AIPW Summary: A music synthesizer that provides a constant beat across a range of tones. The beat frequency is independent of pitch or octave. For those of you who thought music and math were different, this invention shows otherwise by deriving the beat frequency according to an equation. This patent is rather short, so there’s not much to discuss.
