How to make your own musical instrument in the feeling?

Physical homemade musical instrument experience Physics in musical instruments Musical instruments are machines that make ** sound Therefore, any kind of musical instrument is actually an acoustic instrument Let's further analyze the structure of the musical instrument First of all, a musical instrument must have a sound source, that is, a vibration source The vibration source of a stringed instrument is a vibrating string The vibration source of a wind instrument can be a vibrating reed. Such as clarinet, can be the vibration of the lips, such as brass instruments, can also be the edge of the formation of the air flow vibration, such as the flute The source of the reed vibrating instrument is the vibration of the reed, the vibration source of the drum is a circular film, the source of the bell is the whole bell body, and the source of the electronic instrument can be a quartz oscillator or an oscillating circuit The source of the vibration is indispensable for any musical instrument. Musical instruments have sound emitters Some musical instruments vibrate from the sound body, such as drum skins, bells, harmonica or accordion reeds, etc. ** The instrument relies on the tube to determine the tone The air forms a standing wave in the tube, and the sound is transmitted through the nozzle Some reed wind instruments are made by the reed and the pipe together to determine the tone, and the sound is made at the nozzle Many musical instruments also include the resonance body For example, the string of the violin vibrates to produce a certain tone, but the sound is very small, almost inaudible, through the piano horse, the sound column transmits the vibration to the upper and lower soundboards of the piano case, It is only by making the strings resonate with the case that the sound of the violin we hear today can be produced.

The classification of musical instruments is based on the physical mechanism of their sound The properties of the materials used to make musical instruments, such as humidity, hardness, elastic modulus, density, the propagation speed of sound waves in the material, the damping properties of the material, the acoustic impedance, etc. That is the physical properties The treatment of materials, such as artificial aging, humidification, baking, upper protective layer, etc., are all physical methods, and physical measuring instruments are used Many methods for studying musical instruments such as spectrum analysis, waveform observation, laser holography, acoustic and electric simulation, etc. are physical methods The preservation and maintenance of musical instruments such as maintaining a certain temperature, humidity, etc., are all physical environments Physics in Musical Instruments Zhang Wuji Abstract: This paper mainly introduces the simple classification of various musical instruments and the specific vocal mechanism of various musical instruments, and also lists some simple principles of "piano" and "flute", so that abstract physical words such as "audio", "timbre", "loudness", "sound impedance" and "elastic modulus" have further come face to face with us.

Although the homemade instrument may not be as good as the one you bought, it is very rewarding to make the homemade instrument, and you will have a strong sense of self-confidence.

Allowing students to make their own percussion instruments can not only exercise their hands-on ability, production ability and creative ability, but also allow them to understand the composition and structure of the instrument in the process of making their own percussion instruments, and can better understand how the instrument is generated, as well as the principle and meaning of the instrument, experience the beat, rhythm, master the skills of using the instrument, and learn to play the self-made instrument, and experience the joy of success brought to them by the self-made instrument. The materials of homemade percussion instruments can be selected from daily necessities, such as paper, plastic bottles, tin foil cans or sand, etc., teachers can first provide methods of making self-made percussion instruments, and then try to innovate when students make finished products, so as to train students' sense of innovation, expand their thinking, and give children full freedom to play. In addition, it can also take the form of group cooperation, so that students have a more sense of teamwork and a sense of help, and can also allow students to exercise their expression skills in cooperation, express their self-control ideas to others, and can explain and play their own group works in front of the whole class, which is very beneficial to cultivate students' self-confidence and training expression ability.

2) Mobilize the classroom atmosphere.

Instrumental music performance is indispensable in classroom teaching, which is of great help to improve students' understanding of music theory, enhance students' ability to express and create, and stimulate students' interest in music. In traditional classroom teaching, the common form is that the teacher explains some theoretical knowledge, and then collectively learns to sing a song, most of which are boring and boring, or invite classmates to perform on stage, and those students who are relatively shy and not good at singing are not afraid to perform on stage. And through the way of self-made percussion instruments, every student can participate and have a deeper understanding.

Teachers can classify students' self-made musical instruments and complete a complete piece through the performance of different instruments, which fully improves students' enthusiasm and mobilizes the classroom atmosphere.

1. First of all, find a plastic cup and put some plastic beads in it, or beans and grains can also be used.

2. Next, fasten another plastic cup on top.

4. Then, use pigments to make some decoration for the plastic cups.

5. Finally, hold the finished small musical instrument in your hand and shake it, and the beads and beans will make a nice sound when they hit the wall of the plastic cup.

Here's how to make your own musical instruments:

1. Select a sand bell container. You can use aluminum coffee cans, glass jars with lids, or cardboard cylinders. You can also use wooden containers. Each container emits a different unique snuffy sound.

2. Choose something that shakes. Any small object that makes a funny sound when shaken is fine. You can collect a handful of some or all of the following items: beads, whether plastic, glass or wood, dried bean or rice coin seeds.

3. Put the shaking small items into the container Zhaoling.

4. Cover the container with a lid.

5. Wrap the container with masking tape. Masking tape can be slightly overlapped to ensure that the container is completely covered.

6. Decorate your sandbells. You can use paints or other decorative objects to add bright colors and patterns to the sandbell.

<>7. Shake the sand bell. Use the sand bells as a stand-alone percussion instrument or with other band instruments.

As a Latin percussion instrument, the sand bell is mostly used in Latin jazz**, especially bassanova**. Pop** also uses the sand bell as a rhythmic accompaniment instrument. Sand bells are also used in modern orchestral compositions, but not in many famous cases.

The sand bell is also one of the commonly used musical instruments in **** or physics, and patients only need to make the musical instrument sound through a small amount of hand movement, so as to train the patient's hand mobility and tactile senses.

Here's how to make your own simple little musical instrument:

1. First of all, you can use old pots, bowls, vases or buckets, choose a sturdy deep-bottomed container as the drum base, and avoid using containers made of glass or other fragile items.

2. Prepare the balloon for making the drum surface, since you may break the balloon in the process of making the drum, it is best to buy multiple balloons for backup, and choose a sturdy big balloon to ensure that it fits the selected drum base.

3. Next, reduce the opening end of the selected balloon, and the new opening must be smaller than the diameter of the drum base.

4. After cutting the balloon, fix the balloon to one end of the drum base with one hand, and stretch the balloon to the other side of the drum base with the other hand, so that the balloon covers the opening of the pot, vase or bucket that is used as the drum base. Pay attention to fixation so that the balloon does not suddenly bounce back when the balloon is stretched.

5. After the balloon is stretched, use load-bearing tape or cloth tape to fix the balloon around the drum base.

6. At this point, the balloon drum is completed, and you can use chopsticks as drumsticks to play.

Musical instruments, English: musical instruments, generally refer to instruments that can play timbre and rhythm in various ways. Generally, it is divided into national musical instruments and Western musical instruments.

It is an instrument that can produce musical sounds and can carry out ** artistic recreation. Human beings play musical instruments to express and communicate thoughts and feelings. There are different views on the definition of musical instruments.

The classification of musical instruments is an important topic in musical instrument science, which can be roughly divided into two types: one is the customary classification of ethnic groups, also known as traditional classification; The second is the modern classification method based on acoustic physical induction, also known as logical classification.

Here's how to make homemade small musical instruments:

For the production of the rubber band piano, slippery acres need to prepare materials, 1 paper box with a lid, 1 piece of hard paper, 4 identical rubber bands, 1 one-yuan coin, pin, small plastic sheet, scissors, ruler, pen, glue; The production process involves cutting a 4 cm wide strip of paper from the cardboard, which is twice the width of the paper box; If the length of the paper is not enough, you can cut two pieces of paper with the same width as the carton; Fold the paper into a long triangular shape with a side length of 1 cm, and glue the excess side to the other letter; Place a coin on the bottom of the carton with the bottom side facing up, and draw a circle along the coin. Use a pin to prick a dense small hole along the round hole to make the round part fall off; Glue two triangular pieces of paper to the two ends of the carton to make a string horse; Put the rubber band on.
