The following table provides the frequencies of four octaves of the tempered musical scale (1/2 step between notes) rounded in integers:
Note 1: Standard Pitch is based on the tone "A" of 440 Hz. With this standard, the frequency of Middle C should actually be 261.626 Hz.
Note 2: The entire Musical Scale from C0 (16.35 Hz) to D9# (9,956.06 Hz) are available as presets in the “Make Waves” Generator (Edit Menu).
