In music, solfège (French pronunciation: ​[sɔl.fɛʒ]), solfeggio (Italian pronunciation: [sol.fed͡ʒo]) or solfeo (Spanish pronunciation: [sɔl.fɛo]) (also called sol-fa, solfedge, or solfa) is a music education method used to teach pitch and sight singing. Solfège is taught at every level of music education, from primary through graduate level university study.Many music education methods use solfège to teach pitch and sight-reading, most notably the Kodály Method.The study of solfège enables the musician to audiate, or mentally hear, the pitches of a piece of music which he or she is seeing for the first time and then to sing them aloud. Solfège study also improves recognition of musical intervals (perfect fifths, minor sixths, etc.), and strengthens the understanding of music theory. Solfège is a form of solmization, and the two terms are sometimes used interchangeably.The technique of solfège involves assigning the notes of a scale a particular syllable, and then practicing by singing different note sequences using these syllables. The sequences gradually get more difficult in terms of intervals and rhythms used.The seven syllables commonly used for this practice in English-speaking countries are: do (or doh in tonic sol-fa), re, mi, fa, sol (so in tonic sol-fa), la, and ti. In other languages, si is used (see below) for the seventh scale tone.There are two ways of applying solfege: 1) fixed do, where the syllables are always tied to specific pitches (e.g. "Do" is always the pitch "C") and 2) movable do, where the syllables are assigned to different pitches based on musical context.
