This is the symbol for a Coda, and usually it is accompanied by the word.
Coda is the Italian for tail, It means “the special bit at the end”.
You will find the symbol twice in the music – once where it says, “al Coda” or “To Coda”, and then at the end where the coda is written out.
There is no set length for a coda. Sometimes a coda, like a tail, is short and sweet.
Sometimes it is quite long and elaborate.
