In [[JustIntonation|just intonation]], Isoharmonic chords are build by successive jumps up the [[OverToneSeries|harmonic series]] by some number of steps. Since the harmonic series is arranged such that each higher step is smaller than the one before it, all isoharmonic chords have this same shape -- with diminishing step size as one ascends. ~~It happens that all~~ isoharmonic chords are equal-hertz chords ~~(but~~ not all equal-hertz chords are isoharmonic chords). An isoharmonic "chord" may function more like a "scale" than a chord (depending on the composition of course), but I will use the word "chord" on this page for consistency.
