In music, the term note has two primary meanings:
Notes are the "atoms" of much Western music: discretizations of musical phenomena that facilitate performance, comprehension, and analysis.
The term "note" can be used in both generic and specific senses: one might say either "the piece 'Happy Birthday to You' begins with two notes having the same pitch," or "the piece begins with two repetitions of the same note." In the former case, one uses "note" to refer to a specific musical event; in the latter, one uses the term to refer to a class of events sharing the same pitch.
Two notes with fundamental frequencies in a ratio of any power of two (e.g. half, twice, or four times) are perceived as very similar. Because of that, all notes with these kinds of relations can be grouped under the same pitch class. In traditional music theory pitch classes are represented by the first seven letters of the Latin alphabet (A, B, C, D, E, F and G) (some countries use other names as in the table below). The eighth note, or octave is given the same name as the first, but has double its frequency. The name octave is also used to indicate the span of notes having a frequency ratio of two. To differentiate two notes that have the same pitch class but fall into different octaves, the system of scientific pitch notation combines a letter name with an Arabic numeral designating a specific octave. For example, the now-standard tuning pitch for most Western music, 440 Hz, is named a′ or A4. There are two formal ways to define each note and octave, the Helmholtz system and the Scientific pitch notation.
Que te dit ton coeur, lui qui ne demande qu'à voir
Au-delà des leurres, des fruits du hasard
Il est des mystères, des songes qui parfois t'égarent
Comme en une prière, il suffit de croire
Quel est le visage qu'adoptera ton destin
De son début jusqu'à la fin
Il suffit de croire
Observe les présages qui jalonnent ton chemin
Que te dit ton coeur, lui qui ne demande qu'à voir
Au-delà des leurres, des fruits du hasard
Refrain:
Entre les lignes, Kechef Touha
Y voir un signe, Min Al Rabba
Frôler les cimes, Fi Rouhouqa
Toucher l'infime, Al Tarika
Tout près de la Terre
Les yeux caressant le ciel
Cherchent l'éphémère en une étincelle
J'attends cette fleur
Ce doux don de l'éternel
Qui, dès qu'il se meurt
Sonne comme un rappel
Quel est le visage qu'adoptera ton destin
De son début jusqu'à la fin
Il suffit de croire
Observe les présages qu jalonnent ton chemin
Et t'expriment des lendemains
Sonnent comme un rappel
Refrain
Certaines vérités empruntent de singulières voix
Il suffit de croire
Fuit la cécité et soit éclairé dans tes choix
Dans les courbes que dressent tes pas
