What instrument family belongs the accordion to?

Answer 1

Free reed instruments
This family of instruments was developed in the early nineteenth century. They all work on the same principle: air is blown across a set of paired metal reeds, causing them to vibrate and produce a particular note. All but the harmonica are powered by bellows pulled in and out by the arms (hence 'squeeze box'). The two reeds of a pair are placed in opposite directions, so each is vibrated by either the press or the draw (in or out) of the bellows. 'Single-action' instruments have the pairs tuned a tone apart, so the one key will produce two adjacent notes depending on whether the player is pressing or drawing. 'Double-action' accordions have the reed pairs tuned in unison, so one key produces one note. The button accordion has a second row of keys, tuned a semitone above the first set, giving a fully chromatic instrument. .
The piano accordion has a piano keyboard on the left and an extensive bass keyboard on the right hand. It is a double-action instrument (same note on press and draw) and much larger than the button accordion. It is most popular in Scotland and is also widely used in central European folk music.

Answer 2

An accordion is a musical instrument of the handheld bellows-driven free reed aerophone family, sometimes referred to as squeezeboxes.

The accordion is played by compression and expansion of a bellows, which generates air flow across reeds; a keyboard controls which reeds receive air flow and therefore the tones produced.
