Chromatic button accordion

The chromatic button accordion ( in the English language: CBA for chromatic button accordion ) is an accordion instrument. The right side is fundamentally different from that of the piano accordion.

Precursor of this instrument was developed in Vienna Schrammelmusik harmonica with the first B- handle assembly on the treble side.

Modern instruments of this kind essentially correspond to the Russian bayan. There are instruments with and without cassotto, an additional resonance chamber in the treble.

For the bass part ( on the left ), there are different constructions, which are also used in modern piano accordion, see bass systems.

Handle systems

It classifies the chromatic button accordion after the arrangement of buttons into two categories, depending on whether the semitone rise from the outside (first row ) to the inside or vice versa. The naming of the systems (C- handle, B-System, G - grip ) are prepared by a tone, which occurs only in the first ( and fourth ) series.

• Found on C -handle instruments ( Italian or Swedish arrangement ) is the C in the first ( and fourth ) series: half steps from outside to inside increasing. With the usual in Finland G -handle instruments tone G is stored in the first ( and fourth ) series. C. Thus, in the third row. Game Technically, the C- handle and the G- grip are very similar, because fingering patterns and relative references of the sounds are the same. The mechanics of the keyboard is completely the same.

• Semitones from the inside out rising: In the B- grip instruments (actually it would have in the German-speaking area "H " handle hot ), also known under the name "Norwegian " arrangement, the H is in the first ( and fourth ) to find number, and the semitone rise from the inside out. This handle system is widespread in Russia, Norway, Serbia and Belgium.

The treble is now mostly built with five rows of buttons, the fourth and fifth row is considered a repetition of the first and second row. White and black buttons corresponding to the white and black keys on the piano. In colored buttons for better orientation are usually the knobs C and F marked (eg with a rough surface ), sometimes C, G and D, or, in analogy to the selected bass buttons, C, E and As. Small instruments sometimes are limited to three rows.

Especially in popular music often to be seen exceptions are C -handle Four Herons in France and B-System - Six herons in the Balkans.

The fourth series of simplified grasping some chords ( which are otherwise uncomfortable especially with C- handle), the fifth row in principle allows the free transposability with the same fingering of passages that would otherwise be played in three rows. A sixth series combines the advantages of both principle. In practice is individually different, the manner in which the rows are actually being used by the players.

Also worth mentioning is that the time is not very common 6 -plus -6- accordion, in which the tones are arranged on two rows, which has the advantage of one-dimensional melody lead with: how the piano - and not, as in the above described knob systems - will be played at 6 -plus -6- accordion a crescendo tone sequence always ascending. However, the advantage of the free transposability is the 6 6- accordion in contrast to the piano also available. 6- plus - 6 system can be constructed as a keyboard. It can also be played on the computer keyboard.

Game practice

Many accordionists playing primarily on the first three rows, the fourth and fifth rows are considered " auxiliary rows ". In the advanced game, however, all rows are equally recorded in order to avoid unfavorable and unergonomic finger positions. Five rows also allow a technique that allows the same grip pattern in all keys, if you limit yourself to three rows. So it is very easy to transpose music tracks. The invariant grip patterns permit the skilled player, a very functional -oriented style of play. For example, a major chord always has the same fingering pattern, no matter what tone it is set up. Also, scales and intervals can always be played with the same fingering patterns.
