![]() ![]() They play the same notes as the same buttons of the 1st and 2nd rows. Most chromatic accordions have two extra rows located to the left of the main rows. In the "type B" accordion, the "C" is located on the third row from the right. In the "type C" accordion, the middle "C" is on the row furthest to the right. In both types, the further away from the top of the keyboard you go, the higher the notes the closer to the top, the lower. There are two main types of button accordions.

They have either three or five (or very rarely six) diagonally-horizontal rows. This row provides the missing notes and it is also equipped with a unisonoric (producing the same note or tone regardless of the direction of the bellows) button which is a “C” note.A chromatic button accordion is a type of button accordion where the right side keyboard has rows of buttons arranged chromatically.

Diatonic scale played on a piano What does Bisonoric mean?Īny free-reed instrument that produces a different note (sound) depending on the direction of the bellows or airflow through the reeds is considered Bisonoric or diatonic. Musical instruments such as keyboards, pianos, and accordions (buttons on a button accordion) form a diatonic scale. In the UK and Australia, diatonic accordions are referred to as Melodeons whereas, in Ireland, only single-row accordions are referred to as melodeons.ĭiatonic,(also referred to bisonoric when referring to an accordion) in musical theory, refers to a musical scale (major or minor), that comprises intervals of five whole steps and two half steps in an octave. Although they may look the same, diatonic accordions may be called differently in various parts of the world. Let’s acquaint ourselves with the meanings of these terms.ĭiatonic accordions are bisonoric, which means that they produce different tones when bellows are expanded or compressed. When reading about button accordions you will often find that they are described as either diatonic, bisonoric, or chromatic. We’ve devoted a bit more detailed description of every type of button accordion in a separate article you can access by clicking on the names of the accordions described below.
