As an auxiliary tool in Physics teaching, the utilization of analytical programming and multimedia facilities of the symbolic computing software Mathematica is shown. It is possible to verify the frequency ratios in a musical scale and the beat effect by mathematical analysis and audible reproduction by the computer. For illustrative and pedagogical purposes, sound effects commonly used by musicians, such as Tremolo, Phaser and Auto-Wah are simulated. A simplified mathematical model is defined for them using a standard sound wave whose parameters were experimentally obtained. The possibility of self-teaching is evident.
