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 movable (10[1])systems, fixed systems (10[1])named for this sound set it to the tonic of a C major scale. (10[1])This sound (10[1])is the first title word of a song from The Sound of Music, in which Maria (10[1])follows (10[3])a (10[1])homophone (10[1])of this sound with the lyric “a (10[1])deer, a female deer.” For 10 points, name this first syllable in the (10[1])solfège (“SOLE-fezh”) system, where it precedes re (“ray”) and mi ■END■
