[Illustration: FIG. 33.
On the wooden board, round spaces are cut out
corresponding to the notes. Inside each of the spaces there is a figure.
On one side of each of the discs is written a number and on the other the
name of the note. They are fitted by the child into the corresponding
places.]
[Illustration: FIG. 34.
The child next arranged the discs in the notes cut out on
the staff, but there are no longer numbers written to help him find the
places. Instead, he must try to remember the place of the note on the
staff. If he is not sure he consults the numbered board (Fig. 33).]
[Illustration: FIG. 35.
The child arranged on the staff the semitones in the
spaces which remain where the discs are far apart: do-re, re-mi, fah-soh,
soh-la, la-ti. The discs for the semitones have the sharp on one side and
the flat on the other, e.g., re[sharp]-mi[flat] are written on the
opposite sides of the same disc.]
[Illustration: FIG. 36.
The children take a large number of discs and arrange them
on the staff, leaving uppermost the side which is blank, i.e., the side
on which the name of the note is not written. Then they verify their work
by turning the discs over and reading the name.]
[Illustration: FIG. 37.
The double staff is formed by putting the two staves
together. The children arrange the notes in the form of a rhombus.]
[Illustration: FIG. 38.
The two boards are then separated and the notes remain
arranged according to the treble and bass clefs. The corresponding key
signatures are then placed upon the two different staves.]
