8/1
| Interval information |
three octaves
[sound info]
8/1, the 8th harmonic, is the harmonic past 7/1 and before 9/1. It is equal to a stack of three octaves.
Name
Naming this interval is complicated because, analogously with tritave and pentave, the expected derivation would be "octave", but that is already the name for 2/1. Hence, no name of that format is given for 8/1.
