In music, voice crossing is the intersection of melodic lines in a composition, leaving a lower voice on a higher pitch than a higher voice (and vice versa). Because this can cause registral confusion and reduce the independence of the voices, [ 1 ] it is sometimes avoided in composition and pedagogical exercises.
Voice exchange is also used in Schenkerian analysis to refer to a pitch class exchange involving two voices across registers, one of which is usually the bass. In this sense, it is a common secondary structural feature found in the music of a wide variety of composers. [12]
In social sciences, a cross-cutting cleavage exists when groups on one cleavage overlap among groups on another cleavage. "Cleavages" may include racial, political, religious divisions in society. "Cleavages" may include racial, political, religious divisions in society.
The zero-crossing rate (ZCR) is the rate at which a signal changes from positive to zero to negative or from negative to zero to positive. [1] Its value has been widely used in both speech recognition and music information retrieval , being a key feature to classify percussive sounds.
The overlapping generations (OLG) model is one of the dominating frameworks of analysis in the study of macroeconomic dynamics and economic growth.In contrast to the Ramsey–Cass–Koopmans neoclassical growth model in which individuals are infinitely-lived, in the OLG model individuals live a finite length of time, long enough to overlap with at least one period of another agent's life.
Modal voice is the vocal register used most frequently in speech and singing in most languages. It is also the term used in linguistics for the most common phonation of vowels . The term "modal" refers to the resonant mode of vocal folds ; that is, the optimal combination of airflow and glottal tension that yields maximum vibration.
Because of the overlap and synergy between long-distance telephone networks and backbone networks, the largest long-distance voice carriers such as AT&T Inc., Verizon, Sprint, and Lumen also own some of the largest Internet backbone networks. These backbone providers sell their services to Internet service providers.
The ecological effects of economic activity spur research upon changing market economy incentives. Additionally and more recently, ecological theory has been used to examine economic systems as similar systems of interacting species (e.g., firms). [59] Cultural studies examines social class, production, labor, race, gender and sex.
