About Real Free-Reed Aerophone Instruments

Reed Organ: A reed organ, also called parlor organ, pump organ, cabinet organ, cottage organ, is an organ that generates its sounds using free metal reeds. Smaller, cheaper and more portable than pipe organs, reed organs were widely used in smaller churches and in private homes in the 19th century, but their volume and tonal range are limited, and they were generally confined to one or two manuals, with pedalboards being extremely rare.

Harmonium: A harmonium is a free-standing keyboard instrument similar to a reed organ. Sound is produced by air, supplied by foot-operated or hand-operated bellows, being blown through sets of free reeds, resulting in a sound similar to that of an accordion.

Bandoneon: The bandoneón is a type of concertina particularly popular in Argentina. It plays an essential role in the orquesta tipica, the tango orchestra. The bandoneón, called bandonion by its German inventor, Heinrich Band (1821–1860), was originally intended as an instrument for religious music and the popular music of the day, in contrast to its predecessor, the German concertina (or Konzertina), considered to be a folk instrument by some modern authors. German sailors and Italian season workers and emigrants brought the instrument with them to Argentina in the late nineteenth century, where it was incorporated into the local music, such as tango.

Accordion: The accordion is a box-shaped musical instrument of the bellows-driven free-reed aerophone family, sometimes referred to as a squeezebox. A person who plays the accordion is called an accordionist. It is played by compressing or expanding a bellows whilst pressing buttons or keys, causing valves, called pallets, to open, which allow air to flow across strips of brass or steel, called reeds, that vibrate to produce sound inside the body.

Flutina: The flutina is an early precursor to the diatonic button accordion, having one or two rows of treble buttons, which are configured to have the tonic of the scale, on the "draw" of the bellows. There is usually no bass keyboard: the left hand operates an air valve (silent except for the rush of air). A rocker switch, called a "bascule d'harmonie" is in the front of the keyboard. When this switch is thumb activated, it would open up a pallet (a pad that covers a tone hole, at the other end of the key button(s), (see photo) for a simple Tonic/Dominant drone: Tonic on the draw and Dominant on the press, e.g. Tonic notes C/g, and Dominant G/d, without any major or minor thirds.

Harmonica: The harmonica, also called harp, French harp, Blues harp, and mouth organ, is a free reed wind instrument used primarily in blues and American folk music, jazz, country music, and rock and roll. It is played by blowing air into it or drawing air out by placing lips over individual holes (reed chambers) or multiple holes. The pressure caused by blowing or drawing air into the reed chambers causes a reed or multiple reeds to vibrate up and down creating sound. Each chamber has multiple, variable-tuned brass or bronze reeds, which are secured at one end and loose on the other end, with the loose end vibrating and creating sound.
