In this section, we will examine certain physical characteristics of sound and will consider the ways in which sound is manifested in music. Beginning with the observations of Pythagoras, we will attempt to develop a basic understanding of the properties of sound waves, their use in harmonic and tonal-based systems of music composition, and the ways in which these phenomena are perceived. |
This is a complex area, and one which has occupied many theorists over the centuries. There are many (sometimes, very lengthy) tracts on the finer points of tuning and temperament, the details of which lay outside the scope of this session. More importantly, we will attempt to explore the ‘relative’ nature of musical correspondences, questioning the notion that western musical pitch relations are, in essence, a natural construct. |
This topic will therefore lay the foundation for a consideration and analysis of music encountered in subsequent sessions. |

- The Whipple Museum of the History of Science in Cambridge has a significant collection of nineteenth century acoustical apparatus, in particular several examples from the famous Parisian instrument maker Rudolph Koenig.
- The Online Interactive Harmonograph allows you to experiment with different ratio settings that produce graphic results.
- This very useful Interval Calculator from Dolmetsch Online enables you to convert from pitch to frequency to cents. Here is another one.
- The Research on Audiocommunication site, by Ernst Terhardt, contains many useful explanations of various aspects of the Perception of Auditory Pitch, and the Perception of Music Sound. You can download the whole site from here. Look particularly at the sections on Pitch perception, Definition of pitch, Spectral pitch, Virtual pitch, Absolute pitch, Affinity of tones, Octave equivalence, Musical consonance and Harmony.
- Ancient Greek Music contains computer-generated examples of extant melodies, together with sound examples from reconstructed instruments.
- The Tuning and Temperament Bibliography at the Huygens-Fokker Foundation Centre for Microtonal Music contains a huge list of texts and online articles relating to matters of tuning and temperament.
- The Physics Classroom section on Sound Waves and Music, whilst intended for American high school physics students, provides a good introduction to the properties of musical sounds for non-physicists.
