From the structural point of view, classical guitar and folk guitar are similar, both of which amplify the vibration and sound of strings through the * * * sound box of the piano body. Please look at the picture below: the classical guitar on the left and the folk guitar with missing horns on the right. Note that from the front, the leftmost chord is the thickest and the rightmost chord is the thinnest. When holding a piano, the thinnest first string is at the bottom, which is the fingerboard. We often say that the first fret refers to the fingerboard above the first fret counted down from the piano pillow. Basic course 2: Playing posture and hand guitar requires that the left and right hands holding the piano are naturally comfortable and relaxed. Sitting posture is the same as standing posture, and the guitar should be close to the body. (1) Sitting style: 1, sitting flat-feet are slightly separated, the concave part of the guitar body is placed on the thigh of the right foot, the piano face is slightly tilted upward, and the upper body is slightly tilted forward. The height of the guitar head should be between the shoulder and the neck. 2. Foot-Tilt-The right leg is tilted on the left leg, and the piano body is placed in the same way as the sitting posture. 3. Footstool style-the right foot or left foot is placed on a low stool about 18 cm high, and the piano body is placed on the right leg or left leg. (2) Standing style: hang the piano around the neck with a piano belt and stand and play the left-handed string pressing key points: 1. Hold your neck gently with your thumb and forefinger, and bend your palm into an arc to move up and down flexibly. 2. Each finger should be as parallel as possible to the goods on the fingerboard. When you press the string, your fingers should stand up as much as possible. Don't touch other strings. Put them near the products, don't press them on the products. Just like when a product has more than two tones, the finger presses the bass string at the low position and the finger presses the treble string at the high position. The names of the two fingers of the left hand hand shape and the right hand shape are basically books. It is no harm for beginners to start practicing based on this standard. When they have a certain foundation, they don't have to follow the tutorial, because guitar is a very personalized instrument, and everyone may have their own differences. For example, many western musicians (especially electric guitarists) don't hold the piano back as high as the center, let alone stand. The hand shape of the left hand does not bend into an arc in some cases. In short, it is right for everyone to take these seemingly prescribed things as a reference. Basic lesson 3: the method of guitar tuning is very important, because friends often ask why it is nice to listen to others playing the piano, but playing the same thing by yourself is not as simple as music, which is caused by inaccurate tuning. Let's look at the tuning method first: the guitar tuning system adopts the twelve-average law (it doesn't matter if you don't know what it means). The tuning method we usually use is called the standard e-key, that is, from the first group of strings to the thinnest string, and the empty string (without pressing the string with the left hand) should have the same pitch as the six keys of the piano, that is, e, a, d, g, b, e 1, which is quite equivalent. Alto 2 5 7, treble 3 guitar empty string pitch So how can we adjust the string? The simplest method is, of course, to compare with the piano or electronic organ, and change the pitch of the empty strings of six strings into the same pitch as the corresponding piano keys. However, some friends may not have a piano or an electronic organ. You can buy a tuning flute, specially designed for guitar. It has six flute holes, corresponding to the pitch of each empty string of the guitar. This thing is the flash under the tuning flute, and it can also help you tune your guitar-online tuning flash. The above methods are actually to play the standard pitch of each empty string with an instrument, and then listen to whether the sound of your piano corresponding to the string is high or low with your ears, and then adjust accordingly. Basic Course 4: Guitar Tuning Methods (Part II) Last time we talked about guitar tuning methods. In this lesson, we will continue to talk about it. Because the tuning of guitar strings is really the most important and distinctive place, freshmen must pay attention to it ... Last class mainly talked about the standards of guitar tuning, and there are still some skills to be found in actual operation. In this lesson, I will tell you all the tuning skills I know. Beginners need to pay attention. Although the tuning software I introduced last class is very easy to use and powerful, it is most basic for a guitarist to tune by listening, because the strings of the guitar need to be re-tuned almost every time before playing, and you don't have a computer or electronic tuner available for each tuning. Anyway, the common method of tuning strings is to use different chords on guitars with high homophones. Look at the picture: the first product is a schematic diagram of the first six products of a guitar fingerboard. The vertical line represents the strings, with the first string (the thinnest one) on the far right and the sixth string (the thickest one) on the far left. The horizontal line represents spun silk, and the top double horizontal line is the piano pillow. Yes, that's the way the guitar stands up. We will see this kind of thing on the chord chart in the future, so I won't say much. There are some letters in this picture, and everyone's music theory here is different, so I won't introduce them here. In short, remember: the distance between two characters connected by dotted lines in the picture should be the same. What do you mean? That is to say, the fifth fret of the sixth string should play the same pitch as the empty string of the fifth string (the left hand does not press the string), the fifth fret of the fifth string and the empty string of the fourth string have the same pitch, while the fourth fret of the third string (note that this is different from others) has the same pitch as the empty string of the second string, and the fifth fret and the first fret of the second string. You got it? In fact, for guitar, as long as the relative interval (pitch) between strings is adjusted, harmonious and beautiful music can be played, and it is not necessary to adjust to the standard pitch. Of course, if multiple instruments are played together, they must be tuned according to certain standards. However, it should be noted that, in fact, in ensemble, one sound of one string is often aligned between the pianos, and the other strings are fixed with equal pitch. The novice said, it still depends on the ears. What if you're not sure? In fact, there are other methods without computer-aided tuning, namely * * * vibration method. I won't explain its principle. If you are interested, read junior high school physics books. The operation method is as follows: Take the adjustment between the sixth string and the fifth string as an example. If it is determined that the sixth string has been tuned, press and hold the fifth fret of the sixth string, and dial the sixth string harder, then observe the vibration of the fifth string (empty string) and adjust the length of the fifth string until the vibration amplitude of the fifth string caused by dialing the sixth string is the largest. Of course, you should at least hear which one is higher and which one is lower when the two strings are very different, otherwise ... I cut the second thick rope twice a day. Ok, let's talk about so much piano tuning. Now that you have honed your instrument, you can start practicing Basic Course 5. How to read the score of guitar? I'll teach you how to learn staff and music from scratch in five minutes-I'll teach you how to know what's under the score. Every book has an introduction, and it is very detailed. I'll pick up one, so novices shouldn't be frightened by terminology. Later I will introduce Guitar Pro, a special software for guitarists to practice/compose music. With this software, you can listen to the effect of playing music while watching. Let's talk about music. We often play folk guitar, especially when playing and singing, because the guitar has six strings. Hehe, of course, many classical and electric piano masters just watch the staff, but we are beginners and have a hobby. This is what the common six-string symbol looks like. Let's look at the left picture first: the "O" on the banjo means the empty string sound (E) when playing the banjo, and the "3" on the banjo means the third fret sound (C) when playing the banjo. The "2" on the four strings means playing the sound (E) on the second fret of the four strings. The three "5s" that appear at the same time in the vertical direction refer to the simultaneous playing of three notes a'(6), two strings and one string on the fifth fret of the three strings. In fact, the gameplay can be fully expressed only by the left picture. But what we often see is the spectrum on the right, that is, the left-hand chord and the right-hand fingering are written separately. Of course, this is to look cool. Hehe, in fact, indicating chords have other uses, but for beginners, it is of course the most important to look cool. Look at this picture like this: first, look at the middle, which is a single chord called C chord. Press the second string L fret with your left index finger, the fourth string 2 fret with your middle finger, the fifth string 3 fret with your ring finger, and then press this C chord. So the chord diagram is a pure left-handed fingering diagram. Look at the picture on the far right. Explain that after pressing the C chord, the right hand plays five, three, two and one string in turn. The general rule is that the thumb is responsible for four, five, six thick strings, the index finger is responsible for three strings, the middle finger is responsible for two strings, the ring finger is responsible for one string, and the little finger is basically not used. Below, let's introduce some special marks in the score: let's talk about rhythm first, music has rhythm, and it is necessary for us to learn to beat the time when playing the guitar. What is a beat? In fact, the beat is used to express the speed of music. We often say that the speed of a piece of music is 120, and the fast song is over 200. Hehe, the speed of playing is 80. Well, it's quite lyrical. The numbers here refer to the beat every minute. So how is the beat related to the notes (that is, the small vertical lines and small forks on the vertical lines that you need to play on the score)? Let's look at the duration of the notes first. These are several common notes, indicating how long each note needs to be played. The duration of a binary note is half that of a whole note, a quarter is half that of a binary note, and so on. Therefore, how long (seconds) a whole note or half a note needs to be played depends on the speed and time signature. We know that the beginning of a piece of music will have a time stamp, such as 4/4, 3/4 and so on. This is not a fraction. The number below the semicolon is a note, indicating the corresponding time length of a beat. The common one is 4, which means that taking a quarter note as a beat, combined with the speed of music (how many beats per minute), we can determine how long each note should be played. Of course, we can't grasp the speed as accurately as a machine, and this inaccuracy will not affect our playing effect too much, but we must ensure the relative duration ratio between notes at different times, otherwise the pop-up things will have obvious problems of inaccurate beat. So we must learn to grasp the time. Take quarter notes as an example (in fact, most songs are like this). For a whole note, when playing four beats, you should lift your feet first, then lift your feet again, and the whole note should fall and rise. Pay attention to playing this note at the moment when our feet land for the first time. These four ups and downs should be even, neither fast nor slow. Other notes and so on, remember: the rise and fall of the foot is always a beat, and the notes of other time values must be in tune with the rise and fall of the foot to play well. Try it: finally, let's introduce the rest. The notation symbol is 0, which means that the music stops here and the time is up to continue. Text tutorial:
