Pseudo-octave: Stretched octave & Overview

In music theory, a pseudo-octave, pseudooctave, or paradoxical octave is an interval whose ratio of frequencies is not exactly the 2:1 = octave:tonic expected for perfectly harmonic pitches, but slightly wider or narrower in pitch – for example 1.98:1, 2.01:1, or even as large as 2.3:1. The pseudo-octave is nevertheless perceived as if it were equivalent…
