Dynamics: The Heart of Sound...

Most people are familiar with the basic elements of music, that of pitch, rhythm, and tone quality. As a musician matures, they must learn other important factors. The most important of these is dynamics. For the sake of the layman, dynamics in music are the variations in loud and soft. Student musicians sometimes fail to recognize the importance of these qualities. This may be a result of listening to a lot of popular music on radio. In addition to the fact that many pop performers use very little difference in dynamics, it is reinforced by the use of equipment in radio stations to level the dynamic contrast to make it easier to match various recordings to a constant volume level. This can be demonstrated by comparing a popular recording to a “classical” recording with a high degree of dynamic variation, such as Holst’s The Planets Suite. Dynamics really come in two ways. The first, more well-known way, is the overall level of a passage of music. These may be marked f (forte or loud), p (piano or soft), modified slightly with an m (mezzo or moderate) in front, or compounded by multiple indications like ff (fortissimo). Changes are made by indicating a new level for a sudden change, or with the description crescendo or decrescendo to indicate a gradual change. Usually when people talk about dynamics, it’s this type that they mean. Unlike many other things in the notation of music, the levels are entirely relative. Forte is not assigned a specific decibel level, and varies depending on the style of music, the type of ensemble, the importance of the passage, and ultimately the artistic intent of the composer or conductor or performer. The issue is further complicated by large variations in the intent...
