doremifasollatido

Doremifasollatido is the concatenation of the solfège syllables used to denote the notes of a diatonic octave: do, re, mi, fa, sol, la, ti, do. It is commonly used as a mnemonic or teaching aid in Western music education to recall the ascending order of notes in a major scale. The syllables originate from solmization, a system developed in medieval Europe by Guido of Arezzo. The original hexachord syllables Ut, Re, Mi, Fa, Sol, La were later expanded: Ut was replaced by Do, and a seventh syllable, Ti (or Si in some languages), was added, giving Do–Re–Mi–Fa–Sol–La–Ti–Do. The single-word form doremifasollatido is not a formal technical term but a convenient way to reference the complete octave in one mouthful, and may appear in educational texts, word games, or trivia.

In practice, whether the syllables are taught as movable-Do or fixed-Do affects their pitch values. In movable-Do, do is the tonic of the key, so the sequence maps to the scale degrees rather than to absolute pitches; in fixed-Do, do corresponds to the note C. The word itself does not imply a key or tuning; it functions as a mnemonic for the standard major-scale sequence.
