It is also called a "septimal subminor seventh" -- the word "septimal" referring to the presence of a 7 as the highest prime in the ratio, and the word "subminor" referring to the harmonic seventh's narrowness compared with a traditional minor seventh (such as [[9_5|9:5]] or [[16_9|16:9]], [[12edo]]'s 1000-cent interval, or a minor seventh found in a meantone system). | <div style="width:100%; max-height:400pt; overflow:auto; background-color:#f8f9fa; border: 1px solid #eaecf0; padding:0em"><pre style="margin:0px;border:none;background:none;word-wrap:break-word;white-space: pre-wrap ! important" class="old-revision-html">Frequency ratio **7:4**, measuring approximately 968.8259064691249 [[Cent|cents]], has been given the name **"harmonic seventh."** It represents the interval between the 4th and 7th harmonics in the [[OverToneSeries|overtone series]].

7:4 has seen use in blues music, barbershop quartet music, and some musical traditions of the world, but has mostly not been recognized as a "consonance" in Western music theory. In most Just Intonation systems, the harmonic seventh is treated as a fundamental consonance in its own right, with its own distinct quality. | 7:4 has seen use in blues music, barbershop quartet music, and some musical traditions of the world, but has mostly not been recognized as a "[[consonance]]" in Western music theory.
