A word a day week
si
SI · one spoken or sung note · 7
- yes
- willingly
At the top of the seven-note ladder, si is assent: yes, agreed, willingly.
Seven-note spelling
Say it, play it, flash it
- si7 · violet
The seventh one-note word answers yes and can also carry the sense willingly or agreed.
Gajewski’s grammar also shows a three-line staff and a special shorthand. Here, the notes appear on a modern treble clef. The C-major pitches are a playback choice; Solresol does not require absolute pitch.
Tiny sentence
Si!
yes
“Yes!”
A complete one-word utterance. English-language solfège often calls the seventh note ti; historical Solresol uses si.
There is a short pause between words. The C-major pitches are a playback choice.
Receipts
Sources and cautions
The historical grammar and Sudre-derived dictionary use si, not the later English solfège label ti.
