On the question of geographic point of origin, 20th-century linguists agreed that the Yutonahua language family originated in the Southwestern United States. [5] [6] The Uto-Aztecan family has been accepted by linguists as a linguistic family since the beginning of the same century, and six subgroups are generally accepted as valid: Numic, Takic, Pimic, Taracahita, Corachol, and Aztecan.
In music, inharmonicity is the degree to which the frequencies of overtones (also known as partials or partial tones) depart from whole multiples of the fundamental frequency (harmonic series). Acoustically, a note perceived to have a single distinct pitch in fact contains a variety of additional overtones.
The degree of roundness points to the range and mode of transport of clastic material, and can also serve as a search criterion in mineral exploration, especially for placer deposits. Alluvial debris in major rivers tend to exhibit a high degree of roundness. Alluvium from small rivers is less rounded.
Research has shown that the larynx, the pharynx and the oral cavity are the main resonators of vocal sound, with the nasal cavity only coming into play in nasal consonants, or nasal vowels, such as those found in French. This main resonating space, from above the vocal folds to the lips is known as the vocal tract. Many voice users experience ...
The ambitus of this mode extended one tone lower, to D. The sixth degree, C, which is the tenor of the corresponding third psalm tone, was regarded by most theorists as the most important note after the final, though the fifteenth-century theorist Johannes Tinctoris implied that the fourth degree, A, could be so regarded instead.

They are sometimes collectively known as the shell. The term rime covers the nucleus plus coda. In the one-syllable English word cat, the nucleus is a (the sound that can be shouted or sung on its own), the onset c, the coda t, and the rime at. This syllable can be abstracted as a consonant-vowel-consonant syllable, abbreviated CVC.
Cratons of South America and Africa during the Triassic Period when the two continents were joined as part of the Pangea supercontinent. A craton (/ ˈ k r eɪ t ɒ n / KRAYT-on, / ˈ k r æ t ɒ n / KRAT-on, or / ˈ k r eɪ t ən / KRAY-tən; [1] [2] [3] from Ancient Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two ...
The colour scale is logarithmic and saturated at one hundredth the maximum power in the signal, to make the modes more visible. The low-frequency region is dominated by the signal of granulation. As the angular degree increases, the individual mode frequencies converge onto clear ridges, each corresponding to a sequence of low-order modes.
