Eberhard Weber (born 22 January 1940, in Stuttgart, Germany) is a German double bassist and composer. As a bass player, he is known for his highly distinctive tone and phrasing. Weber’s compositions blend chamber jazz, European classical music, minimalism and ambient music, and are regarded as characteristic examples of the ECM Records sound.

Weber began recording in the early 1960s, and released The Colours of Chloë (ECM 1042), his first record under his own name, in 1973. In addition to his career as a musician, he also worked for many years as a television and theater director. He has designed an electric-acoustic bass with an additional string tuned to C.

Weber’s music, often in a melancholic tone, frequently utilizes ostinatos, yet is highly organized in its colouring and attention to detail. He was an early proponent of the solid-body electric double bass, which he has played regularly since the early 1970s.

From the early 1960s to the early 1970s, Weber’s closest musical association was with pianist Wolfgang Dauner. Their many mutual projects were diverse, from mainstream jazz to jazz-rock fusion to avant-garde sound experiments. During this period, Weber also played and recorded with pianists Hampton Hawes and Mal Waldron, guitarists Baden Powell de Aquino and Joe Pass, The Mike Gibbs Orchestra, violinist Stephane Grappelli, and many others.
