Final answer:
The mnemonic "Every good boy does fine" used for remembering the notes on the treble clef in piano is an acrostic, which is a sentence where each word's first letter aids memory retention of a sequence.
Step-by-step explanation:
When learning to play the piano and remembering the notes E, G, B, D, and F on the lines of the treble clef, the phrase "Every good boy does fine" is an example of an acrostic. This mnemonic device uses the first letters of each word in the phrase to represent the music notes on the staff, making it easier to recall them. While acronyms form a word from the first letters of each word in a sequence, acrostics use sentences where each word's beginning letter stands for an item to be remembered.
An example of acoustic encoding can be when a song you haven't heard in years plays on the radio, and you still remember the lyrics. This happens because our brains encode the sounds that words make. In music, this acoustic property is very prominent, as seen in individuals with perfect pitch, who can identify musical notes just by hearing them. However, the mnemonic for piano notes is not based on the concept of acoustic encoding but on a memory aid to help remember a sequence of letters.
