ABSTRACT:
Embodiments of an electronic, frameless, musical keyboard with the ability to couple to other frameless musical keyboards are described. In one embodiment, a first musical keyboard section includes an arrangement of black and white keys, similar to a layout of a piano keyboard, disposed over a base. The keys at the left and/or right sides of the keyboard section have exposed sides, so that a second keyboard section can be integrated with the first keyboard section to give the appearance of a single keyboard. To integrate the first keyboard section with the second keyboard section, the base of the first keyboard section extends past the right-most key to a width and length that is substantially equal to the dimensions of a left-most key from the second keyboard section. The left-most key can then be laid to rest over the extended base portion. The reserved space formed by the base of the first keyboard section having dimensions of a key (e.g., a standard white key of a piano keyboard) allows for consistent integration of another keyboard section (having any number of keys) with the first keyboard section.
