| This lesson is part of the Fundamentals of Sound & Music module. |
Objectives
- Student will understand the basic nature of sound as vibration and how it propagates through a medium.
- Student will understand the concepts of frequency/amplitude and how they relate to pitch, loudness, and the media through which sounds travel.
- Student will be able to describe sound based on a visual representation on a spectrogram, time-frequency graph, or oscilloscope trace.
- Student will identify the basic components of musical sound: pitch (melody vs. harmony), texture, rhythm/meter (duration), timbre.
