Isochoriska

Isochoriska is a term that can refer to a few different concepts, primarily in the context of thermodynamics and sometimes in music. In thermodynamics, an isochoric process, also known as an isometric or isovolumetric process, is a thermodynamic process that occurs at constant volume. This means that during an isochoric process, the system's volume does not change. According to the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system, if the volume is constant, no work is done by or on the system. Therefore, any heat added to the system directly increases its internal energy and temperature. Conversely, if heat is removed, the internal energy and temperature decrease. An example of an isochoric process is heating a gas in a sealed, rigid container. The container's fixed volume ensures that the volume remains constant throughout the process, while heating increases the kinetic energy of the gas molecules, thus raising the temperature and internal energy.

In music, isochoric refers to a rhythmic or metrical organization where durations are not varied. This means that a series of notes or sounds would all have the same length, creating a very regular and often repetitive pulse. This approach is distinct from many other musical traditions that employ a wide range of durations to create melodic and rhythmic complexity.
