No, most of the site is accessible without Adobe Flash Player installed. That said, some features still require Flash:

• Lessons use Flash for animations and audio examples. If Flash is not installed, you can still view the lesson text and still images.
• If your web browser lacks Web Audio API support, Flash will be used to play exercise audio.
• If your web browser lacks HTML5 Canvas support, Flash will be used to draw certain exercise graphics.

Yes, you can find all of these on the Classic Edition at classic.musictheory.net.

Absolutely! We appreciate all links to the site! In addition, you may embed any lesson, exercise, or tool using HTML frames. For example, to embed Note Identification in your site, use the following markup:

Tenuto and Theory Lessons are compatible with all devices running iOS 5.0 or later. This includes all models of iPhone, iPod touch, and iPads except for:

• iPhone (original)
• iPhone 3G
• iPod touch (1st generation)
• iPod touch (2nd generation)

For more information about device models, see Identifying iPhone models or Identifying iPod models.

No Android version is currently planned. Much of the site works in the Android web browser, however.

Yes, with the latest version of Tenuto, you can create official Progress Reports.

First, open the exercise in Safari on your iPhone, iPod touch, or iPad and select “Open Exercise in Tenuto”:

Tenuto will launch and ask if you wish to open the exercise. Upon selecting “Open”, your existing customizations will be overwritten with those from your teacher, and your score will be reset.

Once you complete the exercise, tap the sticky note to display the Progress Report:

Next, tap the Share button at the bottom of the report:

Select Mail to send the report via e-mail or Print to print it out. You can also share your progress via Twitter or Facebook.

First, use the Exercise Customizer to create a customized exercise. As you customize the various settings, the web address at the bottom of the page will update.

This address is permanent and will always point to the customized exercise. You can link to it from your Course Management System, write it down on your whiteboard, or e-mail it directly to your students.

Exercises are designed to be never-ending and present questions to your students indefinitely. Hence, you will want to assign a completion criteria along with the exercise. Some teachers simply tell students to “Answer 100 questions correctly”, others prefer a time based approach: “Practice this exercise for at least 15 minutes with at least 30 correct answers”.

A student should hand in a signed Progress Report to prove that he or she completed the exercise. To create a report, a student first clicks on the Gear icon in the top right corner of the exercise and selects “Show Progress Report”:

Next, the student signs the report by entering his or her name into the “Student Name” box and clicking “Sign Report”:

Finally, the student can print the report with the “Print Report” button at the bottom of the page:

Each Progress Report has an associated Verification Code. In addition to preventing common occurrences of cheating, these codes allow you to access the original report. Hence, you can allow students to electronically send you the verification code rather than physically printing each report.

To verify a code, use the Code Checker tool.

Customized exercises are permanent and do not expire. If you previously created a customized exercise and the URL no longer works, or experience other issues, please contact us.

Verification codes require a student to enter his or her name into the exercise's Progress Report. Once entered, the name cannot be changed until the score is reset. This prevents a common occurance of cheating: a student printing off multiple copies of a report for friends.

Other cheating strategies involve altering the report's score or forging it completely. Verification codes are uniquely generated based on the student's name, exercise settings, and score. While a student could reverse-engineer the cryptographic algorithms used to create the code, doing so involves more effort than completing the assignment.

The codes also allow results to be transmitted electronically. In the Progress Report, right-click on the verification code and select “Copy Link”, “Copy Link Location”, or “Copy Shortcut” (depending on your web browser). This will copy the permanent URL of the report to pasteboard. A student can then paste the code into an e-mail message or course management system. Since the URL contains everything needed to reconstruct the progress report, no additional information is required.

Yes, common shortcuts include:

In addition, some exercises have shortcuts for the answer buttons. Hover over a button to reveal shortcut information.

In order to hear audio in the exercises, you need to use one of the following:

• Google Chrome 14
• iOS Mobile Safari 6 (or higher)
