Grand Piano Keys is an arcade game by Bay Tek Entertainment. The only point of the game is to perform as much of a public domain song as possible in 20 seconds. This is done by hitting the huge, simple piano keys that match the on-screen tiles. If a player hits the wrong notes, they can't play for a few seconds and they lose some of their time. In the end, the game suddenly stops, and tickets are rewarded based off of how many keys you hit.
Grand Piano Keys provides examples of:
- Artistic License – Music: The game uses a piano with much fewer notes than a real piano, and the keys don't always match the music. This is done to make the game simpler to play.
- Attract Mode: When no one's playing the game, it will go into an attract mode showing tiles scrolling across the screen.
- Color-Coded Multiplayer: Player 1 has blue notes and player 2 has green notes.
- Color Contrast: The logo stands out by having black text over white piano keys.
- Colour-Coded for Your Convenience: The correct notes are either blue or green, depending on the player, and the incorrect notes are white.
- Competitive Multiplayer: In the two-player mode, two players compete against each other to hit the most keys within 20 seconds.
- Debug Room: The game includes a debug menu with options to change the volume, Attract Mode, songs, etc.
- Dreadful Musician: This trope is penalized. Every time you hit a wrong note, you can't play for a few seconds, and you lose some of your time.
- Instrumental Theme Tune: The game uses short piano music on its title screen with no vocals.
- Let's Duet: The game offers the choice of "dueling piano keys" which is when two people play the piano at once.
- Minimalism: This game contains the bare minimum of graphics and sound to work as a piano game. It has simple rectangles for its graphics and simple piano sounds for the music.
- Musical Gameplay: The game only makes sound when you hit the correct piano keys.
- Musicalus Interruptus: After you play the piano for 20 seconds, you get interrupted by the end of the game.
- No Ending: No matter how well you do, the round stops after 20 seconds without a satisfying ending.
- No Plot? No Problem!: There's no plot or even characters. The only point of the game is to hit the piano keys.
- Palette Swap: The same tiles are used for both players, only colored differently.
- Player Versus Player: In the two-player mode, two players compete against each other to hit the most keys within 20 seconds.
- Public Domain Soundtrack: All of the songs in the game are well-known public domain melodies.
- Score Screen: The game includes a score screen showing the people who hit the most keys in 20 seconds.
- Scoring Points: The more piano notes you hit, the more points you get. The points are counted as piano keys and converted to tickets.
- Socialization Bonus: If you play with a friend, you'll have twice as much of an opportunity to earn tickets that you can use after the game.
- Sound Test: The debug menu includes a menu of songbook settings that contains all of the songs in the game.
- Standard Snippet: The game uses recognizable public domain piano songs as its soundtrack.
- Tagline: "Worthy of a Standing Ovation!"
- Timed Mission: You have 20 seconds to perform as much of the song as you can and earn the most tickets.
- Title Theme Drop: The music played on the title screen is reused once the game starts and the person performs the song.
- Unstable Equilibrium: If you're good, you won't miss too many keys and you'll be able to score a lot of points within the time limit. If you're bad, you'll keep missing keys and losing time, and you won't have enough time left to improve.
