We will be comparing the Graphics of Twinkle, Twinkle, Little Star (shown in red for Levels 0, +1, and +2)
and the Graphics of The Brahma Little Waltz, which is twice as long.
The positions of the horozontal bars are, for all intents and purposes, identical,
with the sole exception of the last fall (Beat) of Level +2 at the very end of Twinkle, Twinkle, Little Star
which exists in the middle of The Little Waltz but not at the very end (the "-1" in the "2n - 1" formula).
The vertical bars (upright or slanted), which determine the grouping of the horizontal bars,
are not at all the same and the groupings are completely different.
In Twinkle, Twinkle, Little Star the bars are vertical and the grouping is binary, whereas
in The Little Waltz the bars are slanted and the grouping is ternary.
The interlocking of the levels is also completely different in the two cases.
