Early predecessors
CONCERTINA
• Buttons produce only single
notes (rather than chords)
English concertina
(1830s) by
Wheatstone,
(shows exterior airvalves, concealed in
later models)
FLUTINA
• Early precursor to the
diatonic button accordion
The first accordion
• Patented in Vienna in 1829 by Cyril
Demian, together with his sons
Guido and Karl
• Two key-activated single-action
harmonicas connected by bellows.
• Diatonic accordion: produced one
set of pitches when pulling, and a
different one when pushing the
bellows
• Some buttons of the left side were able to produce full triads,
hence the name “accordion” (akkord in German and accord in
French are equivalent to the word chord in English).

The bayan

Chromatic button accordion: the melody-side keyboard consists of
uniform rows of buttons arranged so that the pitch increases chromatically
along diagonals.

Russian origin.

Increased range.


3 to 5 rows of treble buttons. In a 5 row chromatic, two additional rows
repeat the first 2 rows to facilitate options in fingering.
Chromatic button accordions are preferred by many classical music
performers: the treble keyboard with diagonally arranged buttons allows a
greater range than a piano keyboard configuration

Treble keyboard action
When a button on the
bayan is depressed, it
raises the palette and
enables air to pass
through the reed block
to activate the
corresponding reed
