Sudoku

You must solve the sudoku puzzle below to find the passcode to access more prizes. Sudoku is a number game where there are nine boxes with nine boxes within them. To solve it, arrange the numbers 1-9 in the boxes so that no number appears more than once in each large box or row up or down. Once you've solved the puzzle, enter the numbers that appear in the boxes with the faded pixel music notes in them into the password field below. They go in order left to right, top to bottom (illustrated by the image below). The username you need to input is sudoku.
