A '''keyboard matrix circuit''' is a design used in most electronic [[musical keyboard]]s and [[computer keyboard]]s in which the key switches are connected by a grid of wires, similar to a [[diode matrix]]. For example, 16 wires arranged in 8 rows and 8 columns (8x8=256 total combinations) can connect 64 keys—sufficient for a full five octaves of range (61 notes). By scanning these crossings, a keyboard controller can determine which keys are currently pressed.<ref name="dribin"/>
