Sonification: Auditory Graphs

Map: Pitch (frequency) -> ordinate (y) vs Time -> abscicca (x)
Hear points (1,1) and (2,4):
Hear a straight line
Hard to distinguish y = x from y=x²
Add "drum" beat:
- slope dy/dx : number of drum beats
- curvature d²y/dx²: pitch of beat
y=x² (+ curvature, low f beat)
y=sqrt(x) (- curvature, high f beat)
