The theoretical opposite of subtractive synthesis, Additive Synthesis constructs sounds from the bottom up with multiple sine wave generators.  To understand Additive Synthesis, it is important to have a grasp on the Fourier series, which states that any wave (in this case a sound wave) can be made by combining a particular number of sine waves at varying frequencies and amplitudes.  The combination of multiple sine waves generates tones infinitisemally close to other wave types (sine, square, sawtooth, and noise).
