Cajun accordion

A Cajun accordion (in Cajun French: accordéon ), also known as a squeezebox, is single-row diatonic button accordion used for playing Cajun and Creole music.

History
Many different accordions were developed in Europe throughout the 19th century, and exported worldwide. Although accordions are documented in South Louisiana as early as the mid-century, early models would not have caught on with Cajun musicians due to their tuning in A or F and hence the incompatibility with the fiddle. Accordions were brought to Acadiana in the 1890s and became popular by the early 1900s (decade), though it was initially an unaccompanied solo instrument. Popular brands were "Monarch" and "Sterling" in addition to Hohner. The accordion became more widely adopted during the 1920's as models tuned to C and D appeared, and accordions were able to play with fiddles.

The accordion fell out of favor in the 1930's, as Anglophone country music and Western swing spread into the region, and amplification allowed string bands to project more sound, first utilized by the Hackberry Ramblers. However, this trend reversed after World War II, when the accordion became popular in Cajun music once again, exemplified by Iry LeJeune.

Many of the German factories producing diatonic accordions for the United States market were destroyed during World War II. As a result, some Cajuns, such as Sidney Brown, began producing their own instruments, based on the popular one-row German accordions but with modifications to suit the nuances of the Cajun playing style. Since the end of World War II, there has been a surge in the number of Cajun accordion makers in Louisiana, as well as several in Texas. While early-postwar accordion builders had to rely on parts salvaged from older accordions and Hohners, since about 1980 builders tend to use fine imported bellows, reeds, and woods.

Construction
The Cajun accordion is generally defined as a single-row diatonic accordion, as compared to multiple-row instruments commonly used in Irish, Italian, polka, and other styles of music. The Cajun accordion has four reed ranks, i.e., four reeds for each melody button, and each reed bank is controlled by a corresponding stop or knob on the top of the instrument. The four reed banks are tuned in octaves; one at a low octave, two at a middle octave, and one at a high octave. Most Cajun, but not zydeco, accordionists prefer "dry" tuning, meaning that the two middle-octave reeds are tuned to precisely the same pitch. ("Wet" tuning, by contrast, creates a tremolo effect by offsetting one of the reeds' tuning slightly.)

The standard number of melody buttons is ten, with two buttons on the left-hand side: one for the bass note and one for the chord. The tonic note and major chord of the key play on when the bellows are pushed, and the dominant note and major chord when pulled (for instance, C major and G major respectively in the key of C).

Visually, the Cajun accordion typically displays its treble flaps rather than obscuring them behind a grill, as is common with many other accordions. Spoon-shaped levers found on the bass side of German accordions are also replaced with buttons. Inlays, or a solid black finish (in homage to Monarch and Sterling), are popular.

Louisiana-constructed accordions are usually built in small backyard shops like Marc Savoy's Acadian brand and Larry Miller's Bon Cajun brand. Clarence "Junior" Martin of Lafayette Louisiana is a Master Craftsman who also builds accordions in his shop.

Characteristics
The accordion was favored for adoption by Cajun musicians due to how loud it was, unamplified, in noisy dance halls; its ability to stay in tune; and its durability.

The most common tuning utilized is the key of C, although the key of D is also relatively common. Some rarer accordions are constructed in the key of B flat. Cajun accordions are traditionally tuned to a Just Intonation.

Notable players
Although the instrument is called a Cajun accordion, both zydeco and creole musicians play the Cajun accordion with a zydeco and creole sound respectively. Each musician below is considered important in influencing accordion technique and image.
