Before starting work at the keyboard, consideration should be given to the structure of the modern diatonic scale, which contains the material from which the music is to be evolved.
The key should be regarded as a tone-family, as a collection of different tones more or less nearly related to one another. Upon this relationship of the individual tones of the scale will depend the relationship of chords, and of the melodies which will be derived from them.
The first member of the tone-family is, of course, the keynote, or tonic. Its nearest relation is its perfect fifth. This is taken because it represents the simplest vibrational ratio, i.e., 2:3. The octave (1:2) is evidently of no assistÂance in this connection, because our ears have decided that the two tones which it represents are, for practical purposes,, identical.
