What is an operetta?

As an independent genre, operetta arose relatively recently, in the middle of the XNUMXth century in France. And before that, an operetta (translated from Italian "operetta" means "small opera") was called a small comic opera.

The operetta has everything: song verses, dances, conversational dialogues. And the operatic forms in the operetta - the aria, the vocal ensemble, the choir and the ballet scenes - have a lighter character.

Compared with opera, there are also new musical forms in operetta: couplets - songs almost always performed at a fast pace and recitative, as well as cancan - a fast dance, which often becomes the culmination of a performance. Great attention in operettas is paid, of course, to the text, which should be witty, cheerful, playful and very bright. Operetta artists must certainly have a good singing voice, acting skills and excellent diction.

 Random interesting fact from the Great Encyclopedia:

Why is the bashful mimosa called that?

The bashful mimosa plant is known for the fact that its leaves fold when someone touches it, and after a while they straighten again. This mechanism is due to the fact that specific areas on the plant stem, when externally stimulated, release chemicals, including potassium ions. They act on the cells of the leaves, from which the outflow of water begins. Because of this, the internal pressure in the cells drops, and, as a result, the petiole and petals on the leaves curl up, and this effect can be transmitted along the chain to other leaves.

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

A touch from a distance 02.02.2023

Japanese researchers have unveiled a system that allows users to transfer physical sensations and tactile information between devices.

Japanese mobile network operator NTT Docomo, together with Keio University's Embodied Media Project and Nagoya Institute of Technology's Haptics Lab, have developed the Feel Tech platform, which "makes it possible to share experiences that are usually difficult to convey through images, sound, text or words."

The inventors plan to use the technology in a variety of use cases, including healthcare, sports, education, and e-commerce. In particular, they plan to focus on medicine and art.

In addition, they suggest using the platform to "experience the subtle feel of clothing fabric, among other rich experiences that are not possible with other advanced technologies such as 3D or augmented reality."

The system detects a person's sensory state and helps to share tactile sensations by detecting vibrations from a person's touch with a device similar to a piezoelectric sensor and other devices connected to the platform, which then reproduce these vibrations for other users.

The platform is expected to take full advantage of the ultra-low latency that will be offered in future 6G mobile networks to achieve the important synchronization of transmitted tactile and video data, the researchers said.
