Fifteenth
In music, a fifteenth or double octave, abbreviated ''15ma'', is the interval between one musical note and another with one-quarter the wavelength or quadruple the frequency. It has also been referred to as the bisdiapason. The fourth harmonic, it is two octaves. It is referred to as a fifteenth because, in the diatonic scale, there are 15 notes between them if one counts both ends (as is customary). Two octaves (based on the Italian word for eighth) do not make a sixteenth, but a fifteenth. In other contexts, the term ''two octaves'' is likely to be used. For example, if one note has a frequency of 400  Hz, the note a fifteenth above it is at 1600 Hz (''15ma'' ), and the note a fifteenth below is at 100 Hz (''15mb'' ). The ratio of frequencies of two notes a fifteenth apart is therefore 4:1. As the fifteenth is a multiple of octaves, the human ear tends to hear both notes as being essentially "the same", as it does the octave. Like the octave, i ...

Fifteenth (tax)
The history of the English fiscal system affords the best known example of continuous financial development in terms of both institutions and methods. Although periods of great upheaval occurred from the time of the Norman Conquest to the beginning of the 20th century, the line of connection is almost entirely unbroken. Perhaps the most revolutionary changes occurred in the 17th century as a result of the Civil War and, later, the Glorious Revolution of 1688; though even then there was no real breach of continuity. The primitive financial institutions of early England centred round the king's household. In other words, the royal preceded the national economy in importance. Revenue dues collected by the king's agents, rents, or rather returns of produce from land, and special levies for emergencies formed the main elements of the royal income which gradually acquired greater regularity and consistency. There is, however, little or no evidence of what modern governments recogni ...
