The topic of this paper is an original form of logic called Tonal Logic. I have finally decided that my work will not be perfect or finished, but I am ready to offer, not a totality, but a synthesis on Tonal Logic. In the beginning of the paper, we give two well-defined hypothesis’ for laws of Tonal Gravity. The premise for these hypothesis’ involves two base cases which have a certain combinatorial property, that is the diatonic scale embedded in the chromatic scale, and the pentatonic scale embedded in the chromatic scale. The antecedent in the hypothesis involves the felt sensation of Tonal Gravity or the identification of a single tone which acts as the tonic. These well-defined hypothesis’ provide a deduction which enables the formulation of Tonal Logic. We proceed to define axioms of Tonal Logic, define Tonal Conservation, make a thesis statement on the phenomenon of emergence, apply Tonal Logic to describe mathematical objects, and finally, we form a cosmology out of the Tonal Logic. Having given form to Tonal Cosmology, we allow some deductions. The goal of this paper is not to thoroughly deliver a singular result. It is not to detail the hypothesis and experiment, not to perfect the axioms of tonal logic, not to show strict consistency with mathematics, nor fully detail a cosmology consistent with physics. The goal is to provide a synthesis on Tonal Logic which touches on all of these things and which may be expanded upon. I am an independent researcher, and most importantly, a musician. I have no references. I do reference well known equations in mathematics or physics at various points, however, the line of reasoning that I take, the hypothesis’ I offer, the Tonal Logic on display, and the application of this logic to number and cosmology is entirely original.
