 In the major Romance and Slavic languages, the syllables Do, Re, Mi, Fa, Sol, La, and
Si are used to name notes the same way that the letters C, D, E, F, G, A, and B are used to name notes in English.For native speakers of these languages, solfège is simply "singing the names of the notes", omitting any modifiers such as "sharp" or "flat" in order to preserve the rhythm.This system is called fixed do and is used in Spain, Portugal, France, Italy, Belgium, Romania, Latin American countries and in French-speaking Canada as well as countries such as Bosnia and Herzegovina, Croatia, Russia, Serbia, Poland, Ukraine, Georgia, Bulgaria, Greece, Armenia, Albania, North Macedonia, Mongolia, Iran, Israel, the Arab world, Turkey, and Taiwan where non-Romance languages are spoken.
