English Wikipedia has an article on:
4:5:6:7, the harmonic seventh chord, is a tetrad in 7-limit harmony. It is often used as a tuning target for the dominant seventh chord in barbershop music (→ Wikipedia: Harmonic seventh chord #Barbershop seventh ), and also for the German sixth chord in septimal meantone.
It is a dyadic chord in the 7-odd limit, with its most complex interval a 7/5 tritone. It is the octave-reduced version of the first four odd harmonics, 1:3:5:7, or the first eight harmonics, 1::8.
