A single-voice or monophonic synthesizer is a synthesizer that can play only one note at a time, that is, you will not play a chord on such a synthesizer. Rather, you take it, but only one of the notes of the chord will sound. As a rule, the notes will alternate, for example, you have several chords in different keys, from which a melody or some kind of pad is composed.
A polyphonic or polyphonic synthesizer is capable of playing several notes at the same time (no more than Continue reading
The tempo in music is the speed of metric counting units (the ratio of the number of events that happened to the time they took).
According to a long tradition, the tempo is designated in Italian and is set at the very beginning of the musical notation of the work. The main designations of tempo in ascending order:
grave, largo, adagio, tape (slow pace);
andante, moderato (moderate pace);
animato, allegro, vivo, presto (fast pace). Continue reading
Musical notation is an ordered set of musical notation symbols designed to convey some musical material in writing.
Musical notation – a system of graphic characters used to record music. Each of the well-known notation systems has its own set of musical notes, differing in form and names.
A note (Latin nota – sign) is a conventional graphic sign located on a stave (a bearer, as the five lines are sometimes called, on which notes are recorded) and indicating the pitch and relative duration of a sound.
Often the term “note” is used to mean sound. So, “sound up” and “note up” can be perceived as one and the same.
Now, it is impossible to imagine that there was a time when there was no musical recording in the world and music was transmitted only verbally. The urgent need to find a way to preserve musical tunes has led to the creation of musical notation.
Through the efforts of many generations, more and more advanced systems have been created for translating the Continue reading
In a sense, sound engineering is the science of distortion, with which there is a continuous struggle on all sections of the sound path. All distortions can be divided into linear and nonlinear. The former only affect the level and shape of the signal, changing them, while the latter add foreign products to the signal that were not in the original input signal.
Nonlinear distortion includes THD (Total Harmonic Distortion) – harmonic (and subharmonic) distortion, IMD (Intermodulation distortion) – intermodulation distortion (combination, difference and total frequency), the most noticeable by ear, dynamic (clipping, “step”, overmodulation) .
To linear – amplitude-frequency (distortion of the frequency response, that is, unevenness), phase-frequency (phase response), temporal, spatial (for example, related to directivity), transient (distortion of transients).
Frequency response – amplitude-frequency characteristic – graphical relationship between a constant Continue reading
The network (power) is noisy at a frequency of 50 Hz (and multiplied). To eliminate this, you need to remove the frequencies of 50 and 100 Hz using a parametric equalizer, the bandwidth of which is quite narrow. Then this will not significantly affect the overall sound, but will eliminate the network noise. The graphic equalizer (one third of an octave) is also applicable in this situation, but it is better not to use the other types of equalizers, since they have too wide (influence zone) and the adjustment can seriously change the sound of the 6ac guitar.
The lower frequencies of the bass guitar and bass drum lie in the region of 40 Hz or less. To give these sounds power (attack), adjust the frequency to 80 Hz. Many modern microphones designed for the bass drum have a small peak at this frequency, which allows you to achieve a good, thick sound. Continue reading
