How to Use the Apps
Find a QR code in your book.
Scan the code. Center the code in your view as if taking a picture.

The web applications are available for levels 5 through 12 and drill the student in the identification of intervals, triads, and major and minor scales. Also, there are apps designed to practice melodic and rhythmic dictation. All are customized to cover the same material and follow the same procedures as the TMTA state theory tests.

Keep in mind, these are web apps as opposed to native apps. Native apps are those that function on a particular operating system - an iPhone app downloaded from the App Store can only be used on an iPhone; an Android app downloaded from the Google Play Store will only work on an Android phone. Once downloaded, native apps do not require an internet connection to function.

A web app is different in that it works across a variety operating systems and devices - iphone, Android, Mac desktop, PC, and so on. A web app is housed in a web site, which means you must be connected to the internet to use it, and that the performance will vary depending on the strength of the internet connection.

How to Access the Apps

Use the web browser on your desktop, smart phone, or tablet. All these apps are housed at and are freely available.

To access the Intervals app for Level 8, for example, simply take the following route: --> Level 8 --> Intervals

The QR Reader

If you pefer, you can use a QR code reader for easier access to these apps. Throughout the Primo Theory series you will find QR codes which can be scanned with your smart phone or tablet if you have this reader installed.

It functions just like a URL, or link, which takes you to a webpage without the trouble of typing in the URL on your browser.

In order for your phone or pad to read the QR codes found in the printed text, you first need to install a QR code reader. Take the following steps:

  1. With your mobile device, open your App Store (iphone), or Market (Android), etc.
  2. Type "QR reader" into the search box to find the available apps - there are free or paid versions. Read the reviews and start ratings to decide which is best for you (a very quick and easy-to-use scanner is made by QR Code City, called "Scan: QR Code and Bar Code Reader" for iphone and ipad).
  3. Download and install the app. It is now ready to scan.

Follow the instructions given for each individual ear training app.

How to Use the Apps

Each type of app has a slightly different interface, but all are very similar in design and function. The main thing is to be aware that these apps act differently on a PC than they do on a mobile device.

On a desktop, the apps will stretch to fill the window size already in use.

This is what a QR code looks lilke:
You can alter the window size and the elements will adjust and stay in view (up to a certain point). For example, to make the window smaller, grab one end and compress the window.
On your desktop, if you cannot see all the buttons or elements, adjust the size.

Pull down until all elements are in view.

On your mobile phone or tablet, the apps will automatically fill the screen. However, depending on the angle you are holding your device or its size, some of the elements may be out of view.

Scroll up or down to bring the elements into view.

Scroll this area up or down
to pull elements into view.
