Double Bass The double bass, also known as the contrabass, is the largest and lowest-pitched member of the violin family. With a distinctive, elongated body and sloping shoulders, the double bass is typically played standing up or seated on a tall stool. It features four strings, traditionally tuned to E, A, D, and G, with the pitches an octave lower than the cello. The double bass is played with a bow or by plucking the strings with the fingers, known as pizzicato. Its deep, resonant tones provide a foundational and rhythmic support in various musical genres, including classical, jazz, and popular music. The instrument plays a crucial role in orchestras and jazz ensembles, contributing to both melodic and rhythmic elements.
