Each chord has its own tone sandhi, but usually, the left and right automatic accompaniment of the electronic organ can't recognize the tone sandhi, so your left and right accompaniment can play any tone sandhi of a chord, and the final effect is the same, such as C major. If you play any one of the three, the final effect is

In the automatic chord accompaniment of electronic organ, there are several different playing methods, which are mainly divided into single-fingered chord and multi-fingered chord. The former is a fast playing method, which is easy to learn. For example, in C major, you only need to press a key of the C note, without pressing every note in the chord. The latter needs to be played according to the real sound contained in the chord. Although relatively complex, it can accommodate relatively more chord types. ?

Extended data

On the electronic organ, the right hand plays the melody and the left hand plays the accompaniment, that is, the chord is played. There are two ways:

① Automatic accompaniment

The simplest is the one-finger chord. Press a white key and major triad will appear. Press a white key and the adjacent black keys (refer to the manual of the electronic organ) will play a chord. Its rhythm and mode (sound type) are selected by the rhythm type button;

More complicated is the multi-fingered chord: the name of the chord is decided by the player himself, but the rhythm and mode (sound type) are still selected by the rhythm button;

② Manual accompaniment. This is exactly the same as the requirements on the piano. You must play different chords and rhythms by yourself. This is an advanced technology that only more experienced players can operate.
