ikkeresonante

Ikkeresonante is a term used in acoustics and contemporary music theory to describe a type of resonance that remains audible after the initiating excitation, without being tied to a single stable pitch. It refers to a resonant field whose energy is spread across a broad or dynamically evolving spectrum, rather than focused on a fundamental frequency.

Ikkeresonante is a neologism; its precise origin varies by author, but it is generally used to denote resonance phenomena that cannot be adequately described by pitch-centric concepts such as sustained tones or stable harmonics.

Physically, ikkeresonante may arise from nonlinear interactions in membranes or cavities, constructive feedback in acoustic systems, or long-lived energy storage in digital synthesis and reverberant networks. It tends to produce timbral textures and atmospheric continuity rather than serving as a melodic function anchored to a single pitch.

Analysts may study ikkeresonante with time‑frequency methods, focusing on decay envelopes, spectral occupancy, and changes in dominant components. The term is primarily used in experimental contexts and is not part of standard acoustics nomenclature, but it is useful for describing a category of sustained, non‑pitch-specific resonance.
