According to a forthcoming report from Claudette Hodges of the Sigmund Freud Foundation, the only musical instrument that facilitates all of the stages of Freud’s Psychosexual Development is the Holton TR395 Superbone, which functions as both a valve- and a slide-trombone.

Here are some highlights from the forthcoming report:
The Oral Stage:
Some trombonists enjoy secretly emptying their spit-valves directly into their own mouths.
The Anal Stage:
This one seems like a stretch to us (ahem), but according to Claudette, some trombonists deliberately allow rust to form on their mouthpieces and enjoy the sensation of the rust on their lips. She connects this to the fascination with one’s own waste and with the exploratory notion of ingesting one’s own fecal matter
The Phallic Stage:
This involves the trombonist fully exploring his or her slide, stretching to achieve the longest distance possible, and experimenting with fast and slow hand movements to achieve maximum satisfaction.
The Genital Stage is what makes the Superbone the ideal instrument for psychosexual development. Superbonists derive special pleasure from the dualism of their instruments’ mechanical parts, and this flexibility results in a healthy openness to a wide variety of sexual experiences. Freud would have argued that this leads to healthy heterosexual behavior, but Claudette prefers the 21st-century notions of pansexuality and hermaphroditism. Operating both the valves and a slide, the instrumentalist uses a variety of fingering techniques and “positions” to achieve his or her full potential.
