Summary
A new vocal ornament, the single cycle ornamentation structure (SCOS), in Byzantine chant has a greater extent and different spectral characteristics, including noise-to-harmonics ratio and spectral slope, compared to vibrato.
Area of Science:
- Vocal acoustics and historical musicology.
Background:
- Byzantine chant (BC) features unique vocal ornaments.
- The single cycle ornamentation structure (SCOS) is a specific ornament in BC.
- Vibrato is a common vocal technique for comparison.
Purpose of the Study:
- To define and compare SCOS with vibrato.
- To analyze time-domain (rate, extent) and spectral (slope, formant levels, bandwidths, noise-to-harmonics ratio) characteristics.
- To investigate acoustic differences between SCOS and vibrato.
Main Methods:
- Comparative acoustic analysis of SCOS and vibrato from recordings of four chanters.
- Measurement and statistical analysis of time and spectral parameters.
- Comparison of parameter differences between ornaments and adjacent steady tones.
Main Results:
- SCOS exhibited approximately double the extent of vibrato.
- SCOS showed different rate characteristics compared to vibrato.
- Significant differences were found in noise-to-harmonics ratio (higher for SCOS), spectral slope (lower for SCOS), and speaker's formant level (lower for SCOS) between SCOS and vibrato.
Conclusions:
- The single cycle ornamentation structure (SCOS) is acoustically distinct from vibrato in Byzantine chant.
- Key differentiating features include extent, noise-to-harmonics ratio, spectral slope, and speaker's formant level.
- Further research may explore formant tuning effects in vocal ornaments.

01:04Problem-Solving: Tuning of a Guitar String
1.1K
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...

01:11The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

According to the theory of resonance, if two or more Lewis structures with the same arrangement of atoms can be written for a molecule, ion, or radical, the actual distribution of electrons is an average of that shown by the various Lewis structures.
Resonance Structures and Resonance Hybrids
The Lewis structure of a nitrite anion (NO2−) may actually be drawn in two different ways, distinguished by the locations of the N–O and N=O bonds.

01:14Sound Waves: Resonance
3.5K
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...

Elaborative rehearsal is a crucial cognitive strategy that strengthens information encoding in long-term memory by making meaningful connections between new data and pre-existing knowledge. This approach contrasts with maintenance rehearsal, which involves simple repetition without delving into the significance of the information. While maintenance rehearsal might temporarily keep information active in short-term memory, it is less effective for long-term retention.
