An object in the <i>[[Mario (series)|]]</i> series, appearing as a block with a [[quarter note]] on it.

Jumping on it causes [[Mario]] to bounce up, and also increases his jump height when he jumps off it.

<i>[[Super Mario Maker]]</i> introduces the Music Block, a variant with an [[eighth note]] on it instead of a quarter note. It plays a short musical note when hit or landed on.

<i>[[Super Mario Bros. Wonder]]</i> introduces the Marimba Block, a variant with [[beamed eighth notes]] on it. Unlike Note Blocks, they do not cause [[Mario]] and the others to bounce up, instead only increasing jump height.
