i had decided to remix your remix that made a more energetic version
by replacing the beginning with this
var transpose = 3;
var bpm = 314; // Beats per minute
var spb = 50/bpm; // Second per beat

function note(n, octave){
n += transpose;
return Math.pow(2, (n - 33 + (12 * (octave || 0))) / 12) * 1000;
}
(made an account just to comment this because im proud of myeself as i cannot code at all)
