For electronic organ left hand and rotating hair, the more complete the better, thank you!
Electronic left hand can be divided into single-fingered chords and multi-fingered chords, which can be selected by oneself before playing music. When playing a single-fingered chord, just press one note and the whole chord will be played automatically. Let's take C major and A minor as examples. For example:

c

Chord, composed of 1(duo)

3 miles

5(sol), play when you play.

1

Yes, the d chord is composed of

2(

rue

)

4(

The fourth note of the major scale

)

6(

The sixth note of a diatonic scale.

), just press it when you play.

2

Do it. Multi-fingered chords should play three notes at the same time, for example:

Hold down the c chord at the same time.

1

three

five

Three notes, hold down the d chord.

2

four

six

, and so on.

How to match chords?

This involves the knowledge of music theory and acoustics. Before playing, it is necessary to analyze the mode of the song, whether it is major or minor.

How to distinguish the big and small modes of songs?

Major-mode songs usually end with notes.

. Major mode songs are mainly major triads. Minor songs are dominated by minor chords. Major triad (also called the tonic chord) has: C.

) is a minus triad. The main harmonic vocabulary of big mode songs: c-f-g-c.

c——f

c——g

f——c

g——c

This is the most basic series of big mode songs and chords (equivalent to mathematical formulas in mathematics), and chords must be matched according to these formulas. In addition, you can add some minor chords, such as C-D-G-C, C-A-F-G-C.

、c——a——f——d——g——c、c——e——f-c

c——e——a——d——g——c、c——a——f——d——g——c

Wait a minute. Harmonic vocabulary in minor (now minor harmony is the main chord, major triad is the minor chord, and vice versa when the song is in major mode): A-D-E-A, just like major mode, you can also add some minor chords to this harmonic vocabulary, such as A-F-D-G-E-A.

a——d——g——c——f——g——e——a

Wait, there are many methods, which can't be explained clearly in one or two sentences. For details, please read the knowledge of music theory, Knowledge of Music Theory.
