Note Block

A Note Block (originally Jump Block and also known as Music Block ) is a type of bouncy block introduced in Super Mario Bros. 3, usually appearing as a white cube with an animated quarter note (♩) on each lateral side. Mario bounces up and down infinitely while on top of one, and can achieve greater vertical movement if the jump button is pressed as he's being launched upward.

Super Mario Bros. 3
In Super Mario Bros. 3, Jump Blocks first appear in World 1-2. They occasionally hold a power-up for the player if they bounce on it or hit it like a ? Block.

Also in Super Mario Bros. 3, there is a special variety of salmon-colored Jump Blocks called Magic Note Blocks hidden in some courses that catapult Mario or Luigi to Coin Heaven, where many coins and a 1-Up Mushroom can be found. Two of the e-Reader card levels in the GBA remake consist entirely of Jump Blocks: Magical Note Blocks and A Musical Trek.

Super Mario World
Jump Blocks reappear in Super Mario World, and behave the same as in the predecessor.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Jump Blocks are redesigned with a white-green checkered pattern, although they act the same. These checkered blocks are uncommon and can be found in stages such as World 7-5, Lakitu Enemy Courses, and in Iggy's castle. As of this game, Jump Blocks do not hold power-ups.

Super Mario 3D Land
Note Blocks later appear in Super Mario 3D Land (making their first appearance in a 3D Mario platformer game), where they serve the same purpose. However, they retain their original designs, and most of them are two blocks wide (though in the box art and in certain courses, they retain their earlier proportions). They also make musical sounds and notes appear when they are jumped on; in a pre-release trailer, they can be heard making the orchestral hit noise used for Yoshi's voice in older games, but this was removed from the final game. Magic Note Blocks return and are renamed Super Note Blocks; they once again send Mario to a Coin Heaven area, but now are twice as long, flash colors, and have a white note on their sides.

New Super Mario Bros. 2
Note Blocks also appear in New Super Mario Bros. 2. Here, they all retain their appearance from most other 2D platformers. However, the musical notes and sounds (now based on the chords of the game's music) return from Super Mario 3D Land.

Similar blocks known as Trampoline Blocks make an appearance. Unlike Note Blocks, they do not have the music aesthetic, are blue with a black diamond shape imprinted, and the player cannot control how high Mario bounces off the block.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Note Blocks later appear in New Super Mario Bros. U and New Super Luigi U, as well as their shared port. They behave mainly the same as in previous installments, except they now play a fixed note when bounced on.

Super Mario Maker / Super Mario Maker for Nintendo 3DS / Super Mario Maker 2
Note Blocks return in Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2, where they can be used in all of the styles, excluding Super Mario 3D World. While it retains its appearances in Super Mario Bros. 3, Super Mario World and New Super Mario Bros. U, it features a new sprite for its Super Mario Bros. appearance. Pink versions called Music Blocks also appear, using an ♪ eighth note instead of a ♩ quarter note.

The Adventures of Super Mario Bros. 3
These blocks also appear in the TV series The Adventures of Super Mario Bros. 3, where some have ♫ two beamed notes instead of a ♩ quarter note.

Super Smash Bros. series
In Super Smash Bros. for Nintendo 3DS and Super Smash Bros. Ultimate, a Note Block appears on the 3D Land stage, having the same function as in the Super Mario games.

Mario & Luigi: Paper Jam
In Mario & Luigi: Paper Jam, when Mario, Luigi, and Paper Mario are rescuing Paper Toads in Sunbeam Plains in the mission Paper Toad Rescue, a row of five Note Blocks can be found. A purple Paper Toad can be found jumping on the blocks, and he can be rescued by hitting one of the blocks while he is on it. Another Note Block can be found in the mission Fly Guy Flyby, where it can be found behind a crack that only Paper Mario can fit in. A Fly Guy holding a Paper Toad can be found above it, and hitting the Note Block causes the Fly Guy to fly away. In the mission Paper Toad Shuffle, two more groups of Note Blocks can be found, each with a purple Paper Toad jumping on them.
