As a traditional Chinese musical instrument, the erhu is deeply loved by people for its unique timbre and expressiveness. However, in order to play a beautiful erhu music, you first need to ensure the intonation of the instrument. As an important tool for tuning musical instruments, tuners are indispensable for erhu players.
In the performance of the erhu, intonation is very important. An inaccurate erhu not only fails to accurately express the emotion of the music, but also makes the listener feel unhappy. Therefore, before playing the erhu, it is necessary to carry out strict tuning work. The tuner is an important tool to achieve this.
The principle of use of the tuner is based on the measurement of the audio frequency. By measuring the vibration frequency of the erhu strings, the tuner can determine the accuracy of the pitch. When the frequency of the string vibrates at the same frequency as the standard frequency set by the tuner, the tuner will display a "green light" to indicate that the string is in tune accurately. If the string vibrates at a frequency lower than the standard frequency, the tuner will display a "red light" indicating that the string is on the low pitch and needs to be adjusted.
When tuning the erhu, you need to determine the benchmark pitch first. Usually, the benchmark pitch of the erhu is one pitch between d-a. Then, by adjusting the tightness of the strings, the vibration frequency of the other strings is consistent with the reference pitch. During the tuning process, the tuner's "+" and "-" buttons can be used to fine-tune the tightness of the strings until all the strings are in tune as required.
In addition to the reference pitch, you also need to pay attention to the pitch of each position. During playing, the pitch of different positions is different. Therefore, when playing a piece of music, it is necessary to fine-tune the pitch of each position according to the requirements of the piece and the player's feel to ensure the perfect presentation of the piece.
In addition, in order to ensure the accuracy of tuning, the following points need to be noted:
1.Make sure the tuner is accurate. You can prepare a few more tuners and calibrate them regularly.
2.Before using the tuner, leave the erhu for a while to allow the strings to stabilize gradually. This avoids errors due to changes in the temperature of the strings.
3.During the performance, care should be taken to keep the hand shape stable. The stability of the hand is very important to ensure the accuracy of the intonation. If the hand shape is unstable, it will affect the vibration frequency of the strings, resulting in inaccurate intonation.
4.When adjusting the strings, avoid pulling the strings too hard. Excessive pulling can cause the string to deform, affecting the stability of its vibration frequency.
In short, the tuning of the erhu is very important. By using the tuner, you can complete the tuning work quickly and accurately, so as to ensure that you can play beautiful erhu music. For erhu players, mastering tuning skills is one of the essential skills.
