are attracted to each other by affinity. But the case is quite different with F and G and C and D. The second fifth above F is G (F a c, C e g), and G becomes the interval above F in the octave scale; and these two notes are neither attracted by affinity nor proximity nor gravitating tendency. F sinks away from G, being heavier, and under it; and G soars away from F, being above it, and lighter. In a similar way the second fifth above C is D (C e g, G b d), and D in the octave scale becomes the interval of the second above C, and C and D, like F and G, are not attracted by either affinity or proximity. C is heavier than D, and being under it would sink away from it; D is lighter, and being above it would soar away from it, and so neither are they attracted by gravitating tendency.
"All the bodies in the Solar System, in a general way, are attracted to the sun according to the Law of Masses; but all the satellites are attracted to their planets according to the Law of Distance. The subdominant and dominant chords in the Musical System, in a general way, are attracted to the tonic center; but each note in the octave scale is attracted to its nearest note by the Law of Proximity.
"The three notes of the dominant chord resolve by each note going to the next note upward - G soars to A, B to C, D to E. The three notes of the subdominant resolve by each note going to the next note downward - C sinks to B, A to G, F to E. The two upper notes of the dominant resolve into the tonic chord according to the Laws of Proximity and Specific Levity; and the two lower notes of the subdominant resolve into the tonic chord according to the Laws of Proximity and Specific Gravity. And in this way Nature, in chord-resolution, has two strings to her bow."
The System of Musical Sounds might be sketched as follows:- Three different notes having the simplest relations to each other, when combined, form a chord; and three of these chords, the one built up above the other, form a system.
Three times three are nine; this would give nine notes; but as the top of the first chord serves for the root of the second one, and the top of the second for the root of the third, in this way these three chords of three notes each are formed from seven different notes.
The middle one of these three chords is called the tonic; the chord above is called the dominant; and the chord below is called the subdominant. The order in which these three chords contribute to form the octave scale is as follows:- The first note of the scale is the root of the tonic; the second is the
