Disposition of notes

Disposition of notes on the staff

In solfeggio , representation of heights uses four types of signs: the scope, the figures of note, keys and alterations.

Principles rating

Figures of note, whose form can also indicate the length, are placed either on the lines or between the lines of the staff. The height is indicated by the position of the head of the figure of note - the presence of a pole is not taken into account.

Examples of different figures of note:
Figures sur la portée
  • Whatever the key used, the principles are the same rating : from the notes associated with the key, we write the sequence of notes up or down, alternating lines and spaces. In addition to the five lines and four blank lines, it also uses the spaced below the first line, and spaced above the fifth line.
For example, for the second line treble clef :
note repère

Lines and spaced further

Above and beyond the scope, it has lines and additional blank lines, whose function is to expand the scope occasionally. The number of lines and additional blank lines may be used is in principle unlimited.

For example, for the second line treble clef :
Lignes et interlignes supplémentaires

Signs octave

The octave is a method of scoring to offset a fragment consisting of a melodic octave to include it in the center of the span. The octave, reducing the number of lines and extra line spacing, thus allows easy reading. So that the piece is played, however, to the desired height, we wrote "8 va alta" - an octave higher - or "8 va bassa" - an octave lower - at the beginning of the octave. The end of the fragment offset is usually indicated by the indication "loco" - return to real heights. However, if the fragment in question is relatively short, it defines it simply by dots.

For example :

The octave in music

The etymology of the word octave just music: it takes eight grades to have a frequency twice as high.
Indeed, the one to play in tune, it must produce a frequency of 440 Hz to play the octave above, it is necessary to produce a frequency of 880 Hz, ie, exactly twice.
In music, an octave is the interval between two sounds whose fundamental frequency of one is twice the frequency of the other. Divided into several sub-intervals, it allows to define the ranges.


In western music, solfeggio (or music theory) is the study of elements to read, write, play or sing a score. The ultimate goal of reading music is to hear a musical work, its orchestration and its interpretation, no other medium that its interior hearing.
