Musical Dynamics
Daniel Stevens
Sound waves have two distinct qualities: their frequency, which determines pitch, and amplitude, which determines the intensity of the sound. Musicians typically call the intensity of the sound its dynamic, and like other elements discussed in this chapter, it is easy for musicians to take dynamics for granted. After all, many musicians have been learning to plan piano and forte since their very first lesson.
Nevertheless, dynamics are an impactful element of sounds. Sudden changes in dynamics can startle and scare, and the combination of different dynamics can create a unique sense of spatiality within a piece, even if all the parts are played by the same performers (such as in a solo piano piece). In the 20th century, composers applied serial techniques (a specific kind of musical ordering) to dynamics, such that specific sounds would be performed along a broad dynamic spectrum from ppppp to fffff. Although we may sometimes take the dynamics of a piece for granted, they are nevertheless an iconic element of some pieces. Imagine, for instance, Johannes Brahms’s Lullaby or John Williams’s Jaws motive performed at ff, or Led Zepplin’s “Black Dog” sung at a mellow mp. In fact, it is difficult to imagine almost any piece of music for which its dynamics are not an integral part of its expressive content.
Listening carefully to dynamic contrasts is critical for both performers and conductors. Performers can use dynamics to shape phrases, delineate musical sections, and create express effects (e.g., surprise, quietude, intensification). Conductors and performers alike must shape dynamic levels across multiple parts to create balance, textural clarity, and effective voicing.
In addition to the activities below, we encourage you to be mindful of dynamic usage, shaping, and contrast as you perform and listen to music, whether in solo or ensemble settings. Developing an aural awareness and expressive control with regard to dynamic range can enhance your skills as a performer and listener.
Activity: Describe the use of dynamics in the performance of a musical work.
Goal: Increase awareness of the role of dynamics in shaping music perception and interpretation.
Instructions:
- Choose a movement from the playlist below.
- Describe how dynamics are used by the composer and/or performer to:
- amplify musical form
- delineate or contrast thematic and motivic ideas
- manipulate timbre
- create an overall expressive contour
Activity: Manipulate dynamic relationships while performing a musical passage.
Goal: Expand and explore the dynamic range of a musical passage.
Before you start: you will need a recording device
Instructions:
- Choose a piece of music that you are currently learning.
- Study the dynamics on the score, but also make note of how you are already using dynamics to shape musical phrases, sections, or the piece as a whole. Also note any areas where you are using dynamics to balance musical parts within the texture, voi
