arpeutuma

Arpeutuma is a term used in speculative music theory to describe a texture or technique that extends the idea of an arpeggio beyond a single chord into layered, cascading arpeggios that cross registers and voices. The concept has appeared in a small corpus of theoretical writing since the early 21st century, but it has not achieved mainstream adoption. The etymology is uncertain; the word appears to be a portmanteau combining arpeggio with a Latin-like suffix, though there is no consensus on its origin.

Practically, arpeutuma is associated with rapidly arpeggiated figures that are distributed across multiple instruments or synth voices, often involving irregular or microtonal timing to create evolving sonorities. It emphasizes continuity of pitch materials and the perception of arpeggiation as a continuous texture rather than discrete chords. Compositional approaches emphasize experimentation with register balance, rhythmic spacing, and timbral differentiation to maintain clarity while preserving arpeggial motion.

Usage remains experimental; a handful of contemporary composers and theorists discuss possible notational conventions, performance techniques, and cognitive effects. Recordings and scores citing arpeutuma are scarce and not standardized, making the term more of an analytical concept than a widely taught technique. As such, arpeutuma remains a fringe idea within ongoing discussions about texture and simultaneity in modern composition.
