Treble is one of the characters in One Man Band.
One Man Band
Treble is a suave and flamboyant street musician who came across another musician, named Bass, who played the same tune over and over again. Treble soon spots a little girl's coin, just seconds after Bass does.
Treble and Bass instantly become rivals, and fight over the Tippy's coin. But soon after that, Tippy accidentally drops the coin into a drain, and cries, and gets so angry at the two musicians. She request for them to give her a replacement coin, but they reveal they are poor and broke. She takes one of the Treble's violins, retunes it, and plays an unexpectedly impressive tune.
A rich man is pleased by her performance, so he gives her a big bag of coins, and the girl eagerly picks it up. Before leaving, she takes two coins for the one-man-bands and tosses them into the top of a fountain, where she was originally going to put her coin in for a wish. The two musicians are forced to work together in an attempt at reaching the top, where the two coins remain.
