MUSC 2100 Lecture 4: Frequency and Pitch
Document Summary
We"ve seen that all frequencies in a spectrum contribute to our perception of pitch and especially to tone color (or timbre) Remember, however, that the name for a musical pitch (middle c or c4, for instance), which is usually tuned to about 261. 6 hz gives us no information about the spectrum of the sound. In sound mixing, therefore, we need to be aware of the full spectrum of any particular instrumental. note in order to avoid potential conflicts with other instruments. Each component (fundamental, partial and harmonic) of a sound will have its own envelope and maximum amplitude level. The representation of a periodic sound or waveform as a sum of fourier components (i. e. pure sinusoidal waves) According to the fourier theorem, periodic sound may be shown to consist of sine waves in the harmonic series, where the fourier coefficients give the amplitude and phase angle of each component. Timbre (or tone color) is a qualitative description of sound.
