A button accordion is a type of accordion made with a series of button keys instead of piano-style keys. Like any accordion, it is played by expanding and compressing a bellows to generate airflow across the keyboard controls or reeds. It comes in different tuning systems, actions, and constructions.
Types of Button Accordions
Kinds of Button Accordions include the following:
Diatonic button accordion
The diatonic button accordion is made with a melody-sized keyboard limited to a small number of keys with notes limited to the diatonic scale.
It has a bass side containing the principal chords and root notes.
It is usually bisonoric, which means that each button can produce two notes--one note when the bellows is compressed and another when it is expanded.
Chromatic button accordion
The chromatic button accordion is made with a melody-sized keyboard with uniform rows of buttons arranged in a way that the pitch increases chromatically across diagonals.
It has a bass side keyboard that uses the Stradella system or a converter system.
Choosing Button Accordions (Buying tips)
Type: Choose a chromatic button accordion for playing classical music because it produces a greater range of sound than a piano keyboard configuration. Choose a diatonic button accordion for playing folk music.
