1728 E. Chambers Cycl. Si, in Music, a Seventh Note, added within this Sixty Years, by one le Maire, to the Six ancient Notes.

1797 Encycl. Brit. XII. 545 (note) A note which is a tone immediately above the tonic, as re in the mode of ut, and si in that of la, is termed a sub-tonic.

1850 T. Helmore Man. Plainsong iv. 22 The syllable si for the seventh sound of our octave was in more recent times added, from the initial letters of the closing words, Sancte Iohannes.

1876 J. Stainer & W. A. Barrett Dict. Musical Terms 313/2 Here was a sa for the seventh note of the scale; but..it was not employed. In later use, in order to mark another semitone by the vowel i (as in mi) sa was turned into si.
