Most musical sounds follow a sinusoidal pattern.
That is, if graphed the are variations of sine or cosine curves
the frequency affects the pitch, the greater the frequency the higher the pitch
the amplitude affects the intensity , again, the greater the amplitude of the wave, the louder the sound
the variation of the sinusoidal curve affects the tonal quality of the sound.
For example a certain note played on a violin or a flute may have the same pitch (frequency), but they sound different.
