, you actually dive into Rosa Suen’s course, and you discover that it just isn’t for you for whatever reason.

And now you’re super bummed, because you feel like it wasn’t money well spent.

Well, guess what?

Udemy offers a rock solid 30 day money back guarantee on all their courses, so you can get a refund on MTIDCO5-PU no matter what. And this means there is absolutely no risk.

Indeed, even if you left a super negative, critical review on the MTIDCO5-PU training, and then asked for your money back, you’d get a refund. For better or worse, there’s nothing Rosa Suen could do about it, since it is simply Udemy policy.

To sum it up: yes, you can get a full refund, so at the end of the day, don’t worry about the possibility of purchasing MTIDCO5-PU and not liking it, since you can always get your money back.

What is OCP’s overall rating of Music Theory Intro: DIY Circle of 5th -Guitar Piano Ukulele?

During this MTIDCO5-PU review, you’ve learned about some of the unusual ways we like to evaluate courses, such as with The 30 Second Test and The 15 Second Bio Test.

So our overall review process is perhaps a little unusual and different from other reviews out there. Keep this in mind when you consider the overall rating / score that we have given this course.

Anyway, after taking a look at the MTIDCO5-PU training, the instructor, Rosa Suen, and reading what other students have said about this program, we give it an overall rating of 4.4 out of 5.

Ultimately, though, what matters most is what you would rate it based on the same criteria.
