Mathematically, the simplest wave is a sinusoidal plane wave in which at any point the field experiences simple harmonic motion at one frequency. In linear media, complicated waves can generally be decomposed as the sum of many sinusoidal plane waves having different directions of propagation and/or different frequencies.

The motion of material around the center indicates that Sagittarius A* harbors a massive, compact object. [188] This concentration of mass is best explained as a supermassive black hole [ h ] [ 181 ] [ 189 ] (SMBH) with an estimated mass of 4.1–4.5 million times the mass of the Sun . [ 189 ]
The harmonic timbre of the output, not being a pure tone, was an important feature of the theremin. [20] Theremin's original design included audio frequency series/parallel LC formant filters as well as a 3-winding variable-saturation transformer to control or induce harmonics in the audio output.
A guitarist performing a C chord with G bass. In Western music theory, a chord is a group [a] of notes played together for their harmonic consonance or dissonance.The most basic type of chord is a triad, so called because it consists of three distinct notes: the root note along with intervals of a third and a fifth above the root note.
