A sometimes-useful measure is how conventional the rhythms and melodies are. Most rock, pop, blues, dance music etc., is based around a simple 4/4 or 2/4 backbeat, (occasionally 6/8 or 3/4), and use either a blues scale or a diatonic scale.

This metal hardness chart organizes different types of metal using the Mohs hardness scale, a metric used by scientists to determine the scratch resistance of different minerals. With diamond at the top of the scale at a score of 10, elements and alloys can fall along the metal hardness scale from 10 (the most scratch-resistant) to 1 (the softest).

This mineral has a hardness of 7 to 7.5 on the Mohs scale. That means the quartz in dust makes those particles hard enough to actually remove the finish from your car and the polish from your table. Dust can even cut glass. Everyday hazards such as this make gemstone hardness an important consideration when designing and wearing jewelry.

After studying chemistry, mathematics and physics at the University of Halle. He went on to study at the Mining Academy in Freiberg, Saxony where he was influenced by his

Mohs hardness, rough measure of the resistance of a smooth surface to scratching or abrasion, expressed in terms of a scale devised (1812) by the German mineralogist Friedrich Mohs. The Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness. To give numerical values to this physical property,

The Mohs' hardness scale was developed in 1822 by Frederich Mohs. This scale is a chart of relative hardness of the various minerals (1 - softest to 10

Mohs' scale of mineral hardness is named after Friedrich Mohs, a mineralogist.Mohs scale is ordered by hardness, determined by which minerals can scratch other minerals.. Rocks are made up of one or more minerals. According to the scale, Talc is the softest: it can be scratched by all other materials. Gypsum is harder: it can scratch talc but not calcite, which is even harder.
