| Description: |
The ‘Tartini’ project at the University of Otago aims to use the computer as a practical tool for singers and instrumentalists. Sound played into the system, a pc with a microphone attached to it running the ‘Tartini’ software, is analyzed fast enough to create useful feedback for teaching or, at a higher level, for practicing musicians to refine their technique. Central to this analysis is the accurate determination of musical pitch.
Another aspect is the analysis of notes that are being played with vibrato, a fast modulation in pitch that is typically used to add expression and vocal-like qualities to instrumental notes. The main components of a pitch vibrato are: speed (or frequency), width (or amplitude) and form (or shape of the vibrato).
One of the goals of this assignment is to automatically analyze vibrato notes, possibly in real-time, and give useful feedback to the musician who is playing the notes. Useful feedback could consist of the components mentioned above. This information has to be displayed in a meaningful way for the musician.
Some professional musicians from the Department of Music are willing to test and comment on the project. Also, there are a lot of prerecorded sound files that could be used for testing.
