On top of all, remember that the sounds are the result of a series of vibrations that stimulate the ear and are transmitted in the form of waves through the air. The fact that musical instruments, and even the human voice, possessing the ability to produce different sounds is because not all of them are equal because the waves are not generated.

What makes it possible to distinguish the sounds? The sensitivity of the ear to identify them by their intensity, tone and timbre. The intensity can distinguish the sounds of the weak strong, thanks to the amount of energy released to spread the sound waves. The tone is a quality that distinguishes the bass and treble from the speed or frequency of sound vibrations are transmitted (if the vibrations are fast, the sounds are acute, if the sounds are slow severe). Moreover, the tone can be distinguished from the sounds of any musical instrument, because of this it is possible to differentiate the sound of a note in C, played on a piano, sound the same note played on a guitar.

The synthesizer is a creative machine, which can mimic any sound of nature (such as wind, waves of the sea or the song of a bird) or to simulate other sounds like a helicopter or a car. The synthesizer has the ability to imitate all the electronic and acoustic instruments, you can run several notes (with different tones) at the same time, as if he were playing an entire orchestra. Clearly, this ability to create sound and concentration was not well accepted among the players who were replaced by such an instrument in the recording studio. However, it appears that the potential of the synthesizer sounds with music provides a creative approach to the development of new sounds.

These characteristics and interpretive t'mbricas synthesizer and other equipment, such as the sequencer or sampler, put to music in a situation never before experienced. The variety of possibilities available electronic synthesizer allows the effects of a versatility and a range of records inaccessible to conventional instruments.

Invariably, these developments within the music has created new forms, new resources, where the composer has a lot of electronic music and computer components to develop their musical creativity. This allows musicians today have a full orchestra, at home, with a lowest operating cost.

Synthesizers use different systems to process the sound: subtractive, digital computer direct manipulation of magnetic tape or frequency modulation.

Previously it was thought to communicate only musical instruments, can now establish any communication with a printer, a modem or scanner. In fact, the computer MIDI music system allows the exchange of information between compatible electronic musical instruments (keyboards, sound cards or modules, samplers, etc.) and a computer.

The computer is also a writing instrument and interpretation of scores. When it comes to generating compositions, computer programs with musical notation in which you can write with your mouse, or playing a MIDI instrument, you can cut and paste any of the chances and score easily handle complex patterns for multiple interpreters are variable.
