Music Block

Music Blocks are objects that appear in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2. They function identically to Note Blocks, the only difference being that, when an object falls on it, it will also play a short music note.

A Music Block can be placed by shaking a Note Block. The pitch of the note that is placed depends on the height: for example, a Music Block placed one block above the bottom of the level will play a low note, while placing it towards top of the level will play a high note. In addition to playing different pitches of notes, the instrumentation will also change depending on what falls onto it. Examples include Mario's sound being a steel drum, a Super Mushroom playing a chiptune, and a piano playing when a Goomba lands on one. Due to this functionality, users have created levels that play customized music using different objects falling onto them.
