harmonikusanlike

Harmonikusanlike is a neologism used in theoretical discussions of music theory and signal processing to describe signals, timbres, or structures that resemble harmonic properties without strictly forming a harmonic series. The term blends the notion of harmonics with the suffix -like to denote similarity rather than exact equivalence.

In practice, harmonikusanlike signals are characterized by spectra where partials occur near integer multiples of a fundamental frequency but show deviations due to nonlinearities, inharmonicity, modulation, or spectral smearing. This concept is often invoked to describe certain vocal timbres, percussive spectra, or digitally synthesized sounds where the harmonic impression persists even as precise harmonic alignment shifts. It also serves as a useful framework for discussing quasi-harmonic phenomena that do not fit neatly into classical Fourier analysis.

Theoretical groundwork emphasizes the overlap with inharmonicity, partial tracking, and nonlinear time-series analysis. Harmonikusanlike signals may exhibit dynamic pitch drift, partial interactions, or micro-modulations that preserve an overall harmonic perception without stable, integer-multiple relationships. Analytical tools commonly employed include spectral centroid measurements, partial tracking algorithms, and nonlinear dynamical methods to capture evolving harmonic-like structures.

Usage and reception remain largely academic or pedagogical, with the term appearing in speculative discussions rather than as a standardized concept in peer-reviewed literature. Examples cited include bowed-string spectra with slight inharmonicity, piano overtones detuned by mechanical factors, and synthesized sounds where partials modulate over time to maintain a quasi-harmonic impression.
