This sound may have been named after a Florentine humanist who modified a system developed by Guido of Arezzo from the hymn “Ut queant laxis” (“oot QUEE-awnt LAK-sees”). A system developed in Norwich inspired John Curwen to describe this sound as “firm.” In the Kodály (“koh-DIE”) method, this sound is represented by a closed fist. In contrast to (10[1])movable systems, fixed systems named for this sound set it to the tonic of a C (10[1])major scale. (10[1])This sound is the first title word of a song from The Sound of Music, in which Maria follows a homophone (10[2])of this sound with the lyric “a deer, a female (10[1])deer.” For 10 points, name this first syllable in the solfège (“SOLE-fezh”) system, where it precedes re (“ray”) and mi ■END■
