Music, music synthesizer. 12-law
1. piano chord of g we commonly used chord G7. no chords g. why?
2. in music theory chord G7 5724 composed tone 2-tone only 574 omitted and why? (Five-seven chords can save five tone and acoustic)
In 12 equal temperament mid frequency G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz
In just intonation mid frequency G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz
D in just intonation tuning two frequencies. one from another by the Dm chord g chord 297.00Hz 293.33Hz
G4=396 D=396x3/2/2=297 (piano without the frequency)
A4=440 Dx3/2=440 D=293.33 (5.12 equal temperament. pure D=293)
Current D4 g chord sound =293.33Hz not meet harmonic. D4 only joined harmonic the g chord does not sound =297Hz harmony
Chord G7 meet harmonic. therefore experienced composers at the strings often use chord G7 chords instead of g.
