I do not see the option to upgrade to Mapping Tonal Harmony Pro 8 on my iOS App Store. Why?


The App Store automatically recognizes your device and offers the latest version of the app that’s supported by your iOS. If the app store does not offer version 8 it probably means Mapping Tonal Harmony Pro 8 is not supported on your iPhone or Ipad.

I bought Mapping Tonal Harmony Pro on my iPhone/iPad and I would like to have it on my computer as well. Do I have to pay again? How about Add Ons?

(macOS) (iOS) (The Jazz Standards Progressions Book)

All apps and Add Ons are sold separately for macOS and iOS. This is as per Apple’s App Stores. We tried to make add ons available across platforms but Apple did not allow it. So we lowered the prices to make them more accesible, taking into account that most of our clients will want to have these features on both iOS and macOS.

The best option we found to make this materials more accesible for everyone is to offer the xml file with 1300+ Jazz Standards and the Bird BeBop progressions available on our website. This xml file is included for free in the PDF book packages we offer. When the xml file is purchased from our website, it can then be imported into macOS and iOS and the customer has to pay only once.

The individual xml files for The Jazz Standards Progressions Book and The Bird BeBop Progressions Book can be found here:


The Jazz Standards Progressions PDF Book bundles with free xml files are located here:


The Bird BeBop Progressions PDF Book bundle with free xml file can be found here:


All other apps and add ons are sold separately for macOS and iOS.

Why is Mapping Tonal Harmony Pro macOS at version 7 while the iOS version is 8?

(macOS) (iOS)

We are developing Mapping Tonal Harmony Pro 8 for macOS. We will upload it to the App Store as soon as it’s ready for prime time. Customers currently using Mapping Tonal Harmony Pro macOS 7 will get this update for free. We do not have a release date for it yet but as of February 2021 it is our top priority.

Can I import/export music xml files into Mapping Tonal Harmony Pro?

(macOS) (iOS)

Yes. It can import xml files from iReal Pro

Can I export Mapping Tonal Harmony Pro xml files into other apps such as Logic Pro or Sibelius?

(macOS) (iOS)

No. Mapping Tonal Harmony Pro uses non-standards xml files, not music xml files.

We had to develop our own xml technology so the app can relate harmonic functions, chord and chord-scales and place them in the visual map. Music xml files do not have that information.

Can I import audio into Mapping Tonal Harmony Pro and have the app do the harmonic analysis?

(macOS) (iOS)

No. That is not the way Mapping Tonal Harmony Pro is intended to be used. Mapping Tonal Harmony Pro was envisioned as an audio visual tool to help with the study or Tonal Harmony. The idea is to learn about tonal harmony and be able to make our own analyzes. By placing harmonic functions in an specific spot in a visual landscape we relate harmonic functions with one another. We made the Mapping Tonal Harmony Pro Workbooks. These are 7 volumes that correspond with the seven levels of the map so musicians can learn all about each harmonic function and use the exercises in the Workbook to practice. The workbooks can be found here:


(Please scroll dow all the way to the bottom of the page to find these Workbooks)

Does Mapping Tonal Harmony Pro work on a MAC simulator running on a Windows computer?

No it does not.

What are the pros and cons of Mapping Tonal Harmony Pro macOS versus iOS?

Mapping Tonal Harmony Pro macOS and iOS versions are kept pretty much the same. There are no differences in functionality or features.

The obvious pro for the iOS version is its portability. The capacity to carry the map with all the harmonic functions, and the entire repertoire in your catalog with full harmonic analysis, etc.

Having this in you pocket or on a iPad at gigs, lessons, rehearsals, etc is a great help.

Personally I enjoy the macOS version better because Mapping Tonal Harmony Pro is a pretty involved app. I like a having a large screen and to be able to arrange my workspace as I need it. Of course this is just my personal preference.

Ideally I think it’s best to have both versions and enjoy what each of them has to offer.

How is Mapping Tonal Harmony authorized if i buy it from your website via PayPal? Do i get a license file?   Does it work online or offline? And on how many of my computers (desktop and laptop) can be used?

Once you purchase the app via Paypal the website will offer you a download button. The app is then downloaded on you Downloads Folder. All you need to do is move the app inside the Applications Folder on your computer.

The first time you run it, it will ask to activate using your email address.

Mapping Tonal Harmony Pro works offline.It can be used on up to three computers, desktop or laptops.

Is Mapping Tonal Harmony 5.0 for Windows still available?

The Windows version Of Mapping Tonal Harmony Pro (5.0) became obsolete and is no longer available. We plan to migrate our products to Windows and Android at some point but it will take a long time.

While we prepare these projects, we made several PDF products to deliver our concepts and teaching philosophy to Windows/Android users. These products do not offer the fancy features of our apps, but all the concepts are in there for those who wish to study them.

The equivalent to Mapping Tonal Harmony Pro is The Composer’s Guide to Tonality (Mapping Tonal Harmony Pro PDF app) and it’s available here:

2- Click on the top-right corner of the bottom split to open that menu

Can I enter chords manually instead of choosing them from the map?

(macOS and iOS)

No. The reason you can’t type a chord is that you aren’t only selecting a chord. You are selecting a harmonic function and a chord scale associated with it. It happens to be a certain chord in the key of the moment but it will change accordingly if you decide to transpose the whole song to any other key. Mapping Tonal Harmony Pro relates the coordinates in the map with it’s harmonic function and attaches a chord scale that goes with it. This is a much deeper and more intelligent process than entering a chord manually. The point is to learn about harmonic functions and the way they work in tonal harmony.
