In music Music is an art form whose medium is sound. Common elements of music are pitch , rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike), "(art) of the Muses", dynamics normally refers to the volume Loudness, a subjective measure, is often confused with objective measures of sound pressure such as decibels or sound intensity. Filters such as A-weighting attempt to adjust sound measurements to correspond to loudness as perceived by the average human. However, as the perception of loudness varies from person to person it cannot be universally of a sound Sound is a travelling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations or note The term "note" can be used in both generic and specific senses: one might say either "the piece Happy Birthday to You begins with two notes having the same pitch," or "the piece begins with two repetitions of the same note." In the former case, one uses "note" to refer to a specific musical event; in the, but can also refer to every aspect of the execution of a given piece, either stylistic (staccato, legato etc.) or functional (velocity). The term is also applied to the written or printed musical notation used to indicate dynamics. Dynamics do not indicate specific volume levels, but are meant to be played with reference to the ensemble as a whole. Dynamic indications are derived from Italian Italian ( italiano , or lingua italiana) is a Romance language spoken by about 60 million people in Italy, and by another 10 million Italian descendants in the world, making it spoken by a total of 70 million native speakers. It is also spoken by an additional 125 million people as a foreign language. In Switzerland, Italian is one of four words.
