Lab 4 Partials, overtones, and waveforms Strings, tubes and other objects used to make musical sounds vibrate in more than one mode at a time. Each mode can be represented by a sine wave with a given frequency, amplitude and phase. Normally, the various modes are integer (i.e. whole-numbered) multiples of a primary frequency. This primary frequency is the pitch of the note. The various modes of vibration are called partials , or alternatively (and confusingly, at first) a fundamental and its overtones . When sine-waves representing partials are added together, the sum retains the pitch of the fundamental, but the tone-color or timbre (rhymes with “amber”) changes according to the amplitude and frequency of the partials. Download and unzip “Partials.pd.zip” Open “Partials.pd” To the right of the START button is a number box marked “Key.” This number is a MIDI key number (#72 is Middle C.) If you drag the key number up or down you see it converted to a frequency in the number box below the “mtof” converter object. This
