英语百科

Interval ratio

3-limit 9:8 major tone  Play .
5-limit 10:9 minor tone  Play .
7-limit 8:7 septimal whole tone  Play .
11-limit 11:10 greater undecimal neutral second  Play .

In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth (for example C to G) is 3:2 ( Play ), 1.5, and may be approximated by an equal tempered perfect fifth ( Play ) which is 2 (about 1.498). If the A above middle C is 440 Hz, the perfect fifth above it would be E, at (440*1.5=) 660 Hz, while the equal tempered E5 is 659.255 Hz.
