Prelude. About Prelude

Prelude (from lat. Prae … – before and ludus – game) – a short piece of music that does not have a strict form. At the time of its inception, the prelude always preceded the longer, more complex and strictly formalized work (hence the name), but subsequently the composers began to write preludes as independent works. Ostinato is often found in preludes; in general, preludes are similar in style to improvisation.

Prelude is an old genre and, at the same time, unusually sensitive to the latest requirements of the time, allowing many author’s decisions and interpretations. His fate is unusual: having arisen in the 15th century, the word “prelude” itself has repeatedly changed its meaning. Initially, this was a small instrumental introduction to some composition, sometimes written in advance, but most often improvised directly during the performance. Not constrained by the strict framework of the rules, it prepared the mood of the future play and at the same time allowed the performer to demonstrate inventiveness and virtuosity.

Improvisation, as well as the dominance of one image and a single, purely figurative type of texture, Continue reading

On the perception of sound and music. Sound Perception and Compression

Simple compression methods

Traditional lossless compression methods (Huffman, LZW, etc.) are usually poorly applied to compressing audio information (for the same reasons as when compressing visual information).

Some lossy compression methods are listed below:
Compression of silence (pauses) – defines periods of “silence”, works similarly to run-length coding.
ADPCM – Adaptive Differential Pulse Code Modulation (the term adaptive delta-pulse-code modulation (ADPCM) is used in Russian literature. For example, the CCITT G.721 standard is from 16 to 32 Kbits / sec: Continue reading

Reasoning about art

“The poet owns the form, and the content belongs to the history and reality of his people” (Belinsky; compare Glinka: “The people compose music, we only arrange it”). Consequently, the artist’s task is to discover (and not invention) the content and invention for him the form corresponding to him (expressing the form in a broad, philosophical sense).
Chernyshevsky argued that art is a weak likeness of life and that, for example, paintings depicting the sea are needed only by those who have not seen the real sea. But it seems that the old woman, who served as the original for the Rembrandt picture, did not attract such attention as this picture, and that the living Continue reading
