Summary
Singers reduce vibrato rate and extent when singing nonvibrato compared to habitual and classical styles. Further research is needed to understand the mechanisms behind vibrato changes in singing.
Area of Science:
- Vocal pedagogy
- Acoustic analysis of voice
- Singing voice science
Background:
- Vibrato is a key component of singing quality.
- Factors influencing vibrato characteristics are not fully understood.
Purpose of the Study:
- To investigate how vowel, production type, gender, voice type, and vocal training affect vibrato rate and extent.
- To compare vibrato in habitual, best classical, and nonvibrato singing productions.
Main Methods:
- Cross-sectional study involving 78 male and female vocal majors.
- Data collected by four collegiate voice teachers using a standardized protocol.
- Analysis of vibrato rate and extent for five vowels across three production conditions.
Main Results:
- Vibrato rate and extent were significantly reduced in nonvibrato singing compared to habitual and classical singing.
- Findings align with existing literature regarding high vs. low and female vs. male vibrato characteristics.
Conclusions:
- The study highlights differences in vibrato based on singing production.
- Mechanisms underlying vibrato rate and extent reduction require further investigation.

The study of music provides many examples of the superposition of waves and the constructive and destructive interference that occurs. Very few examples of music being performed consist of a single source playing a single frequency for an extended period of time. A single frequency of sound for an extended period might be monotonous to the point of irritation, similar to the unwanted drone of an aircraft engine or a loud fan. Music is pleasant and exciting due to mixing the changing frequencies...

01:04Problem-Solving: Tuning of a Guitar String
1.2K
In the case of stringed instruments like the guitar, the elastic property that determines the speed of the sound produced is its linear mass density or the mass per unit length. This is simply called the linear density. If the string's linear density is constant along the string, then the linear density is simply the total mass divided by the total length.
The string's wave speed can be regulated by varying the linear density. Tension is the other property that determines the speed of...

01:05Intensity and Pressure of Sound Waves
1.9K
The intensity of sound waves can be related to displacement and pressure amplitudes by using their wave expressions and the definition of intensity. The critical step to achieve this is to write the power delivered by the particles on the wave as the product of force and velocity and simplify the force per unit area as the pressure. The velocity of the medium's particles can be derived from the displacement.

01:01Perception of Sound Waves
6.0K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
2.2K
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

01:14Sound Waves: Resonance
3.7K
Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...
