A frequency for a weighted cantilever beam. The determining factors of the length [L] are: the frequency of the tone desired, the modulus of elasticity [E] and density [ρ] of the material used, the base [b] and height [h] of the cantilever beam, and the mass [M] at the end of the cantilever beam. Carefully balancing these factors produce the lengths of the cantilever beams with the desired tones. Due to the nature of the Equation being quartic, MICROSOFT EXCEL was utilized to balance the equation, with respect to the determining factors, to produce multiple tone's corresponding lengths within a certain allowable frequency tolerance. The properties are shown in the tables in FIG. 18. The frequency tolerance is determined based on what tone is required and how large and forgiving the frequency is (e.g., the tone of tone C1, with a frequency of 32.7 Hz is less forgiving than the tone C4 with a frequency of 261.6 Hz. The tone C4 is more forgiving due to the frequency being larger). The material of the sound comb 70 is preferably 1095 spring steel, which was selected for its specific modulus of elasticity and its density.
