Kontakte (German: [kɔnˈtaktə] ⓘ, 'contacts') is an electronic music work by Karlheinz Stockhausen, realized in 1958–60 at the Westdeutscher Rundfunk (WDR) electronic-music studio in Cologne with the assistance of Gottfried Michael Koenig.

[7] The score is divided into sixteen sections with many subsections, numbered I A–F, II, III, IV A–F, V A–F, VI, VII A–F,VIII A–F, IX A–F, X, XI A–F, XII A1BA2, XIII A, Ab, Ad, Ae, Af B–F, XIV, XV A–F, and XVI A–E [and F].

According to the composer, "In the preparatory work for my composition Kontakte, I found, for the first time, ways to bring all properties [i.e., timbre, pitch, intensity, and duration] under a single control",[8] thereby realizing a longstanding goal of total serialism.

On the other hand, "Kontakte is arguably the last of Stockhausen's tape pieces in which serial proportions intervene decisively at anything but the broad formal level".

As it crosses this threshold, it becomes evident that the sound consists of a succession of pulses, which continue to slow until they become a steady beat.
