The concept in music

In the field of music, a clef is a sign that is written at the beginning of the staff to determine the name of the notes that will appear next. The most commonly used clef in music is the treble clef.

The function of a musical clef is to locate the person who plays a certain melody within a tonality, using those notes that are harmonically associated with each other and associating them with the spaces and lines of the staff.

There are many possibilities for clefs and positions on the staff, yet only seven of these are used. It is important to point out that for a melody plotted on a staff to have meaning and coherence, it must contain a clef at the beginning; Furthermore, it may change throughout the piece. When modulations are carried out, it is not necessary to change the key, if it will return to the original key, but if the change is complete and will be maintained for the rest of the work, it is necessary to change the key that is used.
