THE READING AND WRITING OF MUSIC
Material: In "The Children's House" the musical staff is introduced by means of a board painted green with the lines in bas relief. On each line and in each space representing the octave to which the sounds of the bells respectively correspond, is a small circular indenture, or socket, into which the disk for each note may be inserted. Inside each indenture is written a number: 1, 2, 3, 4, 5, 6, 7. The disks used in this exercise have a number written on the lower face and the name of a note on the upper: for instance, 1, do; 2, re; 3, mi; 4, fa; 5, sol; 6, la; 7, si:
do—re—mi—fa—sol—la—si—do.
This device enables the child to place the notes on their respective lines without making any mistakes and to examine their relative positions. The indentures are so arranged as to show an empty space wherever a semi-tone appears:
