What is staff?

What Does staff Mean

It is known as a pentagram (or pentagram , according to what is indicated in the dictionary of the Royal Spanish Academy ) to a form of musical notation that is based on a structure composed of five lines located in parallel and at the same distance apart.

The staves are used to write music , that is, to record the notes and other musical signs necessary to interpret a melody on a written medium. All lines on the staff, as well as its four spaces, are numbered in the bottom-up direction.
At the beginning of the staff the key is placed, which is the symbol that allows each musical note to be related to the location or space it occupies on the staff. This clef connects a note to a specific location on the staff, making the other notes correspond to certain adjacent locations and lines.

The treble clef is the most popular outside the field of music, although it is very rare to find a score that does not include a staff in the bass clef, unless it refers to a "part" of an orchestrated piece, that is, the line to be played by a particular instrument. In any case, an experienced musician fluently reads the different keys, in their possible positions. It is worth mentioning that it is possible to alter the initial key throughout a composition as many times as desired, either accidentally (temporarily) or permanently (until the next change).
Basically, a bare staff is useless, as it is impossible to associate a line or a space with a note . After assigning a password, everything changes. However, this is not enough, since if no further clarification is made, it will only be possible to write melodies in C major or A minor (which are relative keys).
To understand it graphically, it is very useful to think of a piano; A staff with an F clef on the fourth line gives us the possibility to use the notes do, re, mi, fa, sol, la and si, unless an accident is indicated throughout the piece. Despite the redundancy, these are the notes belonging to major and its relative minor, which excluded many other colors .
This is where the key signature comes in , which plays a fundamental role when composing a musical work. It consists of one or more flats or sharps (cannot be mixed) that indicate permanent accidentals to the seven notes listed in the previous paragraph. To build a key signature, it is mandatory to follow one order with the flats, and the opposite for the sharps. In the first case, the sequence is si mi la re sol do fa , and to understand its function, we will take as an example the simplest key signature of this group, which has only B flat: with this configuration, the two keys that can to be reproduced are F major and its relative minor, Re.

After the key signature, the figures representing the musical notes appear. Each figure indicates the duration of the sound and, according to its location on a line or space, the musical pitch. In case a tone is needed that is not covered by the staff (higher than the one corresponding to the space above the fifth line, or lower than that of the space below the first line), additional lines and spaces can be drawn .
In addition, there are several signs that make musical notation on a system very rich and complex; some of them allow to indicate intensity, way of attacking the notes (chopped, sustained, tied), dynamics (make the intensity increase or decrease in a certain portion of the melody).
