What is controlling tones?
A typically manual control that allows a listener to change the radio's high, low, and intermediate frequencies' relative amplitudes. Equalization controls, or EQ for short, are the common name for the tone controls on sound mixers. Bass, middle, and treble settings would be found on a mixer with a three-band EQ.
This implies that multiple musical parts, and ultimately a full musical composition, are created using different values, or series. Arnold Schoenberg invented this technique in the 1920s, while others refined it in the years that followed.
