Harmonica cleaning steps based on harmonica
Step tool for cleaning harmonica
1, a set of screwdrivers, different brands of harmonicas need different types of screwdrivers, especially Horner MS series harmonicas, and it is best to use imported screwdrivers.
2, soft toothbrush.
3. Toothpaste is still a food-grade detergent. Different brands of toothpaste have different particle sizes. I like high ones.
4. Semi-dry and semi-wet towels and eye cloth.
step
1. Remove harmonica with a screwdriver.
2. Soak the toothbrush in warm water for 10 minute to make it softer.
3. Apply toothpaste evenly to the cover, seat and lattice of the harmonica (for wooden lattice, it is not necessary to apply toothpaste, just clean all parts with a dry toothbrush, but for acrylic lattice, toothpaste cannot be used, because abrasive particles in toothpaste will scratch the surface of acrylic lattice, so food-grade detergent should be used).
4. Then gently clean all the parts with a toothbrush. When cleaning, be careful not to let the toothbrush hair get stuck in the gap between the reed/seat plate. Attention should be paid when cleaning the metal lattice: some fonts are not printed firmly and are easily washed off during cleaning.
5. After completion, rinse with clear water. Be sure to scrub the water with a semi-dry and semi-wet towel, and don't damage the reed when wiping. I usually take the pat and wipe method. Put all the parts back. Finally, wipe the appearance with an eye cloth until it is very bright.
Harmonica 1 cleaning precautions. Wash with warm water below 40 degrees. Do not wash or scrub with boiling water or alcohol, decontamination oil and other chemical reagents, which may easily cause deformation or corrosion. For the wooden piano lattice that has not been waterproof, it should be disassembled and lightly brushed with a soft brush for decontamination.
2. It is suggested that friends with certain experience should be deeply cleaned, otherwise the reed will be easily broken and out of tune.
3. 1 > first disassemble the cover with a screwdriver, and remember the front and back of the upper and lower cover, so that it won't be put backwards when you put it back. Ten holes and chromatic scales are marked with numbers on the upper cover.
2> Then use a screwdriver to disassemble the seat plate embedded with the reed, and remember the positions of the upper and lower spring plates, so as not to put them backwards when putting them back. Remember that bass is on the left, reed is long, treble is on the right and reed is short. Sound-blowing reeds are in the upper row, with their openings facing the end of the piano, and sound-absorbing reeds are in the lower row, with their openings facing the mouthpiece.
3> Brush the grid lightly with a soft toothbrush (you can dip some toothpaste). When you brush the grid, brush it from the inside out. Don't suddenly put your toothbrush in Zeng's room, lest the reed suffer. Note: cold water must be used here. Only resin or metal harmonicas can be cleaned in this way. For the wooden lattice without waterproof treatment, the cleaning method is the same as the above except that the wooden lattice harmonica swells when it meets water, so you can only brush the wooden lattice gently with a soft toothbrush, but you can't use water.
3. There is also a simple dust removal method, which is to use a dust washer, but it needs to be properly controlled, otherwise the reed will be easily sucked off. Don't disassemble the harmonica like this.
Harmonica classification According to the purpose, harmonica can be roughly divided into two categories: solo harmonica and ensemble harmonica. The former mainly includes polyphonic harmonica (including stress and echo harmonica), semitone harmonica and blues harmonica. The latter includes bass harmonica, chord harmonica, brass harmonica and so on. [2]
According to the pronunciation mode, it can be divided into single-spring pronunciation and multi-spring pronunciation. The chromatic and blues harmonicas belong to single-reed pronunciation, as do children's toy harmonicas, necklaces and key-chain harmonicas. Polyphony, chord and bass harmonica belong to the latter.
Polyphonic harmonica
This is the most popular harmonica in China and even in Asia. Generally speaking, polyphonic harmonica has 16 to 28 holes, of which 24 holes are the most common variety in China. Japanese polyphonic piano also has 2 1 hole. The holes of the polyphonic piano are divided into two rows. Generally, when playing, the upper and lower reeds of the same hole sound at the same time. Because the vibration frequencies of the two reeds are slightly different, and vibration will produce a physical name at the same time? Shoot? This phenomenon is characterized by periodic changes in sound intensity, which is called. Tik Tok? . Is this also a polyphonic harmonica called abroad? Vibrato? Reason. Stress harmonica and echo harmonica can be considered as variants of polyphonic harmonica, both of which belong to polyphonic category. The former has an octave relationship between the upper and lower reeds, and the timbre is full and round; The latter has a cylindrical piano cover (piano shell) and has a unique * * * effect. The polyphonic harmonica has no less than 12 keys, the most common key is C, and there are also many A keys. The piano with C key has a high range, which sometimes seems harsh. It is generally believed that the range of piano is closest to human voice. In addition, a harmonica has two tones at the same time and a chromatic difference, so it can play chromatic scales and realize tuning.
chromatic harmonica
Chromatic harmonica is a more serious instrument than polyphonic harmonica. A complete chromatic scale, with a maximum range of more than four octaves, makes chromatic harmonica, who was born not long ago, occupy a place in regular musical instruments. Although not a full member of the traditional symphony orchestra, with the efforts of many harmonica masters, chromatic harmonica has gained a certain position in the field of chamber music, and there are also orchestras with chords and bass harmonicas at home and abroad. The common chromatic harmonica is that there are four sounds in a hole, and the sound absorption becomes a two-dimensional relationship. When the tone change key is pressed, each tone is raised by a semitone. As for the number of holes, there are 8, 10, 12, 14, 16 and so on. The range is two to four octaves, mostly in C. This kind of harmonica is suitable for playing more complicated music because it can play all semitones in the range. Chromatic harmonica's learning threshold is higher than polyphonic piano. On the one hand, it is difficult in music theory, on the other hand, it is also difficult to play: playing chromatic scales requires much higher breath control than polyphonic pianos, and at the same time requires strict coordination among breath, piano keys and keys. In addition, due to the production process, cost and other reasons, there are also manufacturers producing chromatic harmonica with one hole and two tones. Common ones are domestic 24-hole 48-tone piano, Japanese 17-hole piano and 22-hole piano. There is also a unique chromatic harmonica, which is similar to a polyphonic piano. It has two rows of holes, and the upper row is half a tone higher than the lower row. It is generally considered that the design of one hole and four tones is more formal. There is no precedent for more famous performers to choose the latter two kinds of pianos.

This is a very popular harmonica in Europe and America. Because the most common type has ten holes, the blues harmonica is also called the ten-hole harmonica. This kind of harmonica has two tones in one hole, and Ritcher tuning method is often used. There are two fifth degrees in the bass, not four degrees and six degrees. This design was originally produced by taking into account the needs of national music and playing some chords at the same time. However, the emergence of bending technology enables the original missing sound to be played, and at the same time adds unique charm to the blues harmonica. It can even be said that this is why the blues harmonica has become a blues harmonica. This is probably something that designers never thought of at first. This kind of harmonica is characterized by its small size and unique timbre. Humanization? Musical instrument. In blues music, this kind of harmonica is comparable to guitar. Besides, the blues harmonica is also suitable for playing some songs with national flavor. This harmonica is more difficult to learn than polyphony. One of the important reasons is that the flexible use of bending techniques requires long-term practice, and the unique music theory of blues harmonica also needs some energy to learn.
With the popularity of blues in Europe and America, after the bending technique, there are two techniques: overstretching and overblowing, which can obtain the rising and falling semitones that can not be obtained by bending on the blues harmonica. After that, the player can play 12 modes in any mode of the blues harmonica through the combination of bending and over-bending techniques.
