Etymology

Si is the name of the seventh note in the 'do, re, mi' scale and is used in many languages instead of 'ti'. One popular story says si came from the first letters of the Latin phrase Sancte Ioannes ('Saint John') in a church hymn, so you can remember si as the extra syllable added to finish the scale.
