What does di mean?
"Di" is a syllable drawn from the extended, chromatic form of solfège, the system musicians use to name the notes of a scale while singing. In standard solfège the seven degrees of the major scale are sung as do, re, mi, fa, sol, la, and ti. Chromatic solfège adds extra syllables for the notes between them, so that each pitch in an octave has a distinct name. Within this scheme, "di" names the raised second degree of the scale — in other words, a sharped "re," such as D-sharp when the tonic is C. Singing "do, di, re" therefore traces the first three half-steps of an ascending chromatic scale. The term belongs almost entirely to the world of music pedagogy: it appears in ear-training classes, vocal warm-ups, and sight-singing exercises, and it is rarely met outside those settings. For learners of relative pitch, however, such syllables are genuinely practical, giving every sharp and flat its own singable label instead of forcing singers to describe altered notes indirectly.
noun"Di" is a syllable used in the extended (chromatic) system of solfège, representing the raised second degree of the scale — that is, "re" sharpened by a semitone, as in D-sharp.
- The chromatic solfège syllable denoting a raised second scale degree (sharpened "re", e.g. D-sharp).
"In chromatic solfège, the ascending scale runs do, di, re, ri, mi."
"The choir warmed up by singing do, di, re up the chromatic scale."
"Her ear-training teacher insisted on "di" rather than calling the note D-sharp."
Rarely pluralized in practice; if needed, regular plural applies.
"The exercise moved through several dis before resolving back to re."
Every sharp you sing has its own private name — and the one for D-sharp is simply "di."

Etymology of di
The syllable "di" comes from the chromatic expansion of solfège, a naming system whose core syllables derive from medieval Latin via the Guidonian hexachord. The additional syllables for sharps and flats were developed within the Italian solfège tradition to give every chromatic pitch a distinct name; "di" was formed by altering the vowel of "re" to signal a raised version of that degree. It entered common use in music teaching through European conservatory practice and later Anglo-American methods such as Kodály-based ear training.
How di is actually used
Highly specialized vocabulary: encountered almost exclusively in music education contexts, particularly in movable-do and chromatic (extended) solfège systems used for sight-singing and ear training. Rarely used outside that setting.
Easily confused with di
"Die" means to cease living or a small cube used in games, whereas "di" is only a musical solfège syllable.
"Dye" is a substance used to color materials or the act of coloring them; "di" belongs exclusively to musical notation.
