| | Musical keyboard - Wikipedia, the free encyclopedia |
 | | A musical keyboard is the set of adjacent depressible levers on a musical instrument which cause the instrument to produce sounds. |
 | | Musical instruments with keyboards of this type include the piano, harpsichord, clavichord, organ, synthesizer (or electric keyboard), celesta, accordion, melodica, glasschord, and carillon. |
 | | The twelve notes of the Western musical scale are laid out with the lowest note on the left; the larger keys (for the seven "natural" notes of the C major scale: C, D, E, F, G, A, B) jut forward. |
