clé de octaviée

A clef (from French: clef 'key') is a musical symbol used to indicate which notes are represented by the lines and spaces on a musical staff. Placing a clef on a staff assigns a particular pitch to one of the five lines or four spaces, which defines the pitches on the remaining lines and spaces.

[English] This is a normal treble clef symbol with the number 8 printed above or below. The addition of the number 8 directs the musician to perform the music an octave higher than indicated (with the number 8 printed above) or an octave lower than indicated (with the number 8 printed below).

6. Octave clefs. Octave clefs are variations of the treble clef and the bass clef that indicate the notes are played in a different pitch. The number 8 above the clef means that the notes are played an octave higher than notated. The number 8 below the clef means that the notes are played an octave lower than notated.

[English] This is a normal bass clef symbol with the number 8 printed above or below. The addition of the number 8 directs the musician to perform the music an octave higher than indicated (with the number 8 printed above) or an octave lower than indicated (with the number 8 printed below).

The Notation of Notes, Clefs, and Ledger Lines chapter introduced four clefs: treble, bass, alto, and tenor. A clef indicates which pitches are assigned to the lines and spaces on a staff.

In music, letter notation is a system of representing a set of pitches, for example, the notes of a scale, by letters. For the complete Western diatonic scale, for example, these would be the letters A-G, possibly with a trailing symbol to indicate a half-step raise (sharp, ♯) or a half-step lowering (flat, ♭).

one octave higher Sorted by: 6. It's an ottava-line. Or shorter: an 8va line. It means you should play those notes one octave higher than notated.

The treble clef is a symbol used to signify higher-pitched notes in contemporary musical notation, placed at the beginning of a staff. This is in contrast to the bass clef, which refers to a lower-pitched range of notes.

one octave lower In correct notation, the 8 below the clef indicates that the sound is one octave lower than the notation. This is important for playing the tenor part at actually sung pitch. In two-staff notation for four-part harmony, tenor and bass are notated together in a single bass clef and the tenor is then written at pitch.

An octave is the distance from one note with a particular letter name to the next occurrence of that same letter names note on the keyboard.

The word "octave" comes from a Latin root meaning "eight". It seems an odd name for a frequency that is two times, not eight times, higher. The octave was named by musicians who were more interested in how octaves are divided into scales, than in how their frequencies are related.

Pitch in Western musical notation is designated by the letters A, B, C, D, E, F, and G, which repeat in a loop. Different clefs make reading different ranges easier. Each clef indicates how the lines and spaces of the staff correspond to pitch.
