- Abbreviation
- a.s.p., ASP
How is a.s.p played?
In Grisey's string parts and other spectral scores, move the bow to an extreme bridge position where bright upper-partial noise can dominate and the fundamental may become barely audible—more extreme than an ordinary molto sul ponticello. The work's legend remains decisive, because Sirena, Mæland and Fineberg define different contact points and pitch-to-noise balances. The characteristic spectral result is therefore an important practice, not a universal acoustic prescription.
How does a.s.p sound?
Glassy, noise-edged colour where the upper partials swamp the fundamental.
In context
Grisey's documented scheme and publisher scores attest ASP, while direct scores by Sirena, Mæland and Fineberg use a.s.p. The forms are stable specialist shorthand for alto sul ponticello, but each score's legend governs the exact physical and acoustic result.
