... the purposes of the VHVCoLab, a 'server version' of the GJT application was developed and it is employed to generate the musical notes that correspond to the chord symbols of a given jazz standard. For the purposes of music education, both chords and generated drums, bass, and piano part are rendered to the online interface, as in the example of Fig. 5. The process of converting jazz standards to three-staff notation and sound font rendering is described in more detail in ...

... awareness involves informing all session participants for the execution of a user action. Certain user actions were chosen to be made aware to the participants of a session. These are 'note selection, 'multiple note selection', 'chord edit' and 'add comment'.

For example, when a user chooses to edit the chord, the chord editor of Fig. 6a is replicated on every online ...

If a user disconnects, then their profile icon is shown with a red, as opposed to a green dot. dedicated database is used to make persistent the collaborative exchanges that have taken place during a synchronous session for a specific score of the ODR and a specific course of the LMS. This allows tracing how different courses ...
