Same tone

As Gleichton the button when is diatonic accordion called, produces the same sound in both directions of pull.

The triad tones of the respective key (major triad of the tonic) sound when the diatonic instruments are closed. In the elevator the tones in between (associated dominant seventh chord) sound. Since the 5th note of the scale occurs both in the tonic and in the dominant, this note is built into the middle register both in push and in push because it is easier to play, i.e. it is played with the same button, with the exception of the outer row .

The key (button) sounds monotonous . The remaining keys in the respective row are keys with alternating tones.

The first diatonic instruments did not have buttons with the same tone, as is still the case with many diatonic instruments today ( Vienna model ). The same tone is on level five of the respective diatonic scale. On a C major scale, it is the dominant g that sounds monotonous.

development

At first, some instruments in the third row got the same tone. Today all Styrian harmonicas in the 2nd to 5th row have the same tone. The common tone makes it easier to grasp chord progressions ( cadences ) that have the sequence I, V (degree theory) . Alpine folk music and pop music are strongly influenced by these sequences and harmony patterns.

Another variant is used in Holland, whereby the corresponding reed plate is turned on the sound post. This also leads to the effect that the dominant seventh chord sounds when pulled . In the printing direction, however, you have to switch to the next inner row for tone level five.
