What is Staff (music)?
A '''staff''' (or '''stave''') is the name given to the five [[horizontal]] lines on which we can write music. [[Note (music)|Musical notes]] can be placed either on a line (i.e. with a line going through the middle of the note head) or in a space. There are four inside spaces as well as the two outer spaces at the top or bottom. The [[high|higher]] the [[Pitch (music)|pitch]] of the note the higher it will be on the staff. Taking the white notes of a keyboard: each note (A, B, C, D etc.) is placed higher on the stave (line, space, line, space etc.). A [[clef (music)|clef]] is needed to show which notes they are. There are different clefs to suit high, medium or low instruments. :[[Image:Beethoven symphony 5 opening.svg|350px]] This musical example shows the opening of ''Symphony no 5'' by [[Beethoven]]. The first three notes are on the second line (counting from the bottom). They are Gs, because there is a treble clef at the beginning of the staff. The fourth note is a little lower: on the bottom line, the E line (because of the flats in the [[key signature]] it is an E flat). The next note is between the other two in pitch (an F). After the three Fs comes a D in the outside bottom space. Sometimes composers have used staves with fewer or more than 5 lines, but the five-line staff started to become the usual one in Western music in the [[13th century]]. When notes are a little too high or low to put on the stave, [[wikt:extension|extension]] lines are used. These are called [[ledger line|ledger lines]]. If two or more staves are being played at the same time the staves are joined on the left by a bracket which is called a '''brace'''. [[Piano]] music, for example, is written on two staves: one for the [[Position|right]] [[hand]] and one for the [[left]]. Instruments that only play a [[rhythm]] (such as the [[cymbals]]), do not need a stave. The notes can be written just on one line. The beats are crosses. It's modern notation started from the Catholic Church.<ref>{{Cite web|url=https://makingmus
