In Classical music, the composer typically orchestrates her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a pop songwriter may not use notation at all, and instead compose the song in her mind and then play or record it from memory.
Some Minecraft blocks. Blocks are a type of item in Minecraft. They make up the in-game environments, and they can be collected and utilized in different ways. Some blocks spawn naturally, such as Dirt or Stone, while others, such as Bricks or Redstone Lamps, must be crafted by the player.
The process of putting data into blocks is called blocking, while deblocking is the process of extracting data from blocks. Blocked data is normally stored in a data buffer and read or written a whole block at a time. Blocking reduces the overhead and speeds up the handling of the data-stream. For some devices such as magnetic tape and CKD disk devices blocking reduces the amount of external storage required for the data. Blocking is almost universally employed when storing data to 9-track magnetic tape, to NAND flash memory, and to rotating media such as floppy disks, hard disks, and optical discs.
