The method of judging the sound zone on the electronic keyboard is as follows:

1. First, you need to have a general understanding of the sound zone: the keys are arranged in the order of the high and low notes. The bass range is on the left, the midrange is in the middle, and the treble range is on the right.

2. Starting from middle C, the position order of the 1-i sounds on the keyboard is: 1, 2, 3, 4, 5, 6, 7, i-*** eight white keys, It’s called the key of C, and you can also use C, D, E, F, G, A, B, and C instead. The arrangement of the C scale is five whole steps and two semitones. That means a semitone).

3. Between the whole tones 1 and 2, there is the black key sound 1, also called b2, which is pronounced "rising 1" and "flatting 2". It is half a tone higher than 1 and half a tone lower than 2; between the whole tones 2 and 3, there is the black key sound 2, also called b3. It's a half step higher than 2 and every step lower than 3. The same can be said for other sound areas, and each adjacent white key has this semitone relationship.

4. In addition, there are no black keys between 3 and 4, and between 7 and i, and the relationship between them is also a semitone relationship. In this way, between 1-i, one *** includes 12 semitones. This semitone is the smallest pitch distance in music. Therefore, the sum of two semitones equals a whole tone.

5. On the electronic keyboard, the C major scale (a major scale with C as the tonic 1) is all played with white keys. All other major scales use black keys, it's just a matter of quantity. Therefore, the C major scale is also called the "natural major scale".

Extended information:

1. The sound area is part of the sound range. Treble, midrange, and bass are collectively called sound zones.

2. The vocal range is part of the vocal range. According to the different pitches, it can be divided into three parts: treble area, midrange area and bass area.

3. The group of small characters, one group of small characters, and the group of two small characters constitute the mid-range area; the group of three groups of small characters, the group of four groups of small characters, and the group of five small characters constitute the high-pitched area; the group of large characters, one group of large characters, and the group of two large characters constitute the high-pitched area Bass area.

4. The place in the mixer where the sound zone is adjusted is called the equalizer.
