Issues:
1. Getting rid of the froggy artifact on the Lent's formant preserved pitch shifting algorithm
2. Technique for capturing the tilt signal of musical instruments using light sensor

Week 1.

• Short introduction about issues which I'm planning to do

Week 2.

• Demonstration of froggy artifact on the Lent's algorithm
• Idea step 1: extract the main three formant frequency and apply three one-pole filter
• Idea step 2: downsample the signal on the frequency domain
• Idea step 3: apply three one-zero filter for the formant envelop

Week 3.

• Explanation of the concept about capturing and using the tilt signal as a musical expression
• Overview of the technique for using the light sensor as a determinator of tilting

Week 4.

• Reading the paper which treats the instrument player's gesture
• "Vines, B., Wanderley, M., Krumhansl, C., Nuzzo, R. & Levitan, D. (in press). Performance gestures of musicians: What structural and emotional information do they convey? In the Proceedings of the 5th International Workshop on Gesture and Sign Language based Human-Computer Interaction, Genova, Italy."

Week 5.

• Preliminary experiment on photosensor's sensitivity
• Experiment design
