Abrams wrote, "Individually, each [giallo] is like an improv exercise in murder, with each filmmaker having access to a handful of shared props and themes. Black gloves, sexual ambiguity, and psychoanalytic trauma may be at the heart of each film, but the genre itself is without consistent narrative form." Content While a shadowy killer and mystery narrative are common to most gialli, the most consistent and notable shared trope in the giallo tradition is the focus on grisly death sequences. The murders are invariably violent and gory, featuring a variety of explicit and imaginative attacks. These scenes frequently evoke some degree of voyeurism, sometimes going so far as to present the murder from the first-person perspective of the killer, with the black-gloved hand holding a knife viewed from the killer's point of view. The murders often occur when the victim is most vulnerable (showering, taking a bath, or scantily clad); as such, giallo films often include liberal amounts of nudity and sex, almost all of it featuring beautiful young women. Actresses associated with the genre include Edwige Fenech, Barbara Bach, Daria Nicolodi, Mimsy Farmer, Barbara Bouchet, Suzy Kendall, Ida Galli and Anita Strindberg.

Themes Gialli are noted for psychological themes of madness, alienation, sexuality, and paranoia. The protagonist is usually a witness to a gruesome crime but frequently finds their testimony subject to skepticism from authority figures, leading to a questioning of their own perception and authority. This ambiguity of memory and perception can escalate to delusion, hallucination, or delirious paranoia. Since gialli protagonists are typically female, this can lead to what writer Gary Needham calls, "...the giallo's inherent pathologising of femininity and fascination with "sick" women." The killer is likely to be mentally-ill as well; giallo killers are almost always motivated by insanity caused by some past psychological trauma, often of a sexual nature (and sometimes depicted in flashbacks). The emphasis on madness and subjective perception has roots in the giallo novels (for example, Sergio Martino's Your Vice Is a Locked Room and Only I Have the Key was based on Edgar Allan Poe's short story "The Black Cat", which deals with a psychologically unstable narrator) but also finds expression in the tools of
