Once, while walking around the expanses of the Web, I accidentally stumbled upon a forum where the main topic was creating music on a computer, and this was done exclusively at home. And one of the words, in particular, used in those conversations, was the word MIDI keyboard.
For the first time, I came across a MIDI keyboard about ten years ago in the department of electric musical instruments of a music store. “On a shelf among synthesizers of all kinds, capabilities and cost, a wide and flat box with a row of piano keys and a big Roland name on the case lonely lurked. It seemed strange to me that I did not find any buttons other than the actual keys mentioned above.
The seller explained to me that this unit is called a MIDI keyboard, and it is intended solely for connecting to a computer. Continue reading
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
What to learn to play?
The training problem is one of the most important, but, unfortunately, the least covered, which often leads to disastrous results in terms of creative growth: without laying the proper basis at the very beginning of the path, it will subsequently be difficult to get on the right track. The first thing you need to decide is how seriously do you plan to master musical science. If the matter is limited to the performance of simple melodies, then, in fact, any device is suitable – regardless of the type of mechanics and the number of octaves. But if your intentions are more thorough, then this is completely different. In such a situation, you need an instrument with an 88-key (7 octaves) “heavy” hammer mechanics, which, by tactile sensations, is as close as possible to a real piano. The question of choosing a digital piano also requires a responsible approach, especially considering that a model with a high-quality keyboard and realistic sound is, alas, not cheap. Yes, but why not just buy an ordinary piano? – you will take an interest. Ideally, this should be done, only because it takes up a lot of space, needs periodic preventive maintenance and does not allow to output sound through headphones. Not to mention the single “built-in timbre.” Continue reading
Nature has given us legs and arms,
to save and defend ourselves – and we invented sport.
Nature gave us a sense of height
to sort the sounds of the world around us – and we invented music. ”
The task of the sound engineer — together with the composer and performer — is to create a sound image and transmit it to the listener using sound recording, sound reinforcement, broadcasting, soundtracks for film and television, etc. Continue reading
Performing as a special kind of artistic activity does not exist in all arts. In painting
for example, it is inseparable from creativity: to create a picture is what it means to “fulfill” it. Once in music, the creation and performance of a work did not separate from each other: in ancient times, a musician sang or played what he composed, improvised.
But the creation of a painter or sculptor is embodied in material that has been preserved for centuries, and the material of music (sound) lives while it sounds. Unsound, a piece of music ceases to really exist, disappears. To hear it again, it needs to be revived each time again, to make it sound again. The ability to do this is what is called the performing art. It’s clear now why performance (as special Continue reading
