Since this project's theme was given quite clear---to create own "instruments" and perform it in front of the rest of the class. Our group could already see how most of other teams will play their instruments: set them up in the studio and just perform it live. We know that we probably will not be able to create unique instruments in this short period, so we starting putting some effort working on the idea for our presentation performance.
In the final presentation, we didn't play the instruments live, we pre-recorded the sounds from each instrument and played the recorded music while we walk through them, the closer you walk towards an instrument, the sound of that instrument will get louder. It allows the audiences to listen to the sound of every instrument, and also have a sense of what will the combination of these sounds be.
