The Science of Tone Quality

Tone quality is essential to all musical performance, but is not usually taught systematically in traditional music education. Rather than building an awareness of tone across instruments, individuals taking lesson in strings, woodwinds, brass may be offered individual suggestions for improving tone on their own instrument. Usually, their instrument is a student or intermediate model. If fortunate to take private lessons, students may also be provided exemplary tone quality examples from a specialist teacher performing on a professional instrument. In ensemble, students may be urged to "match tone quality" across their section, even when performing on different makes and models of instruments, which offer various tone quality. Options for learning about tone quality are even more limited on the piano, which is a common tool for music education.

How can educators and students learn about tone quality across the spectrum of band and orchestral instruments? A set of educational materials from Schottenbauer Publishing offer opportunities for learning multiple aspects of tone quality, including:

  • Identifying tone quality in band and orchestral instruments
  • Understanding the math and science of tone quality
  • Linking instrumental skills to auditory and math/science skills


To meet the first goal, the student can obtain recordings of multiple instruments, including common examples of good and poor tone quality. By listening carefully to comparison and contrast examples, and reading descriptions of each sample in words, students can develop and hone skills for identifying good tone. The multimedia set Ear Training: Tone Quality (Level 1) from MusicaNeo contains over 250 computer audio files with performance samples from common musical instruments, including strings, woodwinds, brass, and percussion. The series is accompanied by a brief lead sheet with exercises for improving tone quality, as well as an audio file with a computer realization of the exercises.  

To meet the second goal, the student can obtain graphs of tone quality samples from multiple instruments, including common examples of good and poor tone quality. By comparing these tone samples visually, and by reading descriptions of each sample in words, students can develop a mathematical/graphical understanding of good tone. The book series Where Does Sound Come From? and the anthology The Science of Music provide graphs with performance samples from common musical instruments, including strings, woodwinds, brass, and percussion. The graph below provides one example of the contents of these book series.



To meet the third goal, students can record their own musical performance on a microphone at the computer, and analyze the sound wave using a free program such as Audacity. Students can follow procedures from the free blog article Easy Science of Music Experiment to analyze their tone quality.

These educational tools can be integrated into music education curricula from late elementary school through high school and college/university, in classrooms, after-school enrichment programs, individual lessons, independent study, and/or homeschool. Additional information is available on the Schottenbauer Publishing website, and from the links below. A free pamphlet from the publisher is also available on the website.

The Science of the Harmonic Overtone Series

The harmonic overtone series is a basic concept in music education which explains how many musical instruments function. It is easiest to explain the harmonic overtone series with science and math. New teaching tools from Schottenbauer Publishing offer students a refreshing insight into the working of the harmonic overtone series. 

The graphs below are excerpted from Volume 1 of Where Does Sound Come From?, as well as a free pamphlet from the publisher. These graphs show graphs of sound pressure from two notes performed on a soprano recorder.



Discussion Questions
  1. Describe at least 2 differences between these two graphs.
  2. What types of information are contained in each graph?
  3. If possible, identify the frequency, wavelength, and/or amplitude of the wave in each graph.
  4. Is it possible to determine the pitch of the note from either graph? If so, how?
  5. Is it possible to determine the sound level (decibels) of the note from either graph? If so, how?
  6. Are these two graphs related in the harmonic overtone series? If so, how?
  7. Write a mathematical equation to describe the wave pattern in the bottom graph.

In addition to these graphs, a free YouTube video from the same publisher provides a brief lecture, as well as samples of the harmonic overtone series on flute, trumpet, trombone, and violin. 

Students may learn more about the harmonic overtone series in a multimedia training program titled Ear Training: Harmonic Overtone Series. Additional information is available on the Music Theory & Ear Training blog.

Additional graphs on the science of music and music performance can be found in a free pamphlet from the publisher, and the following book series by M. Schottenbauer, Ph.D. The books below contain data from common band and orchestral instruments, plus recorders, keyboard, voice, and conducting.
