ti

The word “ti” means the seventh note of a major musical scale in solfège (do, re, mi, fa, sol, la, ti). In plain terms, the note right before the octave completes in "do-re-mi" singing.

“Ti” is pronounced tee (/tiː/ in IPA).

Here is “ti” used in a sentence: “She sang the scale up to ti before hitting the final do.”

“Ti” is a noun.

The word “ti” dates back to around 1812. Coined in 1812 by music teacher Sarah Anna Glover, replacing an earlier syllable "si" so every solfège note began with a different letter.

“Ti” is a fairly common word in modern English.

Ti is the seventh note of a major musical scale in solfège, coming after do, re, mi, fa, sol, and la, and just before the scale returns to do an octave higher. It typically has a strong pull back toward the tonic note, do, which gives it a tense, unresolved quality.

In fixed or movable solfège, ti is the standard spelling for the seventh scale degree used in English-speaking countries, following the sequence do, re, mi, fa, sol, la, ti. Some older or European systems use si instead of ti for this note.

Ti is a semitone below the octave note, do, so it naturally creates tension that listeners expect to resolve upward. This leading-tone quality is why ti is often called the leading tone in music theory.
