Note Block
From SMWiki
Note Blocks are square-ish blocks in the game Super Mario World. They are the least common blocks out of Turn Blocks and ? Blocks. They were originally introduced in Super Mario Bros 3., serving the same purpose.
Description
When you jump on a note block, a sound effect plays and Mario bounces off of it. Time your jump correctly on a note block and you can jump super high! Other varieties will yield items such as a Feather, Fire Flower, or a Star. This block cannot be destroyed, nor will it turn into Brown Used Block. There are also a few types of note blocks that were programmed into Super Mario World, but never used in any of the levels. One unused note block will act like the regular one, except you can bounce off from all sides! Another note block variety is invisible, and it will only appear when Mario hits it from below, like it's ? Block counterpart. Note Blocks also require the use of a specific sprite graphic so they look normal when bounced on or hit from below.
