Violinists often practice with mutes, the purpose of which is to reduce the volume so the sound does not disturb other people. There is however a great disadvantage; practice mutes not only lower the volume but change the timbre dramatically, making it unpleasant to the ear. Previous researches mostly focus on how to find the elusive “Stradivarius Sound.” On the other hand, via sound analysis, we empirically study different mutes, in order to identify the markers that allow the violin to retain its “Signature Sound.” The general problem lies in the complexity of violin sound propagation and its perception. Here, we show that all types of mutes necessarily diminish the frequency band of 1.5–2.5 kHz, which tips the balance of the sound toward a darker color. The results demonstrate that unless a proportional balance between the amplitude of the harmonics of each tone is maintained, the sound loses its Brilliance character. In addition, some mutes tend to add spurious resonance peaks at lower frequencies, wh... |
