At present, there are many metronomes on the market, but they are mainly divided into electronic metronome and mechanical metronome.
electronic metronome is small in size, light in weight and adjustable in volume. In addition, the electronic metronome is usually equipped with the sound of the standard sound la, which can be used as a tuner for violin or other musical instruments.
the mechanical metronome is slightly larger, so it is not very convenient to carry, and it is more suitable for home use. Mechanical metronome does not need batteries or charging, and it runs on mechanical clockwork, so it is durable. The following concrete analysis of mechanical metronome or electronic metronome is good:
1. Price: Mechanical metronome is more expensive than electronic metronome.
2. Beat conversion: the pendulum hammer of mechanical metronome hits once, and beat conversion is not allowed; However, the small electronic metronome has beat training content, including more complicated beat content such as dotted points and triplets.
3. Speed scale: The speed mark of the mechanical metronome is the scale that comes with the metronome, which is usually determined according to the up and down position of the hammer, which is slow up and fast down, but the numerical difference between each adjacent scale in the slow speed zone is very small, while in the fast speed zone, the situation is just the opposite. For example, in the fast zone 126-132, there are two adjacent scales, so it is very difficult for the user to adjust a certain speed in the middle. The speed mark of electronic metronome is completely digital and accurate. You can choose any kind of speed. In the same situation, you can speed up a little bit like 126, 127 and 12, knowing very well.
4. Carrying: In order to put the mechanical metronome on the top cover of the piano smoothly, its base is designed as a large triangle, so that people have to stand up to reach it every time they adjust the speed; Electronic metronomes are very small, which can be placed on the piano music stand at will, and some are simply designed as clips, which can be clipped on the score.
5. Power: The mechanical metronome is powered by hand, so it is troublesome to wind the spring after playing for a while. The electronic metronome needs no clockwork and is driven by battery.
6. Durability: The mechanical metronome is inconvenient to carry because of its large size. If you accidentally drop it, the beat you hear will be as inaccurate as a lame leg. The electronic metronome has a strong ability to resist falling, so as long as it can work after falling, the beat must be accurate.
7. Appearance: Mechanical metronome is classic in shape and stronger than electronic metronome.
Of course, the final choice of metronome mainly depends on the function of children's age to electronic products-if children are young and do not have the ability to use electronic products, then mechanical metronome can be considered. This metronome is simple to operate and only needs to move the pendulum on the metronome up and down according to the required speed. If the children are older, it is recommended to use the electronic metronome, which is small in size, cheap and easy to carry. In addition to different speeds, there are various types of rhythms, such as the rhythm types common in music, such as the attached point, the first eight after sixteen, the first sixteen after eight, and the triplet, which are incomparable to the traditional metronome. Therefore, electronic metronome is a better choice as long as children have the ability to operate electronic products simply.
2. How to choose the metronome
1. Mechanical metronome
(1) Check whether the pendulum needle of the metronome swings evenly from left to right with the slowest and fastest speed respectively;
(2) Listen to whether the metronome bell and the needle setting sound are loud, and the crisp and loud ones are high-quality products;
(3) Put the metronome on a horizontal plane to see if the three feet can support the weight of the metronome smoothly;
(4) When changing the rhythm again, we should pay attention to whether the bell of the first beat is accurate;
(5) See whether the scale of the metronome is accurate and clear;
(6) Look at the overall appearance of the metronome for scratches or defects.
2. Electronic metronome
(1) Check the outside of metronome for defects or bumps;
(2) Listen to whether the metronome sound is bright and noisy;
(3) Check that the contact of electronic switch button of metronome is flexible enough;
(4) Check whether all rhythms and tempo of metronome are accurate;
(5) check whether the metronome display is accurate.
