Have you ever dreamed of having your very own CONCERT QUALITY MARIMBA, but you're unwilling or simply unable to pay the massive price tag?

...and imagine how much faster your skills will progress when you can practise at home and perform professional gigs on your very own instrument!

...and whats more, your personal satisfaction will be huge when you see the amazed reactions of your friends & peers upon seeing & hearing a completely professional marimba that you built yourself!

Have you ever looked at a Marimba in a catalogue or store and wondered…

"……Why on earth do these instruments cost QUITE so much?"

They figure if you want a professional instrument you just have no choice... right?

And boy oh boy... are these things expensive to buy! At the time of writing this, I could easily buy a brand new car with what it costs to buy a marimba comparible to the quality of this one.

And that's not even including the substantial delivery prices!


The P524 marimba is a completely professional quality instrument. After building the prototype, I am so pleased with th P524 that I am selling off the commercially produced instrument I have perfromed on for years, and I've decided to keep the P524 - it's that good. So now you can have a super budget price WITHOUT skimping on the quality!

So of course the EASIEST option if you want a concert marimba, is to spend between $10 & $20 THOUSAND - or even more for the best commercial instrument you can find.

but not all students, parents or schools have this kind of money...

even most professional marimbists would prefer to spend it elsewhere...

...and I bet YOU would prefer to have that money for other things as well!

That is why I’ve created this solution for You

You make it Yourself - and it's much easier than you might imagine!

Check Out my Video "Introducing the P524 Marimba"


You might think, this is too good to be true...

You might think, you really need special tools or materials...

You might think, it's only for people with good handyman skills...


DIY marimba with four or 5 octave range but this is a serious instrument, and the design is such that you can build it with just a few household tools, using only stuff from the hardware store... and even a complete novice in the workshop can build it!

You can make a Five Octave marimba - or a marimba of any range you like with this guide... and it will look fantastic & sound every bit as good as a commercial one.

If any of these apply to you, then read more.....

You are a percussion student or a parent of a percussion student, and you are looking for an inexpensive instrument for the home


You are looking for a proper professional instrument for performing solos or for a school music program.


You want a marimba that is really good for gigging on the road - easy to dismantle and transport - robust and designed to handle touring.


You are looking for a serious chromatic instrument – not a toy - but without the huge price tag of a commercial marimba.


Then I urge you to consider the plans available on this page and either making, or getting someone you know to make one of these instruments.

Firstly, let me introduce myself.

My name is Jim McCarthy, and I’ve been a percussionist for over 20 years.

I’ve always had a passion for building things, and over the years I've had a LOT to do with building and designing marimbas especially for other people to build. I’d never consider myself a professional at woodworking or trades though - I’ve always been a musician first.

and this means that if I can build this project... You can easily do it as well. You don't need to do any of the design, thinking, hard work and making mistakes - I've already done all that for you!

When I studied for my masters degree I got really into Acoustics and learned all about how Marimbas were built – I even made some massive, world record bass marimbas to indulge my hobby...

But recently my goals have been much more practical... I design instruments especially for people like you. It started years ago when I built a few simple instruments to assist my wife in her school music program. You may have seen the Project 1 Box resonated Xylophone, or the Project 3 mini-marimba which people all around the world are already building to save money for their schools, as well as being interesting to play and enjoy for children.

Introducing the Project 524 Professional Concert Marimba Plans

In “Project 524” you have everything you need to build marimbas yourself, including:

Part 1 - Step by Step Instructions in an incredibly detailed and massive 170 full size page E-book - packed with all the info you could ever need to build marimbas in the four to five ocatve range - or even custom design your own.

build a marimba DIY ebook

Your e-book features over 800 Photos and diagrams showing every step of the process in meticulous detail - nothing is left for you to "guess" and there is every piece of information you need.

Part 2 - 5 instructional videos for tuning bars - almost 2 hours worth! Includes fine tuning of the overtones, wedging for the cross tones, finding and using nodes and more!
How to tune a marimba bar video

So all the hard work is done for you, and you’ll even have included:

  • The exact measurements of the bars that work every time - including the new enhanced bass bar design.
  • How to drill and mount the bars in the correct way to ensure that every note sings clearly
  • How to build the resonating tubes out of easily and readily available materials
  • How to raise or lower the pitch of the bars by working in the correct places
  • Alternative tuning placements for harmonics that work even for those problem bars.
  • How to avoid problems with "cross modes" by wedging the bars.
  • How to tune all the important harmonics (overtones) on the bars to make them sound pure, tuneful & resonant.
Plus you get these cool FREE Bonuses!

Plus Cool BONUS #1!

There's no doubt you'll prefer playing on your concert marimba, but nothing beats this simple glockenspiel for portability, ease of build and small cost of build. This building guide is not a soft bonus either - it's 23 pages tightly packed with loads of photos and all the details you need for a fantastic result with zero thinking!

Considering you get to build two instruments for the price of one, this bonus makes the whole deal a real no-brainer!

Plus Cool BONUS #2!

free sheet music for your home built DIY marimbaOnce you have your instrument finished you will want to play something on it.

Frequently Asked Questions about Making Marimbas...

Do I need special wood for the bars?

Generic hardwood can be used to build a basic set of marimba bars

The great thing about this project is that it will work for you, no matter what wood you have available. This project is aimed at those who want a concert quality instrument so the wood you use for the bars IS important. It is discussed in great depth in the guide. Commercial marimbas are usually made from Honduras Rosewood or African paduk, and obviously the better wood you have access to the better instrument you’ll be able to make. However you can make this instrument from just about any hardwood (eg, Durian or Meranti) if you want to save money - and it will still work. And there's nothing to stop you making cheaper bars to start with then better ones from more expensive timber later on! The bars in the prototype are made from African Paduk - and you can hear how good they sound in the video higher on this page.

How much will the materials Cost?

Depending on where you live you should be able to get all the materials you need for way less than $2K - and that includes using more expensive timber for professional level bars. Of course this will be way less if you use cheaper timber or if you build an instrument with a lesser range than the full five octaves. Other than bar timber - all the materials can be purchased from the local hardware store.

Does the plans include both Metric and Imperial Measurements?

YES! The plans include both imperial (feet and inches) and metric (millimetres) measurements.

Do I need to be good at woodworking to achieve this?

building a DIY marimba at home with the making marimba plans

Absolutely not! I’m not a carpenter - I’m a musician. Most of the skills required are fairly basic woodwork – measuring, cutting and sanding.

Even if you’ve hardly ever picked up a hammer or a saw in your life I’m confident that you’ll be able to achieve a great instrument using these plans. Of course even though I'm not a carpenter, I've picked up a few clues over my time designing and building instruments - but I've put all the important construction tips in the package for you.

Do I need lots of expensive tools?

Absolutely not! All of the tools you will need are common houshold tools.

Things like:

  • An electric drill with a sanding attachment
  • A screwdriver
  • A wood saw
  • A small hammer
  • Sandpaper and sanding discs
  • Hacksaw
  • Rivet Gun

Plus a few other bits and pieces commonly found around the garage!

Do I need any special tuning equipment?

tuning a marimba bar

Obviously the better your tuning, the better yoiur instrument will sound. It IS possible to tune a marimba purely by ear, but at least a basic electronic tuner is highly recommended. Any chromatic tuner will do the job, and you can get a really basic electronic tuner from any music store for around $50, or simply borrow one from a friend to get the job done! These tuners are incredibly common – nearly all professional musicians or music teachers either own one or have a friend who owns one.

BUT... if you don’t have access to one, don’t worry – as I’ve included a full set of sine waves (clear and clean tones) that you can use to tune the notes by ear. If you have a musical ear it is really easy to do it this way.

If you want to make life even easier, and get a fully professional tuning result, Peterson make tuning software you can buy online for less than $100 USD - which is PERFECT. All these various options are thoroughly discussd in the building guide.

Is my homemade instrument going to sound as good as commercially available instruments?

With THIS building guide - that is certainly possible!

If you use the same timbers as commercial manufacturers do and tune your bars as reccomended in this guide - then there's no reason why your marimba can't sound JUST as good!

Does it matter what the resonators are made out of?

This is definitely one of the biggest areas of misunderstanding for most people.

making the marimba resonators and tuning the resonators

The fact is that it makes very little difference!

Comercial instrument manufacturers will often TALK about the sounds of different resonator materials - they want to make their instruments seem more special - BUT have you EVER seen anybody publish an actual audio comparison?

and think about it......The resonator's job is to amplify the sound – and it does this by containing a column of air which is the correct size to resonate when sound waves from the bar enter it.

So... does the column of air really care what is containing it? or does it even know? Remember it’s the column of air that is vibrating.. not the container, so what it's made from really makes very little difference!

and I've heard people argue that certain materials are a little harder and reflect sound better than others - well this is true... but here's the thing...

Extra hard metals etc only make a difference at quite high frequencies - the frequencies way above the range of marimbas. Only the upper harmonics of marimbas are in this frequency range - and guess what... these upper harmonics are actually tuned to NOT resonate in the tubes!!!

The plans included for this instrument use PVC pipe for the resonators because:

  • They are lightweight
  • They are inexpensive
  • They are easy to work with
  • They don’t require heavy duty hardware to hold them in place

And you can get PVC pipe at just about any hardware store, as it is usually used for drainpipes around just about any home! Of course - if you really want to use different materials for your resonators, there's absolutely nothing stopping you. The building guide still tells you how to get the result you are after.

Do I have to wait for anything to be shipped to me?

Absolutely not! You have instant access to the e-book and videos via download, so you can get started immediately. The plans print out in Adobe Acrobat Reader (which is a free download, and nearly every computer already has it installed anyway).

Can I adapt these plans to build a different range instrument (not 5 Octave)?

Yes Absolutely! In fact this design is called the P524 because it was created with all the possible ranges from five octaves to four octaves specifically in mind. And because the guide takes the approach of actually showing you how to find the critical measurements you need, they are all just as easy - and you could even make a bigger or smaller instrument just as easily!

How Much do these plans Cost?

Your P524 Marimba building guide is just $73 USD If you are not in the USA - You can just go to and check it out in your currency.

and this is actually a tiny price for the plans when you consider:

  • The length of time that I had to study acoustics, as well as research and develop building techniques in order to bring these plans to you
  • The massive content - 170 A4 sized pages packed with detail including over 800 photos and diagrams AND the almost 2 hours of video going through all the bar tuning processes step by carefull step.
  • The trial and error that I went through in designing frames, tuning bars and resonators and selecting materials, that you don’t have to!
  • The money you will save on your instrument - even just the money you will save on wasted materials by NOT making the mistakes that I've already made FOR you!
  • The absolute impossibility of finding this information out through other sources – I scoured books and the internet for AGES – and the information you need to build a fully professional concert marimba yourself is simply not available anywhere but here.

The informational products available at and are designed to give the user all the information required to build the corresponding instruments to the same level and finish as the original prototypes pictured on the websites. The final results produced by the end user are naturally dependent partially on their own abilities and efforts. Some of the skills and techniques described in the building guides may require the end user to practise a little before a high proficiency is achieved. This is an expected part of the building process. Once these skills are sufficiently achieved however, the end user if using due care, should be able to build an instrument for a significantly lower cost than that of any commercially equivalent model.
