Abstract

The invention relates to an accordion with a treble part which is provided with a keyboard, the keys of which are connected via clavis levers to flaps for soundholes which are assigned tuning reeds which can be set in vibration by playing wind and are supported by reed boards. In order to be able to play polyphonically in a simple manner, it is envisaged that each flap is assigned three tuning reeds which respond to pushing playing wind and three which respond to pulling playing wind, which in each case produce a tonic of a key and the associated thirds and fifths, the keys being arranged in a diatonic progression and the tonics being producible in a diatonic progression alternately by tuning reeds which respond to pushing playing wind and pulling playing wind.

Description

The invention relates to an accordion according to the preamble of Claim 1; see. the company script: all about repairs by accordions Melodicas, harmonica, Matth. Hohner AG, Trossingen, 1978, pp. 8-27.

Typically, an accordion uses a keyboard that is designed as a button keyboard or keyboard, by pressing a key, depending on the draft or pressure wind, a corresponding voice tongue is vibrated, the associated flap through the Button operation has been opened. This can also be used for multi-course Playing multiple reeds at the same time however, it is always the same tone in different Octaves. Playing with such an instrument is difficult too learn, especially when playing chords, pressing a wrong one Button sounds wrong.

The object of the invention is an accordion according to the preamble of claim 1 to create, which makes it easy in a short time To play pieces in harmony.

This task is performed according to the characteristic part of the To spell 1 solved.

This ensures that pressing a treble button three-part melody chord sounds when the bellows is pulled or pressed, by directing the game air over several reeds. Every stone covers a corresponding number of tone holes. In particular, by actuation a slider also creates a four-part melody chord.

The accordion is in a certain key, for example C- Major, tuned, and by means of a key can be conveniently one  generate a reduced seventh chord, this key next to the key for arranged the third and fifth chord of the same root is so that there is no recourse to playing the diminished seventh chord necessary is.

On the bass side there are two keys for four Basic bass and two keys for four accompanying chords harmoniously match the Arranged treble. This means that even unintentional "Ver player "sound good and not wrong.

If necessary, the accordion can also be used to play in at least two keys can be set up, with corresponding sliders provided to select the desired key.

Further embodiments of the invention are the following Be the spelling and the subclaims.

The invention is based on the in Ab Formations illustrated embodiments explained in more detail.

Fig. 1 shows the chord progression for a deon chord tuned in C major.

Fig. 2 shows a front view of the bass part of an accordion.

Fig. 3 shows schematically in section the treble part of an accordion playable in several keys.

Fig. 1 shows two reeds 1, 2 for the treble part of an Ak accordion seen from its front, which are each provided with two rows of tone holes 3 and are mounted such that each of the four tone holes 3 located one above the other by means of a flap are closable, the flap being connected to a key of the keyboard via a corresponding piano lever. On the back of the reeds 1, 2 these have corresponding chambers, which are closed by reed plates, which carry ventilated reeds that respond to pressure wind or draft wind reeds. The tuning of the reeds is shown in Fig. 1, in the first row there are the reeds for the basic tones (primes), in the second row the reeds for the sixth, which can be switched on via a slide 4 , in the third row the fifths and in the fourth row the thirds. In each case, the tones of the reeds responding to the pressure play wind to the left of the horizontal bar and the reeds responding to the tensile wind to the right of the cross bar are indicated.

When you press the fourth key of the treble part in this  If a total of ten keys is included, the min played the seventh chord in C major while pressing the third Key the normal prime, third and fifth (possibly sixth) comprehensive Chord with the root note g sounds. A corresponding arrangement is for g ′ ′ met. By pressing keys for chords to the same root Multi-choir can be played in different octaves.

As is apparent from Fig. 2, the bass part 5, which is connected to the upright part via a bellows Dis 6, four keys 7 are provided. Two keys are used to play four basic basses C / G and G / F, if necessary double-chorus with c / g and g / f, while two other keys are used to play four chords g / gc ′ / he ′ / d ′ and g / fh / ad ′ / c ′ serve.

In addition, a button 8 for soundless opening or closing of the bellows 6 is provided.

According to FIG. 3, three pairs of pinblocks 1, 2 is provided which in each case a different key are tuned such. B. in C major, G major and F major. On the fingerboard 9 of the treble part 10 of the accordion, keys 11 that can be actuated against a spring preload are provided, which are connected via piano levers 12 with flaps 13 , each of which covers three or four tone holes 3 for playing a three- or four-part chord. By pressing a button 11 all the flaps 13 connected to the respective piano lever 12 are lifted off and open the corresponding tone holes 3 for the corresponding chords in the respective key. So that only one key is played, corresponding key sliders 14 are provided which can close the tone holes 3 of those pairs of reeds 1, 2 of the key not to be played. Here, too, the sixth row can optionally be switched via a slide corresponding to slide 4 .

The piano levers 12 each have in a plane to each other (by 90 °) angularly offset, each have a flap 13 carrying Armab sections 15th
