• It illustrates the sine wave of a sound wave with animated screens, in order to explain how a string or column of air vibrates to create musical sounds. It examines Mersennes Laws which determine the pitch of a vibrating string.
• It explains Simple Harmonic Motion by means of an animated rotating radius subtended onto a Cartesian graph. 
• It explains the natural harmonics and overtones of a note, with reference to the simple frequency ratios that make a sound or an interval pleasing to the ear. 
• It illustrates musical applications for the polynomial curves (ellipses, parabolas and circles), for straight line and reciprocal equations, for logarithmic equations, as well as for the trigonometrical equations. 
• It uses statistical bar charts to analyse the tonal and rhythmic characteristics of any piece of music in the Musical Discovery database.
