In slightly greater detail, an example of sound modelling would be a computer program that simulates the process of a string being plucked, based on the material, length, diameter and tension of the string, and then modifies the result by calculating the resonances and phase cancellations of a soundbox based on its dimensions and materials, area of soundholes etc. It's all a matter of on-the-fly calculations which produce the data for a waveform which can be amplified and heard.

Sampling is much simpler; the sound of a real instrument (e.g. a guitar) is recorded to computer memory and then played back at different speeds to create different notes.

Hope this helps.
