These days you can now carry all your music on your phone or stream the music via mobile internet. What actually preceded getting music in this compact digital form? This is an entire process with a key role for mathematics. To describe the frequency and intensity of tones, you use trigonometric functions such as the sine and the cosine. For music you then need a sum of a great many of these functions.
The next step is to digitalise it as efficiently as possible, in other words describing with numbers, without affecting the quality of the music. These data allow you to edit the sound, by adding echoes for example, or linking an orchestral part and a vocal part, removing static and much more.
