Musical scale question type

From MoodleDocs


The music scale question type deals with musical scales and may be useful for music theory instruction at the high school or college level. Answers are entered in a graphical user interface.

Current Features

  • A question bank in Moodle XML format is provided, including all major and minor scales, with and without a key signature.
  • Mutiple answers may be configured for specific feedback or partial grade
  • A graphical user interface is used to enter answers

Some Ideas for Future Development

  • Use the Flash interface to enter question options when creating or editing a question
  • Add optional, built-in automated feedback on various wrong answers


  • Moodle 2.3 or 2.4 (as of july 17th 2013)

Note: An older version of this plugin worked with Moodle 1.9.4, 1.9.5, 1.9.7 or 1.9.8 (it may work with other versions within 1.9, but has only been tested with these four versions)

  • Javascript must be enabled to allow for communication between PHP and the Flash interface


  • Download the Zip file from the Moodle Plugins database.
  • Copy the "scale" folder into the following folder: {moodle root}/question/type
  • Log in as administrator and load the "Notifications" page on the Moodle home page - this will create database tables used by the question type
  • Within a quiz, select "Scale" in the "Create new question" dropdown menu


  • Failed to load question options from the table question_scale for questionid xxx: The likely cause for this error is that a required database table is missing. To correct the issue, load the "Notifications" page on the Moodle home page (located just under "Site Administration", while logged in as administrator). Please note that any question created before fixing this issue will have to be discarded.
