Science of Music Activity
- Download Audacity, a free internet program for recording and mixing sound.
- Open the program, and use a microphone and a musical instrument or voice to record a few notes. You may also record music with other software, and then open the file in Audacity for editing. It may be necessary to convert the file first to a format read by Audacity. Converting files is easy with a program such as DVDVideoSoft's Free Audio Converter.
- Explore the sound wave, using the zoom function (magnifying glass icon). What does the wave look like?
- Use these steps to compare several sound waves. Try comparing different notes or different instruments. Or, try comparing an instrument to voice.
Example: Flute Solo
The following flute solo was recorded and opened in Audacity.
Using the zoom function several times provides more detail, but the sine waves are still obscured.
Further use of the zoom function reveals the sine wave.
Individuals interested in comparing the sound waves of musical instruments may benefit from the following publications from Schottenbauer Publishing, which, as a group, contain samples from typical Western strings, woodwinds, brass, percussion, and keyboard instruments, plus voice and conducting:
- Where Does Sound Come From? A multi-volume series with data on sound
- The Science of Music: An Anthology of Graphs A concise collection of graphs illustrating central concepts
- Ear Training: Tone Quality A series of multimedia containing sound samples labeled with verbal descriptions of tone quality, for training and/or testing
Other science of music publications from the same publisher include:
- How Do You Play That Thingamabob? The Science of Music Performance A multi-volume series on the forces and motion required for producing sound
- Bow Science & Exercises for the Violin & Viola A series of books containing practical science, applied directly to exercises
These educational tools can be integrated into music education curricula from late elementary school through high school and college/university.
