Defined in technical language, spectral music is an acoustic musical practice where compositional decisions are often informed by sonographic representations and mathematical analysis of sound spectra, or by mathematically generated spectra.
In Western music, the term chroma feature or chromagram closely relates to twelve different pitch classes. Chroma-based features, which are also referred to as " pitch class profiles ", are a powerful tool for analyzing music whose pitches can be meaningfully categorized (often into twelve categories) and whose tuning approximates to the equal ...

Do spectral analysis to obtain the frequency components of the music signal. Use Fourier transform to convert the signal into a spectrogram. (The Fourier transform is a type of time-frequency analysis.) Do frequency filtering. A frequency range of between 100 and 5000 Hz is used. Do peak detection. Only the local maximum values of the spectrum ...
Smalley defines three different spectral typologies that exist in what he calls the noise-note continuum. This continuum is subdivided into three principal elements: the noise. the node (an event having a more complex texture than a single pitch). the note, which is in turn subdivided into note, harmonic spectrum and inharmonic spectrum.
Music theory analyzes the pitch, timing, and structure of music. It uses mathematics to study elements of music such as tempo, chord progression, form, and meter. The attempt to structure and communicate new ways of composing and hearing music has led to musical applications of set theory, abstract algebra and number theory.
MUSIC is a generalization of Pisarenko's method, and it reduces to Pisarenko's method when = +. In Pisarenko's method, only a single eigenvector is used to form the denominator of the frequency estimation function; and the eigenvector is interpreted as a set of autoregressive coefficients, whose zeros can be found analytically or with ...
When considered as part of a whole spectrum, a pure tone may also be called a spectral component. In clinical audiology, pure tones are used for pure-tone audiometry to characterize hearing thresholds at different frequencies. Sound localization is often more difficult with pure tones than with other sounds. [2] [3]
