Chickering & Sons was an American piano manufacturer located in Boston, Massachusetts. The company was founded in 1823 by Jonas Chickering and James Stewart, but the partnership dissolved four years later. By 1830 Jonas Chickering became partners with John Mackay, manufacturing pianos as "Chickering & Company", and later "Chickering & Mackays" until the senior Mackay's death in 1841, and reorganized as "Chickering & Sons" in 1853. Chickering pianos continued to be made until 1983.

The piano is a keyboard instrument that produces sound when its keys are depressed, through engagement of an action whose hammers strike strings. Most pianos have a row of 88 black and white keys, representing each note of the chromatic scale as they repeat throughout the keyboard's span of seven and a quarter octaves. There are 52 white keys, known as “naturals”, and 36 black keys, known as “sharps”. The naturals repeat a pattern of whole steps and half steps unique to any given starting note. These patterns define a diatonic scale. The 36 sharps repeat a pattern of whole steps and minor thirds, which defines a pentatonic scale.
