Introduction
In this article, we will be experimenting with showing the change in the tone quality of the violin’s note after the change in the position of the violin soundpost.
Basis Building Concept
When we change the position of the violin soundpost, our ear can not pick up the change, but an audio analysis program will pick up the change in sound.
Requirements
1. Violin with proper notes, violin tunes, and sound post.
2. Audio analyzer program installed in a computer.
Theory
1. The soundpost position controls the tension and balance of notes.
2. On moving the soundpost to the right, everything changes except for the E string, which is placed just above the soundpost.
3. On moving it to the left, only the E string was changed.
4. On moving the soundpost back and forward, every string changes except for the A string.
Procedure
Step 1: Violin, violin tune, and the length of note are the constants, while the position of the soundpost is the variable.
Step 2: Tuned the notes to the suitable hertz.
Step 3: Now, play every note into the program at various times.
Step 4: Note down this data.
Observation
When we change the position of the violin soundpost, we cannot detect the change, but the audio analyzer can detect it.
Result
1. The change in the quality of tone can be detected by an audio analyzer program.
2. Those who were present at the time of the experiment could not hear the tone, but the computer picked up the tone.
3. This means that you have to use an audio program to detect the tone quality of violin notes.
Conclusion
In this way, we have seen that there is a small change in the tone quality of the violin’s note after the change in the position of the soundpost.
Precautions
1. Make sure that the program is working properly.
2. Record the observations carefully.
Viva Questions with Answers
Q.1 What was the aim of our experiment?
ANS Show the change in the tone quality of the violin’s note after the change in the position of the soundpost.
Q.2 Why could a human not detect the change in the tone quality of a violin’s note?
ANS. A human ear could not detect it because the change was very small, which can be detected by a normal human ear/
Q.3 How could you detect the change in the quality of tone?
ANS. We can detect this change with an audio analyzer.
Q.4 What were the constants in our experiment?
ANS. Violin, violin tune, and the length of note were the constants.
Q.5 What was the variable in our experiment?
ANS. Soundpost
Q.6 What changes on moving the soundpost to the left?
ANS. On moving the soundpost to the left, only the E string changes.
Q.7 What changes on moving the soundpost to the right?
ANS. On moving the soundpost to the right, everything changes except for the E string, which is placed just above the soundpost.
Q.8 What changes on moving soundpost to backward and forward?
ANS. On moving the soundpost backward and forward, every string changes except for the A string.
