You are watching: The relative highness or lowness of a sound is called


Pitch is identified as the family member highness or lowness of sound. This is a general definition: in music us speak the pitch as a certain tone that is particularly placed and also notated. Pitch-class, a reasonably recent term, defines a generalized or generic partnership of pitches the sound basically identical however are be separate by a sense of highness or lowness. Pitch-class additionally refers to tones that share the very same “pitch-space,” that is, castle sound identical, however are “spelled” differently.


The Staff

Since early on notation to be not details as to specific placement the pitch, a device of parallel horizontal present came right into use in stimulate to display exact placement.Interestingly, earlier systems the notation use parallel lines had been in use. Many used only the lines us to find pitch, no the spaces between. This employee originated as a mechanism of eleven parallel present that incorporated the theoretical expectations of easily accessible pitches, which to be the variety of the male voice from base to male Soprano.In St. Paul’s Epistle to the Corinthians he delivers an injunction come “Let her women store silence in the Church…” This ended up being the rationale for the exclusion of females from authorized in the early on church. In practice, this complete system was restricted to four or five parallel currently encompassing the range of a given chant melody or voice part.

Pitches were assigned particular names. The lowest pitch, referred to as gamma, extended to the highest pitch, ut: the convulsion of these two terms, gamut, has gone into the language to mean “a complete range or scope.”

The eleven-line system is visually cumbersome. In beforehand music details lines to be colored with different dyes, every line locating a details pitch. All various other pitches were organized in relation to these. In time, the eleven-line staff was separated right into two five-line staves. The continuing to be line in between the two staves was no drawn, yet was taken as gift “shared” by each staff.

Specific icons came into use, replacing the fancy lines. Clefs (French-“key”) offered the same function as fancy lines, locating precise pitches roughly which all other pitches were calculated. This clefs represented general voice ranges and also their name reflect this.

We brand pitch-classes by the usage of letter-names. Various other labels are questioned in ar 2.2 "Chromatic Alteration: Accidentals". The Treble Clef (or “G-clef”), nominally denote a high voice, locates the pitch “G” on the 2nd line up on the staff.

The base Clef (or “F-clef”) locates the key “F” on the 4th line increase on the staff. From this two solved points, all various other pitches to be calculated and also placed top top the five-line staff. Number 2.2 reflects the Treble and Bass Clefs and also pitch placement on lines and spaces.


Treble and Bass Clefs, The grand Staff

Figure 2.2 Treble Clef and also Staff; base Clef and also Staff

These two staves are linked into a system referred to as The grand Staff.In notation we call complete lines the music a system. This shows its origins from the Guidonian staff: 2 five-line staves, slightly separated, the staying invisible middle line shared by both. The cool Staff now yields the potential because that locating and notating all pitches, from lowest to highest.

Figure 2.3 The grand Staff

In number 2.3 pitches are listed just outside the borders of every clef top top the cool Staff. Because the two staves (Treble and also Bass) are separated native one an additional in the cool Staff, that is necessary to use symbols to expand each beyond its five-line boundaries.



Ledger Lines

Short horizontal dashes are used to prolong the variety of one of two people staff, above or below. This dashes, referred to as ledger lines, offer as truncated employee lines. They may occur over or listed below a notehead, or they might bisect a notehead.

Figure 2.4 Ledger Lines

The student need to exercise specific care when drawing ledger lines. A usual mistake the nascent music college student is put the ledger heat on the wrong side of the notehead. When illustration notes watch several other properties:

Stems prolong up or down from the notehead come the following pitch-class the the same name.This exercise for notating stem length has actually its early origins as a key designation, not as a durational value.Stems are drawn down from noteheads ~ above the middle line the the staff and above. Below the middle line, tribe are drawn up.In prolonged passages throughout the center line the the staff, stems might be the same direction. There is no rule for this: it is a matter of visual uniformity.For stems up: the stem is constantly on the best side of the notehead. Because that stems down: the stem is constantly on the left next of the notehead.Stem placement has not constantly been uniform. As soon as studying scores of earlier music, one will conveniently observe the stem placement in relationship to the notehead appeared to be a issue of choice, style, or convenience

Pitch placement on the Staff

Using this notational devices and practices, precise pitch placement have the right to be shown. Note that the pitch that is one ledger line over Bass Clef is identical to the pitch that is one ledger line below Treble Clef (both room “Middle C”). This shared, connective key is storage of the middle line indigenous the Guidonian staff and also serves to attach the two staves.
