Music Critic

Music Critic
MusicCritic is a set of technologies with which to facilitate the assessment of musical exercises in the music education context.

Background

MusicCritic is designed to transform online music teaching/learning towards a much richer experience for both teachers and students. It provides support technologies for online music education, facilitating the assessment of student performances and the two-way communication between the teacher and the student for feedback. 

Using MusicCritic the teachers can easily analyze and assess student performances in various dimensions (intonation, rhythm, harmonic properties). MusicCritic provides flexible ways to create and asses tailored exercises. It supports rubrics and it can be personalized by the teachers. 

Based on advances achieved in recent research projects of the MTG on culture-specific music analysis (ex:CompMusic), MusicCritic provides technologies for supporting courses for different music traditions like Hindustani, Carnatic, Turkish makam, Beijing Opera as well as Western music genres like pop and jazz. 

MusicCritic is designed in close collaboration with partners including MOOC platforms and content providers for online music education. With MusicCritic, we push the boundaries of technology to overcome the obstacle of physical distance (between the teacher and the student) and the massive demand in online music learning. 

Technology description

MusicCritic, using a Web API, acts as an external music assessment tool via the Learning Tools Interoperability (LTI) standard, thus able to communicate with any Learning Management System (LMS), including MOOC platforms.

The basic workflow is (1) student records an exercise and submits it to the online platform; (2) the online platform sends the recording to the MusicCritic server where it is evaluated under the optional control of the teacher; (3) the outcome of the assessment, which includes the performing grade and the visualization feedback, is sent back to the online platform where the student can see it. This feedback serves as an objective performing reference that should help teachers and students better identify the learning problems.
 

MusicCritic includes four major components, two running on the client platform (LMS client) and two running on our servers. A part from these, there are the components with which the teachers prepare the actual exercises which are not shown in the diagram.

  1. Play: This is the interface embedded in the LMS client which allows the student to record and submit the exercises.
     
  2. Analysis: This is the component in our server which analyzes the recording submitted by the student and extract meaningful musical features.
     
  3. Assessment: This is the component in our server to compare the student exercises with the reference exercises and the established rubric of the teacher that returns the detailed evaluation of the exercises.
     
  4. Feedback: This is the interface embedded in the LMS client which allows the student to see the feedback given by the assessment component.

Applications

MusicCritic is being used to support online music education to help evaluate the exercises submitted by the students. Other applications can also be supported.

Benefits

MusicCritic technologies are ready to be used and are available as a software service that uses an interface standard (Learning Tools Interoperability) which is being supported by all the known Learning Management Systems and MOOC platforms. Behind these technologies there is a solid research and development support of the MTG team.
