Where are custom exercise links?

In June 2013, we added in-exercise customization to all exercises. As a result, links to custom exercises are no longer shown on the exercises page.

If you are a teacher and wish to create links to custom exercises, please use the Exercise Customizer (listed under the “For Teachers” section on the exercises page).


Why can't I hear audio?

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

Alternatively, you can install Adobe Flash Player and disable any Flash-blocking extensions or browser plug-ins.

Which software instruments did you use?

For piano audio examples, we used samples from the following free instruments:

  • MDA Piano by Paul Kellett
  • Maestro Concert Grand by Mats Helgesson
  • Salamander Grand Piano by Alexander Holm

For woodwind and brass audio examples, we used products from Samplemodeling:

  • Double Reeds
  • Flutes
  • French Horn & Tuba
  • The Saxophones
  • The Soprano & Bass Clarinets
  • The Trombone
  • The Trumpet

For bowed strings, we used products from Embertone:

  • Fischer Viola
  • Friedlander Violin
  • Blakus Cello

While Samplemodeling and Embertone instruments cover the full range of musical expression, we opted to use a single dynamic along with a very gentle vibrato.

Proprietary samples were used for the remaining ear training instruments.

My teacher assigned a web exercise as homework. Can I complete it in Tenuto?

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

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

Tenuto will launch and ask if you wish to open the exercise. Select “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 info button and select “Show Progress Report” 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.


How can I assign exercises as homework?

On the Exercises page, click on the Exercise Customizer under the “For Teachers” section.

As you change various settings in the Exercise Customizer, 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.

How long do customized exercises remain available after creation?

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.

How do exercise verification codes work?

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.

Are keyboard shortcuts available in the exercises?

Yes, keyboard shortcuts are available on the web exercises when running on non-mobile devices. Common shortcuts include:

Shift + RReveal the answer.
Shift + NGenerate a new question
Shift + PDisplay the Progress Report.
SpaceReplay an ear training question.
EscapeDismiss Progress Report or dialog.

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