The Piano Player could very well be a large reel of paper, making the piano effectively a large music box.
When an actual person is used, they don't necessarily have more personality. This is a shame, as the ragtime music featured in most western saloons used heavy repetitions of notes that could very well be Level Grinding your arms into a level of badass.
Expect a competent professional musician in white shirtsleeves and slicked hair, often brought in from "out East" for the sole purpose of being able to play the latest songs as well as any request. (That doesn't stop them from playing almost the exact same tune in every bar.)
The Piano Player becomes an important device because although he is able to play for hours without a break, the mere mention of "Bad Bart" or any local Big Bad causes him to slam the keys once before the foreboding silence. Sometimes they comedically continue playing stoically while the bar behind them breaks out in a Bar Brawl, though they might also help out by playing more intense music while there's a fight. If one really wants to be nasty to the player, one could slam the wooden keyboard lid on their fingers.
However, their character is tied up in the piano and they rarely have any lines, with all questions about the bar being directed to The Bartender.
The Piano Player is a convenient justification for Source Music, which can lead to Suspiciously Apropos Music (for example a sudden shift to a more ominous tune when the bad guy enters) or a Left the Background Music On gag.
- Lucky Luke:
- There's always a piano player playing the instrument when a saloon brawl erupts. He'll inexplicably keep playing in such cases instead of seeking cover, dodging thrown bottles and bullets doing so (which will often create bullet holes in the instrument but won't alter its sound, as the various animated film and animated series adaptations show).
- A story has Luke become friends with one, who has ambitions of one day playing at Symphony Hall. He finally gets his chance but on the day of his performance he gets stage fright and freezes completely. Luke correctly guesses he's used to playing in bars with perpetual brawls going on so he barges in on Jolly Jumper and starts firing into the air causing the room to descend to utter chaos... and the player to get over his stage fright and start playing. They throw him out, of course, but he managed to live his dream.
- The comic book Munden's Bar features a piano player who has about twenty fingers on each of his hands.

- There is a Dick Tracy villain called 88 Keys, both in the comic strip and the Warren Beatty film.

- Snoopy will occasionally enter a bar and either make a request of the piano player, or begin playing piano himself in the cartoons.
- The recurring pianist is Schroeder, who plays only classical music. He does get lines (usually trading Lucy's flirtations for sarcasm), but in big crowd scenes he tends to stay in the background, hunched over his instrument.
- There's a piano player in The Great Mouse Detective, and although the film is not a western, he certainly fits the trope.
- Captain Hook fills this role in the bar scenes of the Shrek sequels, perhaps as a shout-out to the Affably Evil version in the Disney movie Peter Pan, or to the original book, where Hook is stated to be an accomplished harpsichord player, despite his disability. It's lampshaded in that, when sent with his men to capture Shrek and co. in the third film, they bring the piano along so he can provide music for the fight scene.

He's discovered by the villainous music producer Swan (played again by Paul Williams, who again wrote all the movie's songs) while playing piano in the background in Swan's club, mostly ignored by the patrons, after the headlining band's big music act is over.
- The Pianist features a rare instance of the trope being Played for Drama, and Based on a True Story to boot. Classical concert pianist Władysław Szpilman is forced to take cheap gigs in bars and restaurants when the Nazis take over Poland, since they didn't allow Jews to be in the arts. (Then it goes From Bad to Worse. Much, much worse).

- The main character in Shoot the Piano Player, François Truffaut's second film. The story is about a former classical pianist now working in a dive bar who ends up hunted by criminals thanks to his brother. Unusual in that the focus is on the piano player as the main character, rather than as comedic relief.
- In Singin' in the Rain Lina Lamont refers to Cosmo as this, even though he actually has a really big part!
Lina Lamont: You piano player, you!
- Doc Holliday takes a turn in this capacity in Tombstone.
- Technically, it's not a piano that Lurch plays in the The Addams Family (it's a harpsichord) but he still fills the role. (In fact, the iconic theme song is sung to harpsichord music, so he's likely the one playing it, especially since he's shown performing during the opening credits.)
- Piano players show up frequently on The Amazing Race as part of tasks, with the best example being Season 17's "Classical Music" Detour in Russia in which multiple pianists continue to stoically play their same pieces repeatedly over Racer hysteria at being unable to identify them correctly. The task itself had to be kept open for hours, though it's unlikely they had to play that long.
- In the Doctor Who serial "The Gunfighters", there's a subplot about the saloon trying to find a new piano player because their old one was shot last week. Eventually the Doctor's companions are forced to play at gunpoint.

At this point the girl who had hired Paladin realized her boyfriend was a lost cause and left.

- In the Korean Drama Shining Inheritance, an autistic child who is a genius on the piano is taken in by a bar owner, and eventually reunited with his family who is looking for him.
- Averted in Westworld where The Western bar has a pianola for Rule of Symbolism, played by a roll of punched paper.

- Freddy Pharkas: Frontier Pharmacist has a piano player called Neville Shute.
"You know, Neville Shute, the piano player... he's only doing his job."
- Plants Vs Zombies 2 has the Pianist Zombie, a Wild West-era piano-playing zombie. Naturally, the background music switches to saloon piano while the zombie is on the lawn. His music causes the basic zombies to dance and periodically switch lanes, while his piano can quickly crush any plant in its way.
- Any saloons featured in Red Dead Redemption tend to have one of these pounding away on the dance floor. Given the setting, it's to be expected.
- In Snoopy Flying Ace, Schroeder gets this role in a traditional sense, playing in a bar while the other characters discuss things with one another and bartender Linus (the game being a loving parody of/homage to old war movies).
- In West of Loathing, every saloon except the one in Breadwood has a piano player. The one in Dirtwater is out-of-tune when you first visit. Lloyd, The Bartender, explains that it's broken. Not the piano, the piano player: a Mysticality check reveals it's some sort of automaton.
Lloyd: Well, if you're handy with mechanical-type stuff, something's gone wrong with our player piano player.Player: I'll see what I can do.Lloyd: Thanks! I'd've poked around in him myself, but I lost the key.Player: This has suddenly taken a strange turn.

Billy the Kid: That's piano! I said piany!
- This similarly happens again in "Kill the Alligator and Run", where Homer is ordered at bullwhip to play the piano. He plays it badly at first, before being whipped once and then playing very well. (Homer has in fact been shown over the years to be quite the talented piano player, even writing his own sheet music, making it one of his many Weak, but Skilled abilities.)
