Tintinnabuli is a musical style developed by composer Arvo Pärt in the 1970s. It is characterized by a simple, bell-like sound, where two distinct musical lines interact. One line typically consists of a triad, while the other moves in a stepwise manner, creating a sense of harmony and clarity. This technique evokes a meditative quality, often drawing on spiritual themes. Tintinnabuli compositions are known for their minimalism and emotional depth, making them accessible and profound. The style has influenced many contemporary composers and is celebrated for its ability to convey a sense of peace and introspection.
