Sesquialterate, greater imperfect, which is where the breve, when pointed, contains three measures, and without any point, two.
Sesquialterate, less imperfect, a triple, where the semibreve with a point contains three measures, and two without.
Sesquialterate, in Arithmetic and Geometry, is a ratio between two numbers, or lines, &c, where the greater is equal to once and a half of the less. Thus 6 and 9 are in a Sesquialterate ratio, as also 20 and 30.
