A Dictionary of Music and Musicians/Voces Hammerianæ

VOCES HAMMERIANÆ. A term applied to the syllables Do, Re, Mi, Fa, Sol, La, Si—the modern amplification of the series used, in the 11th century, by Guido d'Arezzo. The name is of German origin; and was invented in honour of Kilian Hammer, Organist of Vohenstraus, who first introduced the amplified system to German Musicians, about the middle of the 17th century. [See Solmisation.]
