The function of scale practice:

1. Most scales are used by eight fingers of both hands, and practicing scales can train the balance ability of fingers.

2. Scale practice can make you familiar with the phonemes of the fingerboard. All scales consist of 24 major and minor modes, and almost all the European music we contact most belongs to these modes. If you are familiar with the scales, you will be generally familiar with these modes.

3. Actually, music is composed of complete or incomplete scales, especially melodic parts.

4. The scale seems simple, but it is difficult to make it well if it is strictly uniform, fast and grainy.

5. Add different rhythms, accents, and strengths to the scale exercises, and use all imaginable combinations of right fingers (I ask students to practice with any imaginable combination such as im, ia, ma, pi, pm, pa, ich, mch, ach, ami, ima, mia, mai, pima, pami, etc., some of them.

6. Scale exercises play a great role in training the coordination ability of left and right hands.

Personally, I feel that after training the ch finger, the problem that the A finger is difficult to control seems to be solved. In fact, practicing fingers is nothing more than practicing the brain's ability to control fingers. Fingers and ears receive and feed back information, which is transmitted by nerves, and the brain analyzes and judges and issues instructions, and then the nerves transmit it back. The training of control ability is comprehensive, and I don't think we should stop practicing just because we use less ch fingers.

Common shortcomings of scale practice:

1. Incoherence, like playing a cadence.

2. The graininess is poor and vague.

3. Uneven timbre and strength, lack of uniformity.

4. Each finger of the right finger has no independent plucking action, and sometimes one finger brings out another finger.

5. There are too many redundant actions when the left finger moves.

6. Only emphasize the speed, ignoring the sound quality.

7. The left finger on the 456 string can't be straight up and down, and there are too many noises.

8. Lack of musicality and dull expression.

The basic essentials of scale practice:

1. Fingers rise and fall vertically, and the height should not be too high when lifted, and it is appropriate to be about one centimeter.

2. For the sake of coherence, the next finger should be pressed before the previous finger can be lifted.

3. The left hand always keeps an appropriate radian, and you can't lose your shape because of changing strings.

4. The left finger should be perpendicular to the fingerboard as far as possible, and the strings should be pressed with the fingertips.

5. The force should be based on the real strings, not too big. The left finger movement should be coherent, soft and natural.

6. the speed should not be fast, but should be clear, coherent and even, and gradually improve.

7. Pay attention to the sound control when holding the handle high, and don't be "empty". Right refers to proper application of force.

8. It is best to emphasize the lowest and highest notes.

9. Each finger of the right hand must complete each plucking action independently, and it is not allowed to take it "with the trend". Pay attention to the uniformity of tone and tone of adjacent sounds and the uniformity of strength.

1. It's better to practice with different beats and strengths.

second, let's understand what is a scale

scale. A group of musical notes with different heights are arranged in a ladder-like manner according to the law, which is called a scale. The scales prevailing in modern times are divided into two categories, one is natural scale and the other is chromatic scale.

natural scale: there are two kinds, one is major scale and the other is minor scale. A major scale consists of five whole tones and two semitones, one of which is between the third and fourth tones and the other between the seventh and eighth tones. Minor scales can be divided into three forms, with one chromatic position between the second and third and the other between the fifth and sixth, which is called natural minor scales. The semitone position, one between the second and third notes when ascending, one between the seventh and eighth notes, one between the second and third notes when descending, and one between the fifth and sixth notes, is called the melody minor scale. A semitone with a position between the second and third tones and a position between the seventh and eighth tones, and a second interval between the sixth and seventh tones, is called a harmonic minor scale. The first note of the diatonic scale is called the tonic, and the other notes are named around the tonic. The fifth tone above the tonic is called the dominant tone, the fifth tone below the tonic is called the subordinate tone, the third tone above the tonic is called the alto, the third tone below the tonic is called the alto, the second tone above the tonic is called the second dominant tone, and the second tone below the tonic is called the leading tone.

chromatic scale: it consists of twelve chromatic scales with exactly the same distance. There are two kinds of notation, one is called harmony semitone notation, and the other is called arbitrary semitone notation. The former has the same ascending and descending lines, while the latter has different ascending and descending lines.

in addition, there are four tones in ancient Greece, pentatonic scales in China, Japanese and Scottish, church scales, diatonic scales and so on.

Twenty-four fingering combination tables

1234 1243 1324 1342 1423 1432

2134 2143 2314 2341 2413 2431

3124 3142 3214 3241 3412 3421

4123 4132 4213 4213. In the table: 1 stands for index finger, 2 stands for middle finger, 3 stands for ring finger and 4 stands for little finger. In practice, each finger presses a character, and plays from six strings to one string in turn or across strings, and each combination is played six times. The playing speed should be gradually accelerated with the proficiency, and the unskilled fingering combination can be practiced emphatically. Playing at frets 1 to 4 can train the expansion of fingers; Playing at 9 to 12 frets can train the coordination of hands and the playing speed. In addition, you can also practice one by one according to the serial number, and it is appropriate to train for half an hour every day. The key is to persevere.

Personally, I think this kind of exercise is very necessary and practical, and it is a good way for beginners to practice finger flexibility. This is the most basic fingering practice, as well as cross-grade comprehensive combination practice, which is done in the improvement stage. After this pass, you can get twice the result with half the effort by practicing the piano in the future. Come on, I am still practicing this every day.
