In the piano, how do you calculate the octave of the left hand?

From a scientific point of view: in **, two notes of the same name in adjacent groups, including varying scales, are called octaves. Octaves include pure octaves such as c-c, d-d, minus octaves such as b1-bb, e1-be and increased octaves such as f-f, c-c.

An octave with a note number of 6 is a pure octave, and an octave with a note of 5 and 1/2/2 is a minus octave.

An octave of 6 and 1/2 is an octave. On the piano, the lowest and highest notes are a* and g7 respectively

So the arrangement looks like this: c7d7

e7f7g7

-High) c6d6e6

f6g6a6b6

c5d5e5f5

g5a5b5c4

d4e4f4g4

a4b4c3d3

e3f3g3a3

b3c2d2e2

f2g2a2b2

c1d1e1f1

1 above g1a1b1 is the lowest, and 7 is the highest. Layman's explanation: Octave refers to the interval relationship, to put it simply, you sing 1

1, (Note: 1234567 corresponding to the sound name is cdefgab), the first 1 is the lower octave of the last 1, the last 1 is the upper octave of the first 1, and the other sounds are the same.

ps: The octave dol of the left hand is the lower octave of the right hand plus a line of dol, in short, the tone is the same, the notes are written differently, for the convenience you can see it as the tone of the right hand, but remember that the notes are written differently.

Fingers can span up to 1 octave.

The greater the distance between the fingers and the fingers, the greater the span, the more conducive to playing the difficult **, generally the span between the index finger and the middle finger is very good, the middle finger and the ring finger.

The span between is not good, and intensive training is required.

Finger exercises: 1. Hang your hand in the air to relax your hand, and the second root of the big finger should be relaxed and prominent, and then, let the big finger gently move up and down, and the second root should be prominent. Note that the big finger should be done independently, and the other fingers and hand size should not be affected, and it should be done relaxed.

2. To do exercises on the piano, move the exercises done in the air to the piano, first gently lift your fingers, and gently lower the keys slowly. Pay attention to relaxation and independence. Pay attention to the shape of your hands. Fingers can be prepared without one finger with one click.

3. On the basis of the second article, do the quick touch of the big finger to practice, but also to raise the finger lightly, and then quickly lower the key. The power should not be too great, relax quickly after the sound, the hand shape should be in a good state, and the lower key must be agile.

Only the right hand needs to ascend one octave.

The upper octave (or lower octave) notation is in principle used only for one line of treble (or bass) clef. The treble clef requires only the right hand to raise an octave (i.e., move up from small word group 2 to small word group 3); Don't move your left hand, just play it according to the position of the score (small print 1 group).

The treble clef is the G clef (GCLEF) recorded on the second line of the staff, which designates the position of the G note, indicating that the second line pitch in the staff is G1, which is suitable for the treble area. It is the symbol in ** that indicates the pitch location.

However, the treble clef cannot be equated with the g clef. Because, when the G clef is written on the first line of the staff, it cannot be called a treble clef, but should be called an "ancient French violin clef".

In the ancient West, the earliest G clef was only written on the first line of the staff with an English lowercase g, not the one we are familiar with now, but because it was only made for the violin score in the orchestra at the beginning, in order to make it easy for the violinist to see clearly in the score when playing, the English round character lowercase "g" was deliberately extended upwards to make it look like a violin's bow.

An octave higher is to count 8 keys to the right based on the note you are playing now.

For example, if you play the do now, you want to play the next do on the right, and the do after 8 keys

How do you mean to play an octave?

In fact, the main thing is to work hard, and you can also pull your fingers when you have nothing to do.

Just count 7 notes to the right of the note you want to play.

It's the octave closest to the **c, the closest treble octave.

Uh....In fact, playing the piano is very hard, but there are many benefits, you can exercise your fingers flexibly, and you can also strengthen your brain, but to be honest, not everyone can play the piano, you do have to have a little talent, of course, you must have a relatively high comprehension of **, as for the octave....Oh, in fact, it's nothing, if you practice your fingers more, you'll be flexible, if you don't practice for a long time, your hands will become stiff, and you probably won't be able to cross it...But if you really like it, stick to it, and you will definitely succeed!

The finger span is the distance between the fingers from the palm joint to open the fingers, the greater the distance between the fingers and the fingers, the larger the span, the more conducive to playing the high difficulty**, the general span between the index finger and the middle finger is very good, the span between the middle finger and the ring finger is not good, and intensive training is required. . . The middle finger (3 fingers) is the longest and is located in the middle of the hand, so it has a dominant position, so it has better flexibility and can also support the strength of the arm;

The index finger (2 fingers) is an independent and flexible finger, but it is often not very obedient, like a mischievous child;

The ring finger (4 fingers), because it is physiologically implicated with the middle finger, has poor independence and weak strength, and is a more troublesome finger that requires special "care" to be able to sit on an equal footing with other fingers;

The little finger (5 fingers) is the thinnest, its own strength is small, when learning to play the piano for the first time, it is often unable to stand and like to lie down, but it has to play a particularly important role in playing, so it needs to be strengthened; The thumb is the most special, distinctive finger, it has only two joints, one less than the other fingers, it is the thickest and shortest, like a little chubby, a little stupid, but the most powerful, down-to-earth only finger that can walk sideways, and it is to touch the keys with the side, not with the fingertips like other fingers.

Based on the above analysis, we can see that each finger has its strengths and weaknesses, as well as weaknesses and difficulties, which brings a variety of different topics and tasks to our technical training.

3 fingers is the most worry-free, and 2 fingers should be controlled a little, and he is easy to do. The 4 fingers are like a frail child in the family, you need to pay more attention and do more exercises to make it support like other fingers, and not let it slip through (when playing 3, 4, 5 fingers), but never force it and try to make it independent. Schumann, the famous German Romantic composer, lacked scientific knowledge and did wrong exercises.

used a mechanical device to pull his four fingers, and as a result, he completely broke his tendons, and had to give up his dream of being a pianist. For beginners, first of all, it is required to play with 5 fingers standing, not lying down, and the metacarpal joint should be prominent. The most peculiar is the thumb problem, which is often not valued in the learning process.

Some children even play with the first joint, and it is very heavy, especially when playing the scale.

1 octave bar! I'm now at Level 2!

The piano octave is practiced like this:

Place your forearm flat on the number ridge so that your forearm + hand = a straight line.

Imagine a woodpecker pecking at a tree; Light and stable at the same time.

Apply the woodpecker tree to your arms, your wrists, your palms.

To elaborate:

The arms are imagined to be the body of a woodpecker, the wrists are to be the neck of a woodpecker, and the hands are to be imagined to be the head of a woodpecker.

When you associate your body with a woodpecker, your arms, wrists, and palms will probably look like this: the arms do not move, keep in a straight line, basically parallel to the ground; Move your wrists up and down, but not stiff and relaxed.

Tell yourself to relax, relax. With the palm open, the distance between the 1st and 5th fingers is fixed at 8 degrees, and the wrist drives you up and down to hit the keyboard at close range.

1.When touching the keys, the palm, wrist and forearm should be roughly in a straight line and roughly parallel to the keyboard surface. If the wrist is bent and the forearm is higher than the palm, and the sound is played at a normal or weak volume, the sound of the pop-up must be light and floating.

2.Play the general volume octave, and the forearm should be stable. The whole hand should move up and down with the wrist as the axis, and the size of the action depends on the strength of the playing volume.

However, when performing basic octave exercises, especially when practicing octaves for the first time, the larger the range of movements, the better, so as to increase the amount of movement and enhance the effect of the exercise.

3.Play the general volume octave, with the wrist as the main force point. The wrist should be both hard and relaxed. During the playing, it is necessary to adjust the contradiction between the two parts of the same part at any time to make it coordinated and unified.

If there is more exertion and insufficient relaxation, the movement must be stiff, the pronunciation is sharp and hard, and the arm is too soreness to play for a long time; Contrarily. If there is more relaxation and insufficient force, the fixed movement is loose, the pronunciation is blurred, and the arm is out of control and throws and beats randomly.

When the wrist exerts force, it is necessary to use loose and natural dexterity, not stiff and stiff clumsiness, especially to give full play to the inherent elasticity of the wrist itself.
