Pronunciation: [ˈɒktɪv spˈiːsiːz] (IPA) 
Octave species, also known as "octave classes," refer to a group of pitches that span a full octave and share the same pitch class. The most well-known example of an octave species is the major scale, which consists of eight notes that repeat at the octave. Other common octave species include the natural minor scale, the blues scale, and the whole tone scale.
