However the inclined plane was the last of the six classic simple machines to be recognised as a machine. This is probably because it is a passive and motionless device (the load is the moving part), [ 21 ] and also because it is found in nature in the form of slopes and hills.
A wedge is a triangular shaped tool, a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular to its inclined
On May 15, 1932, a New Music Society concert in San Francisco [9] included – along with the premiere of Xanadu, a new work by Mildred Couper – a demonstration of Cowell's new instrument. According to some sources, the concert premiered Cowell's "Rhythmicana", in four movements with orchestra, and "Music for Violin and Rhythmicon".

The hand axe is the first example of a wedge, the oldest of the six classic simple machines, from which most machines are based. The second oldest simple machine was the inclined plane (ramp), [6] which has been used since prehistoric times to move heavy objects. [7] [8] The other four simple machines were invented in the ancient Near East. [9]

A composite rhythm is the durations and patterns (rhythm) produced by amalgamating all sounding parts of a musical texture. In music of the common practice period , the composite rhythm usually confirms the meter , often in metric or even-note patterns identical to the pulse on a specific metric level.
Pérotin, "Alleluia nativitas", in the third rhythmic mode. In medieval music, the rhythmic modes were set patterns of long and short durations (or rhythms).The value of each note is not determined by the form of the written note (as is the case with more recent European musical notation), but rather by its position within a group of notes written as a single figure called a ligature, and by ...
