7. The F clef is made either thus, bass clef, or thus, old bass clef the dots being placed one on either side of the fourth line of the staff, which is the particular point that the clef marks. The C clef has also two forms, C clef and C clef.

8. The sharp is made with two light vertical strokes, and two heavy slanting ones, the slant of the latter being upward from left to right, . The sharp should never be made thus, #.

The double sharp is made either thus double-sharp or *, the first form being at present the more common.

9. The flat is best made by a down stroke retraced part way up, the curve being made without lifting pen from paper. The double flat consists of two flats,[3] ♭♭. The natural or cancel is made in two strokes, down-right and right-down, thus natural.

10. The tie usually connects the heads of notes, thus tie.

11. The dot after a note always appears on a space, whether the note-head is on a line or space. (See Fig. 5.) In the case of a dot after a note on a line, the dot usually appears on the space above that line if the next note is higher in position and on the space below it if the following note is lower.

Note.—Correct notation must be made a habit rather than a theory, and in order to form the habit of writing correctly, drill is necessary. This may perhaps be best secured by asking students to write (at the board or on ruled paper) from verbal dictation, thus: Teacher says,

"Key of B, three-quarter measure: First measure, DO a quarter note, RE a quarter, and MI a quarter. Second measure, SOL a quarter, LA a quarter, and SOL a quarter. Third measure, LA, TI, DO, RE, MI, eighths, stroked in pairs. Fourth measure, high DO a dotted half." Pupils respond by writing the exercise dictated, after which mistakes in the turning of stems, etc., are corrected. The pitch names may be dictated instead of the syllables if desired, and still further practice may be provided by asking that the exercise be transposed to other keys.


CHAPTER II

Symbols of Music Defined

12. A staff is a collection of parallel lines, together with the spaces belonging to them. The modern staff has five lines and six spaces, these being ordinarily referred to as first line, second line, third line, fourth line, and fifth line (beginning with the lowest); and space below (i.e., space below the first line), first space, second space, third space, fourth space, and space above.

The definition and discussion above refer more specifically to one of the portions of the "great staff," the latter term being often applied to the combination of treble and bass staffs (with one leger line between) so commonly used in piano music, etc.

13. The extent of the staff may be increased either above or below by the addition of short lines called leger lines,[4] and notes may be written on either these lines or on the spaces above and below them.

14. The lines and spaces constituting the staff (including leger lines if any) are often referred to as staff degrees, i.e., each separate line and space is considered to be "a degree of the staff." The tones of a scale are also sometimes referred to as "degrees of the scale."

15. A clef[5] is a sign placed on the staff to designate what pitches are to be represented by its lines and spaces. Thus, e.g., the G clef shows us not only that the second line of the staff represents G, but that the first line represents E, the first space F, etc. The F clef similarly shows us that the fifth line of the bass staff represents the first A below middle C, the fourth line the first F below middle C, etc.

The student should note that these clefs are merely modified forms of the letters G and F, which (among others) were used to designate the pitches represented by certain lines when staff notation was first inaugurated. For a fuller discussion of this matter see Appendix A, p. 101.

16. When the G clef is used the staff is usually referred to as the treble staff, and when the F clef is used, as the bass staff. Such expressions as "singing from the treble clef," or "singing in the treble clef," and "singing in the bass clef" are still frequently heard, but are preferably replaced by "singing from the treble staff," and "singing from the bass staff." Fig. 6 shows the permanent names of lines and spaces when the G and F clefs are used.[6]
