Example 3: Find the mean proportional between 0.08 and 0.18? For example, the interval from C to E is a major third, as the note E lies four semitones above C, and there are three staff positions from C to E. Diminished and augmented thirds span the same number of staff positions, but consist of a different number of semitones. The sum of the terms of the ratio = 7 + 5 + 3 + 4 = 19. We will also define what we mean by the fourth proportional, the third proportional and the mean proportionals. For example, if we have any four numbers or quantities that we represent as ‘a’, ‘b’, ‘c’, and ‘d’ respectively, then we may write the proportion of these four quantities as: //
