Staves as Pitches and Durations in Time

From bib. source

Our system of musical notation is similar to a graph in which time is indicated on the axis and pitch is shown on the axis.

A staff [sic] is used in music to indicate the precise pitch desired. A staff consists of five lines and four spaces, but it may be extended indefinitely through the use of ledger lines.

The spaces are of course each treated as a unit called a “stave space” and are equal in size, while each line in a standard stave is known as a “stave line” (Kostka, Payne, and Almén 2018, 2):

Staves

From “Ground Rules¨ in Behind Bars

The size of every notational symbol is measured in proportion to the stave size. A stave-space is the distance between two stave-lines and is used as a measurement for notational symbols and spacing.

Staves can have any number of lines, but the most common conventional ones are the five-line and single-line staves. For the stave, lines run horizontally, and have equal vertical spacing among them.

Single-line staves are used (Gould 2011, 5):

  • To notate instruments of indefinite pitch
  • To notate sounds of indefinite pitch (e.g., percussive sounds) produced on pitched instruments
  • To notate vocal sounds of non-specific pitch
  • To notate a cue line of rhythm
  • As an option to show approximate pitch

Staves and the musical alphabet

Stave-spaces and stave-lines together vertically represent some segment of the looping sequence of the musical alphabet.

Horizontal lines that extend beyond the standard five-line stave are of course called ledger lines. The clef on a stave (Ibid):

From bib. source

[…] must appear at the beginning of the staff in order to indicate which pitches are to be associated with which lines and spaces.

There are a variety of clefs that determine different pitches for different lines.

A grand staff is:

From bib. source

[…] a combination of two staves joined by a brace, with the top and bottom staves using treble and bass clefs using treble and bass clefs, respectively.

A treble clef is the following:

Treble Clef

This clef looks like a ladle, whose top end curves like a snake back across the ladle handle, and then winds downward and back up crossing the ladle handle twice.

This winding portion is placed “around the G line¨ (Gould 2011, 6):

Which is to say, that the winding portion of the treble clef determines the note value of the horizontal stave-line it is on to be G natural (refer to musical accidentals). This is why it is also called the G clef (Ibid).
