Claviation is a rapid and intuitive method for transposing an electronic musical keyboard in real timefast enough to support key changes during play using the keys themselves. The player enters transposition mode via a pedal or button and presses two keys in sequence to define the transposition interval. These two presses are muted to avoid disrupting the music. This three-step action is as efficient as a musical triplet, easily fitting within a beat and becoming faster with practice. Crucially, claviation requires no calculation, naming, or conceptualizing of intervals. It enables the player to keep scales primarily on the white keys, even through key changes, eliminating the need to learn key signatures and multiple fingerings. A piece learned in one key is effectively learned in all. Claviation accelerates learning, enhances improvisation, and preserves spatial patterns across key changes, making the keyboard easier to learn, understand, and compose music on.
