There is a foldable musical keyboard player can convert from a deployed configuration to at least a first and a second folding configuration. In the deployed configuration, the top keyboard of the player is flipped up, exposing the music keys on both the top keyboard and the bottom keyboard. Such a configuration allows access to all the music keys and the control panel of the player, enabling the user to play music. By flipping down the top keyboard that covers the bottom keyboard, the player is converted into the first folding configuration, which transforms the player from a format adapted for playing to another more suitable for transport. By using a number of hinges and adjusting the fastening assemblies, the user may fold the keyboard player again, converting to the second folding configuration, which makes the musical keyboard player compact in occupied space and easy to transport and store.
