The arc above the number, that is the meaning of Legato, that is, all the notes below the arc should be played together and cannot be disconnected.
The number of points in a number. This point is called the attachment point, which means that the duration of the previous note is increased by half. Dot notes are called dot notes. Such as: eight notes: 5. =5+5 (with a horizontal line below) = one and a half beats.
Some views on the score of electronic organ;
1, the notation of electronic organ should first look at the sound, and then translate it into C major.
2, the note number 1 is do, 2 is lui, 3 is mi, and so on.
3. Beat: Take the four-two-four-three-four-four-four-four-four beat as an example: if a single note has nothing to play and there is a line at the bottom of the two notes together, then the two notes are played once, and one is a half beat; If there are two lines at the bottom of four notes, then these four notes are played once and one is a quarter beat.
If there is a dot on the right side of a note, followed by a note, and there is a line under these two notes, then the note with a dot plays three quarters of a beat, and the note behind it plays one quarter of a beat; If there is a dot on the right side of a note and there is no line below it, play half a beat, and the notes behind it play half a beat.
4, arc refers to the sound line, that is, to maintain coherence; If the same tape is connected, play the first tone until the duration of these two tones is full.
5. Pitch: The notes on the upper point are high notes, two points are high, the lower point is low notes, and two points are low notes.
6. Each vertical line represents a bar.
Electronic organ/electronic organ
The electronic organ is a keyboard instrument, but it is actually an electronic synthesizer. In fact, the electronic organ is not a correct name at all. Because it looks like a piano, some people call it the electronic organ. Actually, the official name should be electronic synthesizer.
It uses large-scale integrated circuits, and most of them are allocated with sound memory memory (wave table). It is used to store the real sound waveforms of various musical instruments and output them when playing. There are two kinds of electronic organ in common use: arranger keyboard (with automatic accompaniment) and synthesizer (without automatic accompaniment).
Electronic organ in a broad sense includes electronic organ (digital organ, different from electro-acoustic organ), and most of them use staff notation, mostly high and low double-line notation. Sometimes we also use alto spectrum, simple spectrum and guitar spectrum. Generally used in rock music.
