Remarks

These are periods, not frequencies: the hardware wants 2048 - 131072/Hz, and that is what the members hold. Higher values are higher pitches, and the spacing is not linear.

The enum is backed by ushort so a note used at a call site folds to a literal during lowering. There is no note table in ROM and no lookup at runtime: writing Note.A4 costs exactly what writing 1750 would.
