Piano Keybuild is a small font designed for creating piano keyboard layouts. It was inspired by my Yamaha CLP-840, a wonderful digital piano. The face consists entirely of keyboard keys that can be combined to form realistic keyboards. These keys come in four styles: basic outlined keys, filler keys (for adding a second color inside the outlines), keys with note names, and pre-made sets of keys. Keys of a given kind will kern with one another, but only in the order that they would naturally occur on a keyboard. (This makes it easier to spot incorrect key sequences.) It also includes digits 0 through 9 inspired by numerals used in traditional music notation.
The included user guide demonstrates the locations of all the glyphs as well as how to use them together effectively.
