The present invention relates to a calculation formula of Pythagorean tuning. It specifically comprises: inputting the initial frequency of the musical tuning, the number of downward tone and the number of upward tone through an input module, then calculating a corresponding frequency value by utilizing a calculation module, and outputting the corresponding frequency value through an output module. Compared with the traditional calculation method, the present invention has the advantages that: the present invention inputs the initial frequency of the musical tuning, the number of downward tone and the number of upward tone utilizing an input module, and calculates the corresponding frequency value by utilizing a calculation module, and outputs the corresponding frequency value through an output module, especially the obtained tone sequence can be played by various musical instruments through the sound output unit in the output module, which is convenient for music practitioners to use.

The embodiment relates to systems and methods structured to deliver acoustic and visual energies to be received by living beings, and, more particularly the energies received by living beings can be configured, composed, and/or designed to be delivered to address a plurality of conditions including enjoyment. The energies can be deployed by using various algorithms and can include tones, tuning, rhythms, sound waves, harmonies, melodies, chord progression and instrument arrangement to deliver the energies preferentially to different parts of a living being's body, such as but not limited to, right and/or left ears. The algorithms can include variations in Pythagorean tuning and just and pure intonation, monaural and binaural beats for brain wave entrainment, Solfeggio Frequencies, Fibonacci Sequencing, and/or carrier waves and isochronic tones.

At least one electronic signal is converted into at least one electromagnetic field, where the electronic signal may be created or modulated by environmental, interactive, and programmed inputs. The at least one electromagnetic field vibrates a ferromagnetic element creating an acoustic sound and optionally a transducer converts the vibration into an electronic signal for processing.
