The Spaghetti Western
Many of the cowboy movies made in Italy during the 1960s and 1970s are well-regarded for their depictions of violence and complex characters (modern day think Quentin Tarantino). Arrangements were typified by horns, timpani and snare, whistling, telecaster guitar, choral accompaniment. Ennio Morricone's soundtrack to The Good, the Bad and the Ugly is probably the most iconic soundtrack in this genre.
Blaxploitation
These early 1970s films were aimed at black audiences. Featuring African-American actors in lead roles and often having anti-establishment plots, the movies were frequently condemned for stereotypical characterization and glorification of violence. Soundtracks are heavily influenced by the funk sound of that era.
Giallo
This genre is usually associated with a particular style of Italian-produced murder mystery blending the atmosphere and suspense of thriller fiction with elements of horror fiction (such as slasher violence) and eroticism.
Horror/Sci-Fi
Campy horror relies on melodramatic use of orchestra or electronics. The theremin is a classic horror/sci-fi instrument.
