Definition: The word 'abstrude' is a term derived from Greek, meaning to cut down or reduce to a simpler form. In music, this is often done by reducing an existing melody or chord progression into smaller parts called "lines." These lines are then arranged together in a sequence known as an "arpeggio," which can be used to create a more complex sound. For example, if you had a simple melody of two notes, you might use the word 'abstrude' to cut down on it and reduce it into three parts. This would result in a more abstracted version of the original melody, with each note now having its own separate "line" or "arpeggio." The aim is often to create a sense of separation between the musical notes, which can be achieved by reducing them to simpler forms. The word 'abstrude' is particularly useful when working with improvisation in music, as it allows musicians to create new sounds and textures without having to invent entirely new melodies or chords. It's also used in the context of classical music where it refers specifically to removing a complex piece from its original structure to create a more accessible and easier-to-perform version.
