Choose a textile, or any design with a variety of spaces, and try notan‐
effects with tones from the scale. The object is to discover a fine notan‐
scheme of values, and by using the scale one is assured of definite
intervals. If the notes are mixed in quantity, they may be tried upon a
half‐dozen tracings at once, from which the best should be chosen.
Remember that the scale‐work is only an exercise to help toward clarity of
tone, and to encourage invention. Harmony of dark‐and‐light does not
depend upon fixed intervals, nor will the composer adhere to any scale in
his original creative work.
Some results of this exercise are shown in No. 58, page 91.
